Cryogenic moderator Laser Ionization method
Slow muon beam Slow muons muons which are (re-)accelerated from the muons which are almost at a rest. Beam energy is tunable,and its spread is very small. The range in the material is tunable down to sub um. Emittance is very small. Small sample can be used. polarized muons ideal as a microscopic magnetic probe to solid state physics(uSR technique) ● Depolarization of the muon spin due to local magnetic fields can be monitored through decay positrons which are emitted preferentially along the spin direction
