MOLLER Gem Tracker Construction

The MOLLER experiment, which is set to start its run at Jefferson Labs in 2025, aims to use the measurement of parity-violating asymmetry to measure the weak mixing angle for a low energy at a precision of <1 part per billion. This precision will improve on the results of the SLAC E158 A_pv measurement and potentially give insight to physics beyond the Standard Model. One way this project plans to achieve this precision is using 4 planes of Gas Electron Multiplier Trackers to track individual particles during the calibration process. These detectors are comprised of 3 layers of GEM foils separated by thin frames with continuous gas flow in-between the foils, and a 4^th layer of a 2D readout board. In this presentation, I will discuss the main motivations for the GEM trackers and present on the construction and testing of these GEM Modules at Stony Brook University and report on the outgoing work and future plans.
