Description
Particle magnetic spectrometers are essential instruments in particle physics, enabling precise measurements of the momentum, charge, time of flight, and energy of charged particles. Driven by the requirements of next-generation magnetic spectrometer experiments, the project team focuses on key technologies for high-precision semiconductor tracking detectors. The project advances the development and engineering validation of high-performance silicon- and SiC-based detectors, dedicated readout electronics, high-speed data acquisition, lightweight mechanical structures, and low-temperature cooling systems. A major objective is to develop a large-area semiconductor sensor capable of simultaneously achieving a timing resolution better than 40 ps and a spatial resolution of approximately 10 μm. In parallel, a dedicated readout ASIC featuring high precision, low power consumption, and high integration density is being developed, together with a radiation-tolerant RISC-V system-on-chip (SoC) for high-energy physics applications, enabling dynamic front-end configuration, on-chip intelligent algorithms, and data processing.
The project also includes the development of high-speed data acquisition systems, low-mass, high-strength carbon-fiber support structures, and the first two-phase CO₂ cooling system for semiconductor detectors in China. These technologies will be integrated into engineering prototypes for system-level validation. Ultimately, the team aims to establish an integrated R&D framework covering the entire technology chain—from sensors and electronics to readout, mechanics, cooling, and system integration—providing a technological foundation for next-generation ground-based colliders, space-borne magnetic spectrometers, and high-precision radiation detection systems. In this talk, we will present an overview of recent detector R&D progress, system integration, and future development plans.
