Timing Detectors with SiPM Read-out at MUSE

The MUon proton Scattering Experiment (MUSE) at the PiM1 beam line of the Paul Scherrer Institute works to simultaneously measure elastic scattering of electrons and muons from a liquid hydrogen target to extract the charge radius of the proton. Both beam polarities are measured over the course of the experiment. By comparing the four scattering cross sections, the experiment will provide unique muon proton scattering data with a precision sufficient to address the proton radius puzzle, and will directly measure two-photon exchange effects for both muons and electrons. Precise timing measurements, at the 100 ps level, are needed to identify particle and reaction types, and to measure beam momentum. I will discuss two scintillator detectors in the experiment that use silicon photomultiplier readout to achieve precise timing resolution. Recent analysis using these detectors will be presented.
