Peiyuan Chen

I am an undergraduate student and research assistant in the PandaX Collaboration, focusing on experimental particle physics and detector instrumentation.

My research centers on liquid xenon time projection chamber (LXe TPC) technology, with particular emphasis on photomultiplier tube (PMT) readout systems, waveform analysis, and detector response characterization. I am actively involved in developing data processing pipelines and studying signal reconstruction methods for rare-event searches.

I have experience working with ROOT and C++ for waveform analysis, including baseline subtraction, charge integration, and statistical modeling. My work also involves Python-based data analysis and visualization, as well as detector-level performance studies such as gain calibration, linearity, and saturation behavior.

Currently, I am working on PMT array readout systems and position reconstruction algorithms based on charge distribution in multi-channel detector configurations, motivated by applications in dark matter detection experiments.
