Refurbishment and reporting the current state of the vacuum system in the J-PARC RCS

Noshiroya, Shiyoji

In order to increase the beam intensity J-PARC 3GeV synchrotron at (RCS), it is necessary to uniform as much as possible the distribution of vacuum pressure, to further improve the vacuum. Since the beam loss is low where you have increased TMP temporary beam line to the RCS (L3BT) from the entrance portion to fiscal 2012, was expanded to two TMP exhaust system to the beam line in fiscal 2013. As a result beam loss has been reduced by 40% or more. RF1 section was added a new two as the same fiscal 2014. I have developed a mechanism that can be baked in a vacuum also kicker magnet further. I will introduce an overview.
