Abstract:
The large-scale detector spectrometer to be employed in the Super Tau-Charm Facility (STCF) will provide a 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.
