Description

Radiation effects in semiconductor devices have come to play a major role in the performance and reliability of today’s electronics. Several questions also arise from emerging applications (such as self-driving cars, nanosatellites, medical implants etc.). As the demand for radiation hardness testing is on the rise, the availability of radiation facilities providing industrial access to perform these tests at least for certain radiation types are not able to catch up with the increasing demand. Traditional testing methodologies also seem to be limited in face of new semiconductor technologies, the increased usage of commercial components of the shelf and new applications fields.

The RADNEXT program – an H2020 INFRAIA-02-2020 infrastructure project – started in June 2021 and is addressing most of these challenges. In particular, it aims at bridging the gap between industrial and academic users of radiation hardness testing and the irradiation facilities providing beam time to them. This workshop is primarily dedicated to the whole industrial community where radiation effects in semiconductor and other microelectronic devices play a crucial role: i.e. the chip designers, the foundries, space companies the end users, the testing companies and the testing equipment manufacturers and many more. The aim of the workshop is to connect the stakeholders from industry with radiation effects experts from academia and representatives from irradiation facilities to stimulate discussion, in the framework of the RADNEXT Initiative.

Building upon the experience, notably linked to the very positive outcome and feedback of the G-RAD workshop in December 2020, the G-RAD(NEXT) workshop in May 2022 and the in-person G-RADNEXT workshop at CERN last November with more than 80 person on site, we propose you to join us in June 2024 and continue from where we left last year. We are proud to announce that the workshop venue will be at the Rutherford Appleton Laboratory in Harwell, UK.

09:35 Talk 1: After ChipIr - Irradiation Prospects on ISIS-II

Abstract:

In order to meet the increasing needs of the electronics industry for neutron single-event-effect testing the ISIS Neutron and Muon Source designed and built a new test facility, ChipIr, on its Second Target Station. The ChipIr design presented a number of challenges and opportunities as it was the first time a fast-neutron beamline had been incorporated into an existing target station that was primarily designed for neutron scattering in condensed matter at thermal energies.
The plans for ISIS-II, a next-generation neutron and muon source, provides an opportunity to develop the next generation of fast-neutron irradiation facility, building on the lessons learned from ChipIr and other irradiation beamlines. ISIS-II will also provide opportunities to develop capability in proton and muon irradiation alongside the neutron provision.
In this talk I will present some of the ideas and scenarios that are being developed for irradiation provision within the ISIS-II project.

CV:

Christopher Frost joined the ISIS Neutron and Muon Source, Rutherford Appleton Laboratory in 1998. As a research scientist interested in state-of-the-art instrumentation he was initially involved in the building of MAPS, the first single-crystal direct-geometry spectrometer on a pulsed neutron source and the introduction of polarized He3 technology to ISIS. More recently he led the efforts at ISIS to develop new beamline for neutron single-event-effect testing and subsequently established the irradiation team at the facility which he now leads. As Head of Irradiation, he continues to be responsible for operating and developing further capability for the neutron testing of electronics for a global list of commercial and academic users.

09:55 Talk 2: ECHIR: a Beamline for Chip Irradiation at ESS

Abstract:

In the design and construction phase of the European Spallation Source, a considerable effort was devoted to investigating the possibility of a chip irradiation facility [1]. A neutronic study of a beamline for fast neutrons originating in the spallation reaction induced by the high energy proton beam on the ESS tungsten target was conducted, resulting in the selection of a beamline placed in the forward direction with respect to the incoming proton beam, and directed downwards into the basement of the target building. The characteristics of the neutron beam, in particular the beam profile, the beam footprint, and the energy spectrum, in a location at about 10 m distance from the spallation target were determined. Additionally, a beam dump was designed. Following this study, some essential components of this ECHIR beamline were designed, built, and installed at ESS, including a channel for fast neutron extraction, a beam shutter, and a beam dump. These components constitute a provision for a future possible chip irradiation facility at ESS. In this talk, I will summarize the neutronic design, show the components that have been installed at ESS, and discuss future possibilities for this facility.

CV:

I have a PhD in neutron physics and worked for 30 years with neutrons. I have worked at ESS since 2011, where I have designed some components such as the neutron moderators for cold and thermal neutrons production for neutron scattering experiments, and the neutron bunker for biological shielding. I am currently helping on finishing the construction of the facility and designing future upgrades.

Abstract:

The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL), presently the highest power spallation neutron source worldwide, is in the final stages of its power upgrade from 1.4 to 2.8 MW. I will discuss the facility performance with particular focus on the opportunities offered by the high power to support applications in addition to the primary neutron scattering mission. A few kW of extracted beam can support applications such as irradiation and isotope production, and a portfolio of fundamental physics experiments.

10:19 Talk 4: IFMIF-DONES neutron irradiation facility

Abstract:

IFMIF-DONES (International Fusion Materials Irradiation Facility – DEMO Oriented Neutron Source) [1,2] is a pioneering accelerator-based neutron irradiation facility currently under construction in Granada, Spain. It is a part of the European roadmap to fusion electricity and a key laboratory to prepare for the construction of the DEMO fusion power plant.
The main mission of DONES will be to perform high dose rate irradiation of structural and functional materials using an intense neutron flux with an energy spectrum similar to that expected within fusion reactors. IFMIF-DONES will also become a multidisciplinary neutron science facility covering a wide range of applications, including, among others, tritium breeding experiments for the fusion fuel cycle, nuclear physics studies, neutron imaging, biological, medical and industrial application of neutrons.
The facilities for complementary experiments at DONES will feature a collimated neutron beam experimental area in which several irradiation stations can be arranged in a sequential configuration. The neutron flux of the order of 1013 m−2 s−1 in a continuous beam mode can be used for experiments either directly or after passing through a moderator. It is also planned to implement a neutron Time-of-flight experimental area for measurements with pulsed beams of neutrons of selected energy.
In this contribution I will show the main design features, construction status and plans for neutron irradiation facilties at IFMIF-DONES. The opportunities for industrial irradiations of materials and components in a mixed neutron and gamma radiation field at DONES will be presented for discussion.

10:31 Talk 5: Progress of atmospheric neutron irradiation research at ANIS

Abstract:

In recent years, an atmospheric neutron beamline was strongly advocated in China by the domestic industries related to semiconductors, aviation, power electronics, etc. In 2017, the Atmospheric Neutron Irradiation Spectrometer (ANIS) was approved by Department of Science and Technology of Guangdong Province, for China Electronic Product Reliability and Environmental Testing Research Institute, Guangzhou and for Spallation Neutron Source Science Center, Dongguan. The conceptual design, physical design and mechanical construction of ANIS were then started at the China Spallation Neutron Source (CSNS) [1,2]. The initial commissioning tests of this new neutron irradiation facility were completed in 2022. ANIS is now in the scientific commissioning status.
ANIS views the front part of the spallation target directly, extracting neutrons produced via the spallation reactions from meV to GeV. The most prominent feature of ANIS is the differential neutron spectrum that resembles the atmospheric neutrons, with a wide adjustability of neutron flux and beam spots. The initial evaluation of the broad neutron spectrum was once performed with the simulation results [3]. We have measured the beam parameters including neutron spectrum, beam spots and neutron flux [4]. We have conducted some experiments to verify the impact caused by thermal neutrons, accompanying protons and multilayer circuit boards on the neutron irradiation effects at ANIS. In addition, a series of neutron irradiation tests for electronic components and equipment were performed for the users [5,6]. In this work, we present the progress of neutron irradiation research performed at ANIS, including its current status and future perspectives.

10:43 Talk 6: Capabilities of the n_TOF spallation facility at CERN for electronics testing

Abstract:

The capabilities of neutron time of flight (n_TOF) spallation facility at CERN was investigated for electronics testing, as the demand of testing in such facilities is increasing and their availability in the worlds is limited. The neutron fields in a recently consolidated irradiation station (NEAR) are studied through Monte Carlo simulations, well-characterized static-random-access-memories (SRAMs) and radio-photo-luminescence (RPL) dosimeters. The neutron spectra at NEAR can reach up to 830 MeV and are compared to those of the most well-known spallation sources and typical environments of interest, for accelerator and atmospheric applications, showing the potential of the facility for electronics irradiation. In addition, an experimental area, typically employed for nuclear cross section measurements, is also investigated, which provides a neutron spectrum up to 12 GeV.

14:05 Talk 1: Current capabilities and future requirements in radiation testing in Europe

Abstract:

It is long established that terrestrial cosmic radiation (TCR) can lead to the destruction of semiconductor power devices - such as diodes, MOSFETs or IGBTs – for a large range of voltage classes (~ 300 – 7000 V) [1]. The general mechanism are neutron-nucleus collisions that create highly energetic spallation fragments within the device, and which can deposit sufficient energy to lead to irreversible device failure. Depending on application parameters, TCR-induced failures can become a significant factor regarding device reliability and must be determined consistently before field application by the manufacturer.
Reliability requirements for single chips are usually in the range of 0.01 - 100 FIT (Failures in time), with 1 FIT being 1 fail in 109 device hours. To quantify such low failure rates accelerated tests are necessary, in which case artificial neutron sources are used which have fluxes that are several orders of magnitude above the natural TCR [2]. Currently, the only instrument in Europe with atmospheric-like neutrons that fulfills the requirements for industry standardized testing is the ChipIR instrument at the ISIS spallation source, UK.
However, the ever-growing market for power semiconductor devices - driven e.g., by the rising adoption of renewable energy sources, IoT devices and automotive electronics – will significantly increase the demand for testing capacities in upcoming years. Considering that the market is highly competitive with fierce competition from American and Asian companies, who coincidentally also have more testing sources available, emphasizes the need for a second source for atmospheric-like neutrons in Europe.
In this contribution current capabilities and future requirements in radiation testing are presented from the perspectives of semiconductor manufacturers. In particular, our need for new artificial sources in Europe and their envisioned characteristics will be discussed.

14:25 Talk 2: Temperature dependence of Cosmic Ray failure mechanism in the SiC Power MOSFET (UK - SWIMMR Program)

Abstract:

This study was performed inside the UK-Space Weather Innovation Measurement Modelling Risk (SWIMMR) dedicated to space weather and its effect on terrestrial electronic devices. It was performed in cooperation with ISIS-CHPIR and the Physics and Chemistry Department of Palermo University and STMicroelectronics.
The cosmic ray impacts in the atmosphere make new particles clusters and under 20km of altitude the main particles present are neutrons, and they can produce effect in electronic devices. For Power devices, they induce a Burn-out and the devices are over.
Today the extensive use of new Power Devices with Wide Band Gap material in automotive applications requires accelerated neutron testing to identify the failure mechanism. This study is addressing the temperature effects in the neutron interaction of SiC Power Mosfet, which is mandatory to estimate the failure in time for the mission profile.
The new WBG material is being deployed in new application solutions in avionics. New services are under development, for example City Air Mobility which will use the new electric vehicle drone for the civil mobility. This increase of power devices in more and more electrical vehicles will require an intensive neutron test characterization. Moreover, the new space era with the presence of private industries in space missions and new low orbit constellation satellite will require more and more heavy ions characterization of standard automotive component for space use.
This scenario leads to the need to increase the number of both the neutron and heavy-ions facilities present in Europe. For the neutron facility, we plan an investigation of the effects on electronic component of the higher neutron energy (> 800MeV), because this energy could be present in avionics altitude.
In the presentation, we will be share the testing methodologies used, the results obtained and a requirement for new facilities based on the above scenario.

14:45 Talk 3: Product Resilience Design Validation Beam Test

Abstract:

For high performance network products and system, the resilience by design to tolerant SEE is vital in terrestrial level application due to large volume of installation in the field. Cisco’s resilience design is based on the rate vs. recovery time that is proportional to the customer impact. We take the beam test as the design validation approach. The network product (hardware + software) will be put under the high energy radiation particle and we observe the failures, impact and recovery through hardware or software. Here we will provide a high level view how we conduct the beam test, observe the SEE impact and drive the continuous improvement.

15:05 Talk 4: Radiation Experiments on AI accelerators: Current and Future Challenges and Opportunities

Abstract:

Complex AI accelerators, such as Graphics Processing Units (GPUs) or dedicated accelerators implemented in Field Programmable Gate Arrays (FPGAs) or in Application Specific Integrated Circuits (ASICs), such as the Google’s Tensor Processing Unit (TPU) are rapidly making their way in the chip market. Embedding AI is extremely interesting for automotive, productions lines, and aerospace. To be implemented, a self-driving system needs to analyze a huge amount of images and signals in real time. Nonetheless, guaranteeing sufficient reliability is challenging since both the hardware architecture and the running software are highly complex. It is then hard to characterize the radiation reliability of the framework and the experimental data risks to be biased to the specific configuration chosen for the experiment.
In the talk we will investigate the challenges related to the reliability evaluation of GPUs, FPGAs, and TPUs executing neural networks. The evaluation, to be accurate and precise, is based on the combination of beam experiments and fault injection at different levels of abstractions (RTL, microarchitectural, and software). This combination allows us to have a realistic evaluation of the error rate, distinguish between tolerable errors and critical errors, and to design efficient and effective hardening solutions for neural networks.

15:25 Talk 5: Soft Error Rate Test Methodology For Advance Process Nodes Under Neutron Beam At ChipIR

Abstract:

Soft Error Rate (SER) testing is crucial for evaluating the robustness of advanced process nodes offered by various foundries, particularly those caused by high-energy neutron particles. We derive the Failure In Time (FIT) numbers using a test setup specifically designed to comply with the JEDEC Spec JESD89-3B. This setup is tailored to assess the SER sensitivity of SRAM bit cells (both 6T and 8T, along with various peripheral physical designs) and Flip-Flops using different pattern backgrounds. ChipIR provides an ideal environment for our testing, offering flexible chip placement options and a consistent beam with uniform flux and fluence.
Over the past seven years, we have conducted experiments on eight different test vehicles across three different trips. The results have been consistently reliable, with extremely small error bars. These test vehicles have dedicated hardware built-in to collect SER data, enabling us to determine highly accurate FIT numbers. Additionally, our hardware allows us to pinpoint the physical location of each bit cell failure and differentiate between Single Event Upset (SEU) and Multi Event Upset (MBU) FIT rates.

16:50 Talk 2: Short and long-term user needs and possible upgrades for current and future irradiation facilities

Abstract:

The RADNEXT project aims at bridging the gap between the offer ensured by a series of irradiation facilities and the existing industrial and scientific requirements from the radiation effects community and beyond. With the ambition to make the most efficient use of diverse beam sources and tackle the emerging needs of irradiation experiments, this scientific collaboration provides relevant opportunities to leverage a broad network together with research facilities and international users.
One of the tasks of RADNEXT is to assess the performance of the partner infrastructures and identify limitations in the current offer. This study has been addressed by the work package WP4 in RADNEXT, producing an updated summary of the presently available irradiation facilities worldwide (https://irradiation-facilities.web.cern.ch/publicDB.php), and summarizing the status of the most frequently used irradiation facilities as function of the limiting factors found.
After carrying out two surveys that involved a wide spectrum of users and some RADNEXT facility coordinators, the outcomes enabled to determine short-term and long-term facility needs for relevant applications (sensors and detectors irradiations, materials, electronics component, and system tests) as well as their operational bottlenecks.
The purpose of this talk is to discuss this analysis and outline the different challenges faced by both the research infrastructure and user sides. This will serve as input to propose recommendations and solutions to tackle some tangible issues as well as develop common strategies to ensure the future suitability of irradiation facilities for a large panel of use-cases.

17:15 Talk 3: Remote radiation hardness campaings at facilities: Challenges and Perspectives

Abstract:

As the demand for Commercial off the Shelf (COTS) components in electronics destined for radiation environments grows, so does the importance of radiation testing. Yet, this necessity is met with obstacles inherent to radiation testing procedures, such as cost, facility access, test preparation and logistical coordination between external users and facility staff. Given these challenges, remote testing emerges as a promising solution, offering the potential to significantly alleviate the burdens associated with conducting a
radiation test campaign. External users would benefit from the convenience of conducting experiments without the need for physical presence at the facility, thereby minimizing logistic costs and enabling remote access to experiment data. However, while remote testing presents a promising solution, its successful implementation necessitates great effort from both external user and facility staff.

09:35 Talk 2: How synchrotron light sources can help overcome the major limitations related to Heavy Ions Single Event Effects testing in electronic circuits

Abstract:

Traditionally, heavy ion (HI) tests for Single Event Effects (SEE) qualification are conducted at cyclotron facilities with energies around 10 MeV/n. However, this testing method presents several drawbacks. Firstly, a demanding sample preparation is needed to probe the sensitive part of the component, which may not be possible for novel flip chip bonding technologies or 3D packaging and stacked dies. Secondly, obtaining beamtime at the facilities is difficult due to overbooking, and thirdly, HI source beam sizes are large, making it challenging to identify the exact location of the sensitive part.
In recent years, methodologies that use photons (lasers) to generate electron-hole pairs in materials have been used and validated to emulate the effects of HIs. However, this does not solve the problem of sample preparation. Pulsed synchrotron has been shown to be an effective tool to emulate HIs and test electronic circuit sensitivity to ionising radiation. X-ray beams with high-energy photons (1 keV < E < 30 keV) can penetrate most metallization layers and have a large penetration depth in the semiconductor, enabling access to every embedded component within a 3D-chip. Furthermore, the X-ray beam can be focused below one micron.
This talk will discuss the challenges, opportunities, and trends of using pulsed synchrotron to emulate HIs and test electronic circuit sensitivity. The state of the art of this methodology, as well as the characteristics of different sources available, will be presented in the context of the synchrotron light sources landscape. Pioneering experiments carried at the APS in Chicago (USA) [1] and at the ESRF of Grenoble (France) [2] will also be reviewed.

09:55 Talk 3: How pulsed laser SEE testing aids the space qualification of EEE components

Abstract:

As access to heavy ion beam time for radiation testing has become increasingly difficult during recent years, interest in using pulsed lasers to quantify single-event effect rates has steadily grown. Whilst there are limits to the types of device that can be tested with a laser, the technique offer numerous benefits for screening and de-risking, while offering the potential for much faster access to data. These benefits are now enabling the role of laser testing to be defined.
This presentation will outline the principal benefits of using a pulsed laser test system to simulate heavy ion testing and put forward the author’s thoughts on how laser testing can fit into the landscape of single-event effects radiation testing. Examples of results obtained via laser testing will be included.

10:15 Talk 4: Muon-induced Soft Errors in FinFET and Planar SRAMs

Abstract:

Transient malfunctions (soft errors) caused by secondary cosmic ray particles raining down on the Earth have become a major factor determining the reliability of information systems. Until now, the technology to evaluate soft errors mainly focused on neutrons contained in secondary cosmic rays, and techniques to counteract these errors have been developed and accumulated. Meanwhile, it has been reported that muons can also cause soft errors, raising concerns about their frequency of occurrence in cutting-edge devices. While muon irradiation experiments have been reported in recent years, negative muon irradiation to FinFETs has not been reported. Negative muons have the unique physical property of muon capture reaction, and generated secondary ions have larger linear energy transfer (LET) than muons themselves. We performed positive and negative muon irradiation experiments on 12-nm FinFET and 28-nm planar SRAMs at MUSE in J-PARC. This talk will introduce the obtained results and discuss the future research direction.

11:25 Talk 1: Single Event Effects (SEE) Testing in the United States: The Current State of Facility Access and Considerations Moving Forward

Abstract:

It has been well-documented that the aerospace community has had difficulty in obtaining sufficient access hours to perform SEE testing1. The increase in number of “small” and less risk-adverse projects and the associated rise in the use of electronics not necessarily designed for space utilization are primary factors for the limited hours available at SEE test sites being well over-subscribed.
In this presentation, we will discuss the current state of both heavy ion and proton facilities in the United States (U.S.) including current efforts to upgrade existing facilities (heavy ions) or gain additional access (protons).
The second half of the presentation will focus on additional considerations for the future needs for SEE testing focusing on four areas:
- Capability increases need: higher energy testing,
- Capability increases for fault identification: microbeam,
- The challenges of access and sustainment of proton medical sites in the U.S., and,
- The use of alternate means for SEE testing or increased SEE test efficiency.
These considerations are not new as seen in the figure below from 2012, but the ever-increasing hours needed have exacerbated the challenge2.

11:50 Talk 2: Landscape of European Facilities Delivering Protons and Heavy Ions: Status and Perspectives

Abstract:
Radiation hardness qualification procedures for electronic and microelectronic components as well as systems and boards often require testing at facilities – providing highly energetic protons, heavy ions, neutrons, electrons, gammas and to some extent pulsed X-rays, lasers, etc. – emulating the radiation effects of the devices under test close to reality. These probing radiations are generated mostly at particle accelerators or research reactors located almost exclusively at universities or publicly funded research institutions. Thus, users from industry as well as users from space agencies or academia are dependent on these institutions for providing them a fee-based service.

In recent decades, a variety of research facilities across Europe have opened their doors to external users, offering beam time at their accelerators and radiation probes. Certain facilities have developed professional services, providing regular beam time to commercial customers and academic users. This presentation will highlight European irradiation facilities that provide high-energy protons and heavy ions, showcasing established sites for standard device qualification and radiation hardness assurance. Over half of the facilities in the RADNEXT1 consortium offer either heavy ions or protons, and we will present an overview of their key technical parameters. Some facilities boast unique technical capabilities, suitable for non-standard applications or R&D challenges in radiation effects.

The landscape of these facilities is dynamic, with some closing permanently and others beginning operations. Additionally, many irradiation facilities are planning upgrades to enhance their technical capacities, such as increasing fluxes or energies to better meet user requirements. Existing facilities are also evaluating the expansion of their service provision, i.e. offering more beam time hours for radiation hardness testing. Furthermore, some proton therapy facilities that previously did not offer beam time to external users are now considering starting this service. This presentation aims to provide a concise overview of the current changes and activities in this field.

12:10 Talk 3: The experience of HollandPTC in setting up a radiation hardness test facility

Abstract:

HollandPTC is a proton therapy facility for patient treatments and research located in Delft, The Netherlands. HollandPTC has a dedicated R&D proton beamline for preclinical research. In this presentation, we summarize how an experimental setup for radiation hardness tests was integrated in our R&D proton beamline. In 2021, in collaboration with ESA, the beamline was equipped, characterized and prepared to perform radiation hardness tests for space applications. The main requirement for building such a setup was to have a proton beam that met the standards for SEE tests in terms of energy and fluxes. In this context, beam energies of 70, 120, and 200 MeV were characterized for both pencil beam and broad beams with different fluxes, matching the needs for SEE tests on EEE components and boards. Broad beams are produced with a passive scattering system, for 2 different squared sizes 4x4cm2 and 10x10cm2, with a uniformity between 90% and 98% and beam flux between 4.6x104 and 2.1x108 p/s/cm2. A target station with motorized stages in x-y direction (beam direction along z-axis) has been realized with a standard board mounting provided by ESA, which is positioned in a unique isocenter where the switch between pencil beam and broad beam can be performed within 10-15 minutes.
In additional to the technical aspects, we will address challenges related to setting up a facility for hardness tests in a clinical environment, including: managing capacity of beam time and personnel, distribution of beam time hours among HollandPTC research consortium partners and space applications, implementing beam time application procedure for users, and establishing of cost rates.
Since 2022, HollandPTC successfully hosted multiple groups both from ESA and private companies in the space field, to perform radiation hardness tests.

12:30 Talk 4: Prospects of proton and ion microbeams for radiation hardness testing

Abstract:

Proton and heavy ion microprobes with beam sizes of 1 µm or less offer unique possibilities for radiation hardness testing. Using a microbeam at low count rate (10 to 1000 s-1), individual effects of single particles can be separated and correlated with the actual position of the beam. By scanning the beam across a microstructured sample the charge collection efficiency and/or damage sensitivity can be mapped and correlated to the device layout. As one example measured at the former ion microprobe SNAKE of the Maier Leibnitz Laboratory [1], heavy ion mapping of Single Event Effects (SEE) and Single Event Burnout (SEB) of super-junction power MOSFETs will be presented utilizing carbon ion micro-beams of 55 MeV [2, 3]. Charge collection efficiency depends on the position of the impinging carbon ions and on the range when changing the energy of the ions up to 55 MeV.
The tests require expertise in beam handling and data evaluation and the data analysis is more time consuming as conventional broad beam irradiations. A major drawback of using microbeams for radiation hardness testing is that only a few of the worldwide available microprobes offer heavy ion beams of sufficient range. An alternative to heavy ion microbeams is proposed using pulsed proton microbeams that allow the deposition of hundreds or even thousands of MeV protons in a single bunch of nanosecond length [4] as a substitute of single high energy heavy ions. By adjusting the number of protons in a single bunch, the total LET of the bunch can be adjusted from low LET (< 0.1 MeV/(mg/cm²)) for single protons of some MeV up to 100 MeV/(mg/cm²) when bunching thousands of these protons in a single bunch. This would allow the use of many more of the MeV proton microprobes but requires challenging effort of proton sources and beam pulsing equipment to obtain the high number of protons in a single bunch.

14:15 Talk 1: Investigation of Fundamental Mechanisms of Single Event Effects with Heavy-Ion Microbeam Testing

Abstract:

Heavy-ion microbeam testing offers unique capabilities for exploring the fundamental mechanisms of single-event effects (SEEs) in electronic devices. This method utilizes a beam focused to a diameter of less than 1 µm to irradiate specific regions on the surface of the device selected by an optical microscope directly installed in the vacuum chamber.
The dimensions of the scanned area, the number of total ions, and the distance among them are adjustable, enabling micron-accurate localization of radiation-sensitive regions. This level of spatial resolution surpasses that of broad-beam testing, providing invaluable insights for a deeper understanding of the basic mechanisms of SEEs.
This presentation introduces commonly used microbeam testing facilities, discussing both the benefits and challenges associated with this methodology [1-3]. Essential considerations for users regarding setup and testing procedures are also compared to those of standard broad-beam testing with heavy ions.
As a case study, the results of microbeam testing on SiC power devices are presented, demonstrating the effectiveness of this methodology in exploring SEEs [4]. Furthermore, the discussion extends to the relevance and applicability of the microbeam testing across various electronic components.

14:35 Talk 2: So, you need to do a proton test and have no clue why or how

Abstract:

This talk tries to give answers to the following questions of less experienced people:
Why do I need to test with protons? What radiation effects are covered? When do I need a proton test and when are other particle types better (heavy ions, neutrons)? How do I need to prepare my device under test (DUT)? What is the relevant dosimetry? What flux and fluence do I need for which effect? What is NIEL? What about radiation protection (I am scared already)? What limits my test setup? Can I take my DUTs and measuring equipment back home with me?

14:55 Talk 3: What New Space wants from radiation testing facilities

Abstract:

New Space companies vary in radiation testing approaches. New ventures prioritize rapid deployment and initial operation phases to secure further funding, while mature companies face customer demands for some level of radiation risk mitigation without the full cost of a "rad hard" approach. There is frustration over the high costs, resource demands, and lack of clear guidelines for short-term missions or less intensive testing options. Companies seek affordable, fast testing facilities with broad capabilities, favoring local options. Future desires include easier access to heavy ion testing, guidance for companies with higher radiation risk tolerance, and standards for both board level and alternative testing methods.

15:35 Talk 5: Radiation hardness testing (SEE): Challenges and Perspectives

Abstract:

Space market evolution towards more flexible, agile and integrated systems, such as SmallSats or satellite constellations, is pushing the use of more complex EEE parts.
Newspace market particularly accelerated the introduction, in space units, of COTS devices, i.e. components not designed to endure space environment constraints, generating, in fact, a strong demand to evaluate parts behavior against radiation induced effects. Characterization of EEE parts against protons and heavy ions induced effects is indeed crucial for space systems.
The purpose of this talk is to give an overview of the current and future trends in EEE parts testing and related test methodology, highlighting the challenges we are facing with current facilities, including parts preparation, beam time availability, energies, etc., and to give some perspectives to meet these needs.
