Moderation of positive muons by helium gas
Journal of Physics: Conference Series, 2019 Abstract Efficiently creating beams of spin-polarized positive muons with energies between eV and keV (so-called slow muon beams) is important for further development and application of muon spin rotation, relaxation, and resonance techniques.

6D Muon Ionization Cooling with an Inverse Cyclotron
, 2005 A large admittance sector cyclotron filled with LiH wedges surrounded by helium or hydrogen gas is explored. Muons are cooled as they spiral adiabatically into a central swarm. As momentum approaches zero, the momentum spread also approaches zero.
