Tracking and Event Visualization for the Muon Proton Scattering Experiment*

In 2010 the proton radius was measured to be 0.842 fm ± 0.001 fm, which is approximately 4 % smaller than the previously accepted CODATA value determined from electronic measurements. The Muon Proton Scattering Experiment (MUSE) is seeking to shed light on this so called "Proton Radius Puzzle" by simultaneously scattering electrons and muons off of a liquid hydrogen target at the PiM1 Beamline in the Paul Scherrer Institute. Scattered particles are measured in the Straw Tube Tracker. Tracks are formed in offline analysis, but for near-online analysis an event display is under development to quickly assess the operation of the STT. In this poster we will discuss the STT tracking efficiency and demonstrate the operation of the event display.
