research PMT Saturation and Suppression Characterization Bench measurements and circuit simulation of nonlinear PMT-base response for PandaX-xT. PMT Signal Acquisition and Characterization A 192-channel test platform linking waveform acquisition, calibration, and batch PMT evaluation. PMT Large-Signal Response and Waveform Correction Measured PMT response, coupled transport and circuit modeling, and correction of detector waveforms. Full-Chain Diagnostics of a 1408-Channel TPC Readout System Led three students in channel-level diagnostics and built a database for shared measurements and fault tracking. Rigid-Flex PMT Base Evaluation Thermal and electrical characterization of rigid-flex PMT bases, informing signal-routing improvements. 55-Channel R11410 PMT Readout Array Designed and implemented a multi-channel PMT readout system for a 55-PMT array, including waveform acquisition, baseline correction, and charge extraction. Light Source Position Reconstruction with PMT Arrays Implemented position reconstruction algorithms based on PMT charge distributions, including center-of-gravity and PAF methods, and evaluated spatial resolution. ROOT-based PMT Waveform Analysis Framework Developed a C++/ROOT pipeline for multi-channel waveform processing, including baseline subtraction, peak finding, charge integration, and automated fitting. outreach Cycling Injury Workshop and Sports Outreach Organized and delivered a workshop on identifying and managing cycling-related knee injuries, integrating biomechanics with practical training guidance. First Cycling Race at Jilin University Organized the first campus-wide cycling race, including planning, safety management, and on-site execution.
