JAEA/J-PARC, Tokai-Mura, Naka-Gun, Ibaraki-Ken
The accelerator facilities in J-PARC have been commissioned since January 2007. According to the progress of beam commissioning and construction of accelerators and experimental facilities, operational beam power becomes larger. The RCS produces 120kW beam to MLF and the MR provides 50kW beam to Neutrino target. In such high intensity operation, Linac ACS section, RCS injection and arc section, and MR collimator section become slightly higher residual dose area. We try to improve these losses before it is too late.
