First demonstration of ionization cooling using the Muon Ionization Cooling Experiment Draft 1¶

Abstract¶

High brightness muon beams of energy comparable to state-of-the-art electron, proton and ion accelera-
tors have not yet been realised. Such beams have the potential to carry the search for new phenomena in
lepton-antilepton collisions to extremely high energy and provide uniquely well-characterised neutrino
beams. A muon beam may be created through the decay of pions produced in the interaction of a proton
beam with a target. To produce a high-brightness beam from such a source requires that the phase space
volume occupied by the muons be reduced (cooled). Ionization cooling is the novel technique by which it
is proposed to cool the beam. The Muon Ionization Cooling Experiment collaboration has constructed a
section of an ionization cooling cell and used it to provide the first observation of ionization cooling. We
present these pioneering measurements.
