Until recently, it was thought that the proton radius was known with an uncertainty of 1%. However, experiments at the Paul Scherrer Institute (PSI) involving muonic hydrogen yielded a radius 4% smaller with an uncertainty of .1%, a 7.9σ inconsistency. This problem of properly measuring the radius now requires new and different measurements. The MUon proton Scattering Experiment (MUSE), carried-out at PSI, Switzerland, will thus be the first to utilize elastic muon proton scattering with sufficient precision to address the Proton Radius Puzzle: incompatible measurements of the radius of the proton from electron-based and muon-based measurements. This project involves the integration of Straw Tube Tracking (STT) and Silicon Photomultiplier (SiPM) detectors into MUSE. STT development takes place at Hebrew University of Jerusalem (HUJI) while SiPM development takes place at PSI. The goal of my work was to establish an adjustable gas mixing system for STT detectors, become more familiar with the SiPM detectors, test new frames for detector assembly, and help with various other projects related to SiPMs and data readout. The results of this work are presented and discussed.
