Ionization cooling is a new rapid beam-cooling technique, particularly important for muon accelerators due to the short lifetime of the particle. The Muon Ionization Cooling Experiment (MICE) is a multi-national accelerator physics experiment built to demonstrate IC. The amount of cooling
achieved depends on two key processes — energy loss due to collisional ionization, and Multiple Coulomb Scattering (MCS) — for which accurate models are crucial in enabling quantitative design studies for future muon accelerators. Experimental measurements of MCS of positive muons with momentum in the range 170–240 MeV/c through liquid-hydrogen are reported in this study.
