Our research group focuses on the experimental investigation of atmospheric cosmic ray muons using high-precision scintillation detection systems. By coupling plastic and liquid scintillators with fast photodetectors—including Silicon Photomultipliers (SiPMs) and Photomultiplier Tubes (PMTs)—and custom data acquisition (DAQ) architectures, we measure cosmic muon flux, angular trajectories, and secondary particle interactions. Our work integrates custom detector design, Monte Carlo simulation validation (such as Geant4), and signal processing, driving advancements in high-energy physics instrumentation, muography, and hands-on laboratory training.
