阻性微井型径迹探测器电子学原理样机的设计与实现

helarge-scaledetector spectrometer to be employedintheSuperTau-CharmFacility(STCF)willprovidea unique platform for cutting-edge particle physics research. Among its components, the cylindrical Resistive Micro-Well Inner Tracker (ITK), located at the core, is one of the key detectors for low-momentum particle trajectory reconstruction due to its low material budget, high counting rate, and excellent spatial resolution.This paper focuses on the physical requirements of the resistive micro-well detector and conducts research on critical technologies for readout electronics with high charge resolution. A highly integrated, high-performance 1024-channel readout electronics prototype has been developed. The system consists of ASIC readout units, front-end electronics boards, and data aggregation boards, featuring a rational and scalable architecture. Laboratory simulations and board-level tests demonstrate that the system functions as expected, with charge resolution and integral nonlinearity meeting specifications. These results provide strong technical support for further engineering development.
