At KEK an electron test beam facility with beam momentum up to 5 GeV has been established since 2022. Usually the beam is available for sensor testing for three periods (May-June, Oct-Dec and Feb-Mar) in each year in total about 5.5 months. The beam rate at 3 GeV is more than 2 kHz with beam spot size of 2 cm (1 cm) in horizontal (vertical) direction in RMS.
We have a plan to improve the...
We present the updated analysis of the fluence profile at the JSI TRIGA neutron reactor facility in Ljubljana. For the study, multi-pad Low-Gain Avalanche Diodes (LGADs) are used. The deactivation of acceptor doping in the gain layer implant due to the irradiation, typical of LGAD devices, is exploited to map the fluence profile inside the irradiation channels. The amount of active doping of...
The recent rise of fast timing applications at high radiation fluences requires testing in low-temperature environments (< -40°C) to mitigate thermal runaway for multi-pixelated matrices bonded to readout ASICs and to regulate carrier mobility. To that end, we present an upgraded infrastructure for the EUDAQ-based AIDA telescope at the SPS North Area H6B beamline. The system integrates a 1.2...
Semiconductor radiation detectors intended to be used in future accelerator facilities have often very specific requirements in terms of radiation hardness, spectroscopic quality, timing properties and spatial sensitivity. The ion microprobe technique IBIC (Ion Beam Induced Charge) is a well-established technique which provides information about most of these detector properties in a rather...
EURO-LABS is an EU project covering nuclear and particle physics (accelerator and detector) research infrastructures (RI). For HEP detector R&D, Transnational Access (TA) at 11 RIs is offered free of charge to the users.
I will review the usage at the RIs in the first two years of the project and point to opportunities for DRD3 projects to access the resources in the final two years,...
The qualification of new detectors in laboratory or test beam environments presents a complex challenge, requiring the stable operation of multiple devices often supported by separate control and data acquisition systems. These setups frequently undergo modifications, such as the inclusion of different reference detectors depending on the facility, adding further complexity. Successfully...
We propose to combine two existing DAQ programs: Track Lab and Constellation. Track Lab is a graphical application focusing on pixel detectors of the Timepix family, compatible with a diverse range of readout hardware such as Katherine and MiniPIX. Thanks to its modular architecture, Track Lab allows users to construct complex data processing workflows by interconnecting simple building...
A beam telescope based on the Timepix4 ASIC was built in order to perform tests of synchronous multiple-detector readout and track reconstruction with fast timing capability. The beam telescope is an excellent tool to study novel sensors with both high spatial and time resolution, and is capable of operating at high rates. The Timepix4 is a readout ASIC for hybrid pixel detectors that is...
We demonstrate the application of the Three-Photon Absorption Transient Current Technique (3PA-TCT) for the characterization of silicon carbide (SiC) p-in-n diodes with an active thickness of 50 µm, manufactured at IMB-CNM. The characterization was performed at the laser facility of the University of the Basque Country (UPV-EHU), utilizing advanced nonlinear optical techniques to achieve...
OBELIX will be the next chip in the succession line of the TJ-Monopix family. Implemented in Tower Semiconductor 180 nm technology, with its small pixel pitch (33 um2) and fast time precision (100 ns), OBELIX is designed targeting the vertex and tracker detectors for future e+e- collider experiments. In this contribution a first OBELIX-based telescope system will be proposed as possible...
