Virtual prototyping of pixel detectors with PixESL framework in High Energy Physics
By Jashandeep Dhaliwal (CERN)
PixESL pioneers a virtual prototyping framework for future particle detectors in high-energy physics. Developed at CERN under the EP R&D Work-Package 5, this framework enables high-level abstraction, simulating the full detector chain from particle interaction to data packet readout. It facilitates early optimization of chip and system architecture, which is critical for meeting experiment specifications. PixESL models crucial components such as analog front-end, digital circuitry, and data readout networks, empowering designers to analyze interactions and optimize performance. Leveraging SystemC, PixESL offers rapid simulation runtime and above-RTL abstraction, presenting a pivotal tool for advancing particle detector design and verification.
Thermalisation of HTS-based current leads using a single-stage GM cryocooler
By Weronika Gluchowska (CERN & Wroclaw University of Science and Technology)
Cryocooler-based cooling technology promises compactness and modularity. Moreover, it allows for avoiding investment costs related to building large cryogenic plants. This makes it particularly attractive in the context of cooling future detector magnets for HEP experiments. Nevertheless, this technology features a modest cooling capacity which requires a dedicated design to reduce heat inleaks to the cold system. Current lead is a crucial component of a superconducting magnet because it connects it to the powering system but also transfers heat from ambient temperature to the cold mass. Therefore, a significant part of the heat has to be intercepted at an intermediate temperature level. This poster presents the design of 3kA HTS-based current leads for a Low-Temperature Superconductor detector magnet and the dedicated cooling system with a cryocooler. The leads are thermalized at 50K by helium gas circulating in a closed loop that operates with a single-stage Gifford-McMahon cryocooler and a cold circulator. Following the design and construction phases of the thermal exchangers, the demonstrator is currently being assembled and instrumented before the testing campaign starting next summer.
PICOSEC Micromegas precise-timing gaseous detectors and studies on robust photocathodes
By Marta Lisowska (CERN & Université Paris-Saclay)
The PICOSEC Micromegas (MM) detector is a precise-timing gaseous detector using a Cherenkov radiator, semi-transparent photocathode, and MM amplifying structure, aiming for a time resolution of tens of picoseconds for minimum ionising particles. Initial single-pad prototypes achieved a time resolution below 25 ps, prompting further development. The goal is to create robust multi-channel modules for large-area systems with excellent timing precision. Extensive R&D included simulations, design, production, assembly, and measurements in the lab and with 150 GeV/c muon beams. A significant advancement improved time resolution to 13 ps for a single-pad detector. A resistive PICOSEC MM with 20 MΩ/□ showed comparable results. Testing robust photocathodes like Diamond Like Carbon and Boron Carbide showed resolutions below 35 ps. A 100-channel detector with a 10×10 cm² active area demonstrated a resolution below 18 ps per pad, confirming design scalability. Integration of RF pulse amplifiers and a SAMPIC digitiser validated the system for multi-channel studies. These advancements make the PICOSEC MM concept feasible for large-area experiments requiring excellent timing precision.
