As a result, the maximum gap voltage at 18.25 MHz improved from about 80 kV to more than 150 kV. The beam intensity of 238U for the RI Beam Factory was increased up to 117 pnA in the fiscal 2020 by overcoming the beam intensity limitation of RRC due to the space charge effect. In this talk, I will present the details of upgrade as well as the current status of high-frequency systems for the RRC.
