	K. Yamada RIKEN Nishina Center, Wako, Japan
	The high-frequency systems for the RIKEN Ring Cyclotron (RRC) was upgraded in order to increase the acceleration voltage at 18.25 MHz operation by remodeling its cavity resonators and rf controllers. 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.
