Fabrication and Testing of Tracking Detectors for MOLLER Experiment at JLab

The upcoming MOLLER experiment at JLab aims to measure the parity-violating asymmetry of longitudinally polarized electrons scattering off unpolarized electrons in a high power liquid Hydrogen target. This crucial measurement aims to enhance sensitivity in the search for new physics beyond the standard model. Gas Electron Multiplier (GEM) detectors will be utilized in this experiment to facilitate spectrometer calibration and background measurements. The design and fabrication of a fully functional prototype GEM detector module were successfully completed at the University of Virginia. The prototype module underwent testing for low rate environments with cosmic-ray particles and for high environments using X-rays with a CERN Scalable Readout System (SRS) readout system based on the APV-25 chip. Additionally, the module is undergoing testing with the experiment's DAQ system at JLab. Furthermore, track-based efficiencies will be obtained for the prototype module by operating it together with Super BigBite GEM tracker layers at JLab using cosmic particles. The findings of these performance tests will be presented.
