Muon tomography offers a non-invasive imaging technique using the scattering of high-energy cosmic muons to reveal material properties. At SINP, a prototype muon tomography setup is currently being built, which includes a vertical stack of position-sensitive gaseous detectors that operate as muon trackers. This work focuses on the development and preliminary testing of a scintillator-SiPM-based detector prototype for its suitability in the current muon stack. Initial results demonstrate the feasibility of the prototype for efficient muon tracking and highlight possible optimization strategies to enhance detection efficiency. The study establishes the potential of hybrid detector systems for applications in non-destructive testing, border security, and nuclear material imaging.
