The Liquid Hydrogen Target for MUSE

The Muon Scattering Experiment (MUSE) at the Paul Scherrer Institute aims to measure the elastic scattering of muons and electrons from a liquid hydrogen target in order to work towards resolving the proton radius puzzle. MUSE will perform the scattering of both lepton families simultaneously, and both charge variants sequentially, determining the scattering cross section in each case with high precision. To accomplish this goal, MUSE employs a vertically movable target with five different target positions respective to the proton beam. The main target is a cylindrical Kapton cell with copper end caps that holds 280 mL of liquid hydrogen. In this presentation, we discuss the technical design, implementation, and performance of the target system and its support infrastructure, presenting data to demonstrate the successful operation of the LH$_{\mathrm{2}}$ target. Additionally, we remark on the recent improvement efforts for the target system.
