Tritium gas handling system for muon catalyzed fusion research at RIKEN-RAL muon facility

For muon catalyzed fusion (mu CF) experiments at RIKEN-RAL muon facility, a tritium gas handling system for a high purity D-T target, free from He-3 c omponent, has been constructed to perform precise measurements of alpha-sti cking probability in the mu CF cycle. The system has been constructed to en able us to purify the target D-T gas by removing He-3 component, to adjust the D/T mixing ratio, and to measure the hydrogen isotope components at the experiment site. The whole performance has been confirmed and a tritium ga s with the inventory of 56 TBq (1500 Ci) has been operated in the system.
