Description
National Central University and Academia Sinica have been developing a muography detector for geological exploration in Taiwan. The detector consists of four layers of plastic scintillators read out by silicon photomultiplier (SiPM) arrays, with a lead absorber to suppress electron background. A tree-structured, FPGA-based data acquisition (DAQ) system enables streaming readout and synchronized timing using a common reference clock, while front-end comparators provide signal discrimination. The detector was deployed in Daxi, where it measured the muon flux through Xizhou Mountain with stable operation over one year. A new measurement campaign targeting Qixing Mountain in the Datun Volcano Group is currently underway. This poster presents the development and performance of the muography detector and its FPGA-based DAQ system.
