        The search for gravitational waves from LIGO/Virgo/KAGRA detectors to Einstein Telescope: recent results and new frontiers of gravitational wave instruments and astronomy 45m

        Einstein Telescope is the future European Laboratory for gravitational waves. The discovery of gravitational waves (GW), in 2015, 100 years after the publication of Einstein’s general theory of relativity, was soon followed, in 2017, by the assignment of the Nobel prize for physics to three scientists of the LIGO-VIRGO collaboration. LIGO in the USA and VIRGO in Italy are, at present, the unique detectors worldwide capable to observe the GW signals. In 2017 with a coordinated effort of LIGO-VIRGO and a network of Telescopes on earth and in the space the gravitational waves signal from a neutron star collision was detected and combined with its electromagnetic counterpart, opening the era of multi messenger astronomy.

        This provided the substantial momentum which led to the proposal of a third generation GW detector in Europe. In July 2021 Einstein Telescope was officially approved and inserted in the ESFRI program. The detector will substantially improve the current ones in sensitivity and in background suppression. In the present configuration it is designed as a triangle, underground, of 10 km per side, but a twin L shape system, with same concept of the LIGO detector is under consideration, There are presently two site candidates, one in Italy, in Sardinia, and one in the Netherlands, in the Limburg region.

        This presentation will cover both the genesis of the project and the principles of GW detection, its technological challenges and an overview of the present status and future schedule.

        Sardinia cultural heritage: the nuraghi and nuragic civilization 45m

        Sardinia has an age old history told by a great cultural heritage and the nuraghi are probably the most important archaeological and cultural evidence. These majestic stone towers, built in the second millennium B.C., have represented a long term landscape marker and a symbolic reference point for Sardinian communities. Extraordinary ancient architects designed and built at least 7000 monumental buildings all over the island, big stone towers that were symble and centre of life of a great civilization. Sardinia territory still preserves many other archaeological evidences of this great people life, such as monumental tombs (giant's tombs), temples as sacred wells, sanctuaries, villages and an important bronze artifact production (axes, swords, figurines, ecc.). Nuragic people controlled the whole island from North to South, but were also involved in the main sea routes and traffics of the Mediterranean sea. Nuragic finds in Cyprus, Crete, Sicily, Spain, Northern Africa show us the important role of this civilization in the Mediterranean Bronze and Iron age trades and networks.

        Performance of H2GCROC3, the readout ASIC of SiPMs for the back hadronic sections of the CMS High Granularity Calorimeter. 20m

        H2GCROC is the 130nm CMOS ASIC designed to read out the SiPMs coupled to the scintillating tiles of the back hadronic sections of CMS HGCAL (High Granularity Calorimeter). Each of its 72 channels is composed of a current conveyor, a high-gain preamplifier, a shaper, and ADC to read the energy, with two discriminators connected to TDCs for time-of-arrival and time-over-threshold information, respectively. This work presents the ASIC architecture and its characterization in lab and test beam, proving good adaptability in calibration, radiation tolerance, capacity to measure SiPM SPS (single-photon-spectrum), MIP's time and energy with high resolution.

        First test results for ECON-T and ECON-D ASICs for CMS HGCAL 20m

        With over 6 million channels, the High Granularity Calorimeter for the CMS HL-LHC upgrade presents a unique data challenge. The ECON ASICs provide a critical stage of on-detector data compression and selection for the trigger path (ECON-T) and data acquisition path (ECON-D) of the HGCAL. The ASICs, fabricated in 65nm CMOS, are radiation tolerant (200 Mrad) with low power consumption (<2.5 mW/channel). We report the first functionality and radiation tests for the ECON-D-P1 full-functionality prototype including a comparison of single event effect (SEE) cross sections measured for different methods of triple modular redundancy.

        Testing and characterisation of the prototype readout chip for the High-Luminosity LHC upgrade of the CMS Inner Tracker 20m

        This talk describes the characterisation and validation campaign of the prototype of the CMS Readout Chip (CROC), a 65 nm CMOS pixel readout ASIC for the CMS Inner Tracker upgrade for High Luminosity LHC. This validation campaign includes tests with single-chip and multi-chip modules, irradiation campaigns, test beams and wafer-level tests. The main results obtained in the testing of the CROC prototype will be outlined. Key improvements and fixes that have been implemented in the final version of the chip before the summer 2023 submission will be described.

        CMS Level-1 trigger Data Scouting firmware prototyping for LHC Run-3 and CMS Phase-2 20m

        A novel Data Acquisition (DAQ) system, known as Level-1 Data Scouting (L1DS), is being introduced as part of the Level-1 (L1) trigger of the CMS experiment. The L1DS system will receive the L1 intermediate primitives from the CMS Phase-2 L1 trigger on the DAQ-800 custom boards, designed for the Phase-2 central DAQ. Firmware is being developed for this purpose on the Xilinx VCU128 board, with features similar to one half of the DAQ-800, and validated in a demonstrator for LHC Run-3. This contribution describes the firmware development in view of the target design for the DAQ-800.

        Time and Clock Distribution Over a Hierarchy of Deterministic Optical Links 20m

        Accurate clock and time distribution is a key requirement for self-triggered streaming data acquisition in the CBM experiment. This distribution is handled by the Timing and Fast Control (TFC) system by clock forwarding and broadcasting the common time over latency-deterministic optical links in a hierarchical FPGA network. The point-to-point optical connections are served by the latency-optimized GBT-FPGA core, which has been developed at CERN. In the presented work, the performance of GBT-FPGA links for time and clock distribution in a scaled TFC system with multiple hops and endpoints has been investigated.

        A demonstrator for a real-time AI-FPGA-based triggering system for sPHENIX at RHIC 20m

        The RHIC interaction rate at sPHENIX reaches around 3 MHz in pp collisions and requires the detector readout to reject events by a factor of over 200. Critical measurements often require the analysis of particles produced at low momentum. This prohibits adopting the traditional approach, where data rates are reduced through triggering on rare high momentum probes. We propose a new approach based on real-time AI technology, adopt an FPGA-based implementation using a FELIX-712 board with the Xilinx Kintex Ultrascale FPGA, and deploy the system in the detector readout electronics loop for real-time trigger decision.

        Design and characterization of RD53C production chips for ATLAS and CMS pixel upgrades at HL-LHC 20m

        The RD53 Collaboration, established in 2013 as a joint effort between ATLAS and CMS pixel ASIC communities on 65nm CMOS technology, is now in the phase of implementing final pixel readout chips, referred to as RD53C revisions, that will be used into upgraded pixel detectors at HL-LHC. The purpose of this work is to provide a comprehensive review of most important architectural design choices, enhancements, implementation details and verification flows adopted to submit final ATLAS and CMS production chips, along with preliminary test results and measurements.

        Performance of the COLUTA ADC ASIC for the ATLAS HL-LHC Liquid Argon Calorimeter Readout 20m

        The COLUTA ASIC is an 8-channel 15-bit 40 MSPS ADC fabricated in 65 nm CMOS for the upgrade of the readout of the ATLAS LAr calorimeter for the high luminosity LHC. The ADC architecture couples a 3.5-bit Multiplying-DAC (MDAC) stage to a successive approximation register (SAR) ADC with a digital back-end that outputs sample data continuously via 640 Mbps serial LVDS. The analog performance and radiation tolerance tests and measurements of the production COLUTA ADC will be presented, along with the robotic multi-chip test setup and procedures developed for the verification of 80,000 COLUTA ADC ASICs.

        Chips for calibration of the ATLAS LAr calorimeter 20m

        The LHC upgrade requires redoing the LAr calibration system which should provide a 16-bit range signal with 1‰ accuracy while being radiation tolerant. The former operating principle is used: a precise current is stored in an inductor, when it is switched off, a pulse is generated to be injected in the readout electronics. This is achieved by two chips: the first one, in TSMC 130nm, provides the 16-bit DAC as well as the calibration management system; the second one, in XFAB 180nm, embeds switches to generate the pulses. A description of both chips and measurement results will be presented.

        Testing a Neural Network for Anomaly Detection in the CMS Global Trigger test crate during Run 3 20m

        We present the deployment and testing of an autoencoder trained for unbiased detection of new physics signatures in the CMS Global Trigger test crate during LHC Run 3. The GT test crate is a copy of the main GT system, receiving the same input data, but whose output is not used to trigger the readout of CMS, providing a platform for thorough testing of new trigger algorithms on live data, but without interrupting data taking. We describe the integration of the DNN into the GT test crate, and the monitoring, testing, and validation of the algorithm during proton collisions.

        Real time data processing with FPGAs at LHCb 20m

        During the LHC Run-3 the LHCb software trigger is expected to reconstruct events at an average rate of 30 MHz. In view of future runs at even higher luminosities, LHCb established a testbed for new heterogeneous computing solutions for real-time event reconstruction within the current DAQ infrastructure. The most advanced of these sois a highly-parallelized custom tracking processor (“Artificial Retina”), implemented in state of the art FPGA devices connected by fast serial links. We describe the status of the development of a life-size demonstrator system for the reconstruction of pixel tracking detectors, that will run on real data during Run-3.

        During the next LHC Long Shutdown, the innermost three layers of the ALICE Inner Tracking System will be replaced by a new vertex detector composed of curved ultra-thin monolithic silicon sensors. The R&D initiative on monolithic sensors of the CERN Experimental Physics Department, in synergy with ALICE ITS3 upgrade project, prepared the first submission of chip designs in the TPSCo 65 nm technology, called MLR1. It contains four different test structures: CE-65, DPTS, APTS-SF and APTS-OPAMP, with different process splits and pixel designs. This work illustrates the validation of the technology in terms of pixel performance and radiation hardness.

        Model and analysis of the data readout architecture for the ITS3 ALICE Inner Tracker System 20m

        The ALICE collaboration is developing the new Inner Tracker System 3 (ITS3), a novel detector that exploits the stitching technique to construct single-die monolithic pixel sensors of up-to 266 mm x 93 mm. ITS3 requires all hits from a particle flux of 4.4 MHz/cm2 to be transmitted on-chip to one of the sensor edges. This on-chip readout is limited by a power budget of 20 mW/cm2, a readout inefficiency of <2.5×10−3 and ≤10 % dead area. The model of ITS3 on-chip readout architecture will be presented, used to optimize the data flow implementation limited by physical and power budget constraints.

The Multi-Voltage Thresholding (MVT) approach can replace to some extent an external ADC with internal resources of an FPGA, thus reducing costs and complexity. The MVT approach needs only a few low-cost external components. The focus of the talk is presenting an open-source IP-Core that implements the MVT approach and simplifies implementation on a standard FPGA. The talk also provides an overview of characterization measurements and specific calibration methods. Our example application demonstrates the viability of the developed IP-Core for signal acquisition from multiple SiPMs.

Test beams employing the current ALICE Alpide chips, bent to foreseen ITS3 radii, showed that MAPs remain fully functional. However, some electrical effects, like (PS) power supply current changes and voltage shifts, were observed. The results suggest that these are caused by “piezo resistive effect” and FET threshold shifts, probably occurring in the pixel transistors. Some design architectures showed to be less susceptible to these effects and detailed investigations could help in design optimization. This contribution discusses latest test results.

        RDMA communication is an efficient choice for many applications, such as data acquisition systems, data center networking and any other networking application where high bandwidth and low latency are necessary. RDMA can be implemented using a large array of options which need to be tailored to the needed use case in order to get optimal results. Aspects such as the effects of using multiple simultaneous connections, using various transport functions such as RDMA Write and RDMA Send and communication models such as sending individual bursts or continuous streams of data will be investigated for implementing RDMA on FPGA devices.

It is based on a positive feedback topology using regular CMOS transistors with zero static current, rather than constantly drawing current in typical discriminators. When a small charge is injected at the input, the circuit flips rapidly due to the positive feedback and output a logic transition for further digitization. Simulation shows that in 65 nm process, it is capable of detecting at a threshold of 5 fC while maintain the average power consumption below 10 micro-Watts when the hit occupancy is <10% for 40MHz operation.

        In-pixel AI for lossy data compression at source for X-ray detectors 20m

        This work introduces AI-In-Pixel-65, an ROIC test chip designed for pixelated X-ray detectors using a 65nm Low Power CMOS process. The study compares two data compression techniques, Principal Component Analysis (PCA) and AutoEncoder (AE), implemented within the chip's pixelated area to address I/O bottlenecks. Our design methodology utilizes high-level synthesis (HLS) and hls4ml, offering shorter design cycles and similar quality results compared to register-transfer level (RTL) flows. Results show PCA achieves 50-fold compression with a 21% pixel area increase, while AE offers 70-fold compression and similar area increase.

        A simulation methodology for establishing IR-drop-induced clock jitter for high precision timing ASICs. 20m

        The combination of 3D tracking and high-precision timing measurements has been identified by the European Committee for Future Accelerators as a fundamental requirement to increase detection capabilities for future applications. Among others, on-chip high-quality clock is a key factor determining the overall resolution of Timing ASICs. However, in large and dense chips, power-grid drops can severely affect the non-deterministic jitter of the clock, representing a limit to the performances. This contribution aims at presenting a simulation framework based on commercial tools to evaluate power supply-induced jitter, providing a pre-silicon methodology to assess its impact on timing indeterminism.

        Prototyping during pre-production: the re-design of ATLAS ITk strip tracker powerboards for the end-cap 20m

        For the construction of the future ATLAS strip tracker end-caps, six geometries of silicon strip detector modules were designed. Each module comprises one or two silicon strip sensors and several flexes holding the required readout electronics, designed to match the geometry of each module. Due to the large number of designs, two module geometries using two sensors per ring module were prototyped for the first time in 2022, and showed excessively high noise. This contribution presents an overview of the follow-up investigation to diagnose the issue, the subsequent powerboard re-design and results from the first prototypes in 2023.

        Advancing fusion energy: Meeting the challenges of diagnostics and electronics for the ITER project 45m

        In the pursuit of clean and sustainable energy, the International Thermonuclear Experimental Reactor (ITER) project has emerged as a beacon of hope. As the world's largest experimental fusion reactor, ITER aims to demonstrate the feasibility of fusion as a viable energy source. However, operating in a challenging nuclear environment presents numerous technical and engineering obstacles that must be overcome to ensure safe and reliable operation.
        The diagnostic systems are critical to the successful and safe operation of ITER. They provide the means to observe, monitor and maintain plasma performance over extended periods of time. They provide accurate measurements of plasma behaviour and performance, including those required for protection of the machine and its control, as well as measurements required for physics studies. In total, about 50 diagnostic systems will be installed on ITER.
        This presentation focuses on the development of diagnostics systems and the utilization of electronics within the ITER project. The harsh environment, characterized by high temperatures, intense neutron fluxes, and strong magnetic fields, poses significant challenges for electronics and instrumentation.
        The first part of the presentation discusses the design and development of diagnostic systems for ITER. These systems encompass a wide range of measurements, including plasma temperature, density, and impurity content.
        The second part of the presentation delves into the unique requirements and challenges associated with electronics used in the nuclear environment of ITER. The radiation effects, including total ionizing dose, displacement damage, and single-event effects, pose serious reliability concerns for electronic components. Radiation-hardened designs, materials, and techniques are discussed, along with strategies for mitigating radiation-induced failures and ensuring the longevity of electronic systems.
        Finally, this presentation provides an overview of the research and development efforts underway in the field of diagnostics and electronics as part of the ITER project. By addressing the technical challenges and presenting the progress made, it aims to encourage the exchange of knowledge, collaboration and innovation in the field of electronics for nuclear fusion. The knowledge gained from this research will not only contribute to the success of ITER, but will also pave the way for future advances in fusion energy technologies.

        How the discovery of Cold Noise delayed the production of ATLAS ITk strip tracker modules by a year 45m

        The construction of the ATLAS strip tracker barrel will require the assembly of 12,000 barrel detector modules over the course of 3.5 years. In 2022, during the module pre-production phase, modules were found to display clusters of noisy channels outside required specifications when tested at operating temperatures (-40 ºC), called “Cold Noise”. Extensive investigations into the cause and mechanism of Cold Noise interrupted pre-production and occupied most barrel module assembly sites. This contribution presents an overview of the year-long investigations into Cold Noise, the final identification of the underlying mechanism and necessary changes for the transition to production.

To efficiently acquire data from these sensors, the readout electronics operating at room temperature must perform multiple tasks, such as real-time frequency demodulation. We designed a Software-Defined Radio (SDR) system composed of an MPSoC board, an analog-to-digital conversion stage, and a radio frequency front-end mixing stage to meet the system requirements. Nevertheless, utilizing an Radio Frequency System-on-Chip (RFSoC) could simplify the overall system by integrating the conversion stage and potentially eliminating the mixing stage. This work investigates the applicability of RFSoCs for the aforementioned use case.

        A Low-Power Gated-Vernier Ring Oscillator TDC for Cryogenic Detectors 20m

        High-resolution time-to-digital converters (TDCs) are required for time-of-flight measurements in many applications, including particle identification for high-energy physics. FPGA-based TDCs are popular for such applications but suffer from limited resolution and high power consumption compared to custom ASICs. Full-custom TDC designs can also be integrated within multi-channel or pixelated front-end ASICs, thus eliminating power-hungry low-latency links to external FPGAs. Several applications for such integrated TDCs, such as photon time stamping in rare-event searches, also require cooled detectors and front-end electronics. Here we describe a full-custom TDC in 90nm CMOS technology designed for high-resolution and low-power operation in such cryogenic environments.

        The Optosystem: validation and testing of the high-speed optical-to-electrical conversion system for the readout of the ATLAS ITk Pixel upgrade 20m

        After Run III the ATLAS detector will undergo a series of upgrades to cope with the harsher radiation environment and increased number of proton interactions in the High Luminosity-LHC. One of the key projects in this suite of upgrades is the ATLAS Inner Tracker (ITk). The pixel detector of the ITk must be read out accurately and with extremely high rate. The Optosystem performs optical- to-electrical conversion of signals from the pixel modules. We present recent results related to the performance of the data transmission chain pivoted on the Optoboards and to the design, testing and production of the Optopanels.

        The End-of-Substructure (EoS) card for the ATLAS Strip Tracker Upgrade – from Design to Production 20m

        The ATLAS Strip Tracker for HL-LHC consists of individual modules that host silicon sensors and front-end electronics. The modules are then mounted on carbon-fiber substructures hosting up to 14 modules per side. An End-of-Substructure (EoS) card connects up to 28 data lines to the lpGBT and VL+ ASICs that provide data serialization and 10 GBit/s optical data transmission to the off-detector systems respectively. The EoS is powered by a dedicated Dual-Stage DC-DC converter. With the EoS now moving into production we report on first experiences from production and also give a few lessons learned during the project duration.

        The optimization, design and performance of the FBCM23 ASIC for the upgraded CMS beam monitoring system 20m

        We present the development of the FBCM23 ASIC designed for the Phase-II upgrade of the Fast Beam Condition Monitoring (FBCM) system built at the CMS experiment. The FBCM system should provide reliable luminosity measurement with 1ns time resolution enabling the detection of beam-induced background. The FBCM23 ASIC comprises six channels of fast preamplifier working in transimpedance configuration followed with CR-RC3 shaper and leading edge discriminator. The paper will show the optimization of the design, overall architecture and the detailed implementation in a CMOS 65nm process as well as preliminary electrical performance.

        The phase-1 upgrade of the ATLAS level-1 calorimeter trigger 20m

        The ATLAS level-1 calorimeter trigger is a custom-built hardware system
        that identifies events containing calorimeter-based physics objects,
        including electrons, photons, taus, jets, and missing transverse energy.
        In Run 3, L1Calo has been upgraded to process higher granularity
        input data. The new trigger, currently running in parallel with the
        legacy system, comprises several FPGA-based feature extractor modules,
        which process the new digital information from the calorimeters and
        execute more sophisticated trigger algorithms. The design of the
        system will be presented along with an analysis of the improved
        performance of the upgrade in the increasingly challenging Run-3
        LHC pile-up environment.

        The quality control programme for ITk strip tracker module assembly 20m

        The assembly of the ATLAS Inner Tracker requires the construction of 19,000 silicon strip sensor detector modules in eight different geometries. Modules will be assembled and tested at 31 institutes on four continents, from sensors, readout chips and flexes. In order to adhere to the module specifications defined for sufficient tracking performance, a rigorous programme of quality control and assurance was established to cover components at every stage of assembly. This contribution presents an overview of the QA/QC programme for ITk strip tracker modules, results from the pre-production phase (5% of the production volume) and proposed adjustments for production.

        Time-Delay-Based Analog Front-End for Monitored Drift Tubes in 65 nm CMOS with < 200 ns Baseline Recovery Time and Coherent Time-over-Threshold 20m

        Monitored Drift Tube (MDT) chambers for muons detection at ATLAS Experiment adopt analog front-end read-out electronics for precise-tracking/momentum measurements of detected particles [1]. State-of-the-art has historically used bipolar shaping electronics (at approximately 800 ns baseline recovery time [2]) that scarcely fits with High-Luminosity (HL) requirements where small-MDT (sMDT [3]) are used at 180 ns input signal time-width. This brief presents 4-channels Application Specified Integrated Circuit in 65 nm CMOS for sMDT signal amplification and shaping that performs < 200 ns baseline recovery time and avoids distortion of Time-over-Threshold (ToT) characteristic due to multiple close input charge pulses composing sMDT signal.

        Two HVCMOS active pixel ASIC designs for the Measuring GCR and SEP with a combined dynamic range of >80dB 20m

        The design of HVCMOS pixel detectors for measuring Galactic Cosmic Rays (GCR) and Solar Energetic Particles (SEP) in space is presented. The design goals are: (a) cover a very wide dynamic range (from ~0.5fC to pC) and (b) minimize the power consumption. Two pixel designs were implemented, one tailored to the measurement of high energy depositions due to impinging ions and one with high gain for the low energy depositions resulting from minimum ionizing particles. Both designs have been fabricated in the LFoundry 0.15μm technology. The design choices are backed by simulation results and preliminary measurements.

        Universal test system for boards hosting bPOL12V DC-DC converters. 20m

        ECAL Barrel (EB) and MTD Barrel Timing Layer (BTL) subdetectors of the CMS are approaching series production of electronic boards, including voltage conditioning PCBs: LVR and PCC respectively. 2448 LVRs and 864 PCCs will be installed during LS3 of the LHC. These boards are hosting radiation-tolerant bPOL12V ASICs which convert a broad input voltage range into required voltage levels for microelectronics between 1.2 – 2.5V. Each card must be tested multiple times at various production stages to ensure its quality. This contribution describes a methodology of testing bPOL12V conversion quality including the detection of instability regions at certain load levels.

        Design and performance of the front-end electronics of the charged particle detectors of PADME experiment 20m

        The PADME experiment at LNF-INFN employs positron-on-target-annihilation technique to search for new light particles. Crucial part of the experiment are the charged particle detectors, composed of plastic scintillator bars with light transmitted by wavelength shifting fibers to silicon photomultipliers (SiPM). The location of the detector – close to a turbomolecular pump, inside a vacuum tank, and exposed to 0.5 T magnetic field – has driven the design of custom modular SiPM front-end and power supply electronics. The design of the system and its performance, confirming the desired sub-ns resolution on the reconstructed particle times, will be shown and discussed.

        From 3D to 5D tracking: SMX ASIC-based Double-Sided Micro-Strip detectors for comprehensive space, time, and energy measurements 20m

        We present the recent development of a lightweight detector capable of accurate spatial, timing, and amplitude resolution of charged particles. The technology is based on double-sided double-metal p+-n-n+ micro-strip silicon sensors, ultra-light long aluminum-polyimide micro-cables for the analogue signal transfer, and a custom-developed SMX read-out ASIC capable of measurement of the time ($\Delta t\simeq 5\,\mathrm{ns}$) and amplitude. Dense detector integration enables material budget $>0.3\%,X_0$. The sophisticated powering and grounding keeps the noise under control.

        In addition to its primary application in Silicon Tracking System of the future CBM experiment in Darmstadt, our detector will be utilized in other research applications.

        The development of a laser system for use in the timing performance measurements of CMS HGCAL silicon modules 20m

        For optimal operations in the high radiation and pileup environment of the HL-LHC, the CMS-HGCAL requires precise timing information at the level of 30ps (RMS) for a particle shower. The time measurement in Silicon detector modules is performed using a per-channel time-of-arrival discriminator coupled with charge measurement to correct for the time-walk. The module design includes access holes in the PCB and in the sensor passivation to enable infrared laser light to be injected directly into the sensor cells. We present the calibration and timing-in of the system used to perform measurements as well as the module time performance results.

        Front End Board for Large Area SiPM Detector 20m

        Silicon photomultipliers (SiPMs) are widely used for several applications, such as High Energy Physics experiments, as well as other research and industrial fields. SiPMs working at low temperature, in particular, are the most interesting application for the newly large particle detectors for neutrinos and dark matter experiments. In this work we present a low-noise, high-speed front-end electronics (Front-End Boards, FEBs) for large area SiPMs to be used in the JUNO-TAO experiment. The FEBs are able to manage the signals coming from a 25 cm^2 tile, showing single photoelectron resolution better than 13% and dynamic range up to 250 p.e.

        Pioneering physics experiments require increasingly faster data transfers and high-throughput electronics, which drives the research towards a new class of serialisers and optical links. In this framework, the DART28, a $100\,Gbps$ radiation tolerant serialiser and driver, has been designed in $28\,nm$ CMOS technology and submitted in April 2023. The development has been coupled with an FPGA based emulation, which provided an early assessment of its behaviour, a scalable system-level demonstrator and an effective evaluation tool for compatible commercial solutions. The challenges faced in this research and the architecture of both the hardware setup and the firmware will be described.
