Abstract: While consistent results for the charge radius of the proton have been extracted from elastic electron-scattering data and through the spectroscopy of atomic hydrogen, recent high-precision studies of muonic hydrogen found notably smaller values for the charge radius. This so-called proton-radius puzzle raises questions ranging fromexperimental and methodological issues to physics beyond the Standard Model. The puzzle certainly calls for new measurements. The MUon Scattering Experiment (MUSE) at the Paul Scherrer Institute is being developed to provide elastic scattering data off the proton with electron and muon beams of positive and negative charge.Each of the four sets of data will allow the extraction of the proton charge radius; in combination,the data test possible differences of the electron and muon interactions and additionally two-photon exchange effects.The experiment will cover a four-momentum-transfer range from 0.002 to 0.07~GeV$^2$.
