Description
"Silicon microstrip detectors offer precise position measurements and a modular architecture for charged-particle tracking and beam diagnostics. This report presents the development and testing of lightweight, low-cost silicon microstrip systems for testbeam facilities and cosmic-ray detection, covering both an existing silicon beam monitor and a compact detector system currently under development. The beam monitor has been tested with cosmic rays and operated in beam measurements at the High Energy Photon Source (HEPS). These studies provide practical experience in detector operation, signal acquisition, and data analysis, supporting the development of compact systems for broader laboratory and beam applications.
The new mini silicon microstrip system uses p-on-n sensors, each with 192 readout channels and a sensitive area of approximately 26 × 40 mm². Each module integrates three 64-channel IDE1140 front-end ASICs, dedicated bias and control circuits, and a compact mechanical support structure. The planned configuration comprises six modules arranged in three stations with orthogonal strip orientations, enabling two-dimensional position measurements and track reconstruction. A Xilinx ZCU102 FPGA-based data acquisition system supports front-end control, pedestal and noise calibration, programmable sampling delay, and internally or externally triggered acquisition.
Initial commissioning has been performed with individual modules biased at 50 V. Cosmic-ray measurements have revealed clear particle-induced hits and cluster signals, while sampling-delay scans demonstrate the dependence of signal amplitude on the readout timing. The report will discuss the detector and readout architecture, cosmic-ray and HEPS beam measurements with the existing beam monitor, and initial results from the mini system. Future development will focus on synchronized multi-module readout, track reconstruction, and beam-test validation."
