CONSTRUCTION OF RIKEN-RAL MUON FACILITY AT ISIS AND ADVANCED MU-SR

By utilizing the intense pulsed proton beam available at the ISIS faci lity of RAL, the new muon facility project of an advanced superconduct ing muon channel funded by the RIKEN is now under construction. The ne w facility, by adopting the superconducting solenoid system, will prod uce the strongest backward decay pulsed mu+ or mu- in the momentum ran ge from 20 MeV/c to 120 MeV/c. Also, by adopting the pulsed magnetic k icker, each one of two muon pulses will be supplied to two extraction channels simultaneously. Various important muon science experiments in cluding advanced pulsed mu- SR and mu+ SR experiments will be realized .
