Abstract

The Accelerator Driven Subcritical System (ADS), using proton beam hitting on the target to produce neutron for spending fuel stable increment or accelerating evolution, aims at finding key solutions for nuclear fuel stable provision and for the safe nuclear waste treatment. The injector I and the main linac will be designed and fabricated by IHEP. The RF power source system provides 325 MHz continuous wave power for RFQ cavity of ADS injector I and beam energy reaches several MeV through RFQ cavity. RF power source system includes 600 kW continuous wave klystron, 80 kV/18 A PSM power supply based on pulsed step modulation techniques, circulator and corresponding waveguide transmission system for ADS injector I. According to the overall design for ADS system and RFQ technical parameters, overall layout, technical specifications and design requirements of RF power source system are proposed, equipment installation and commissioning are carried out, and the system has passed the expert acceptance testing. ©, 2015, Editorial Office of High Power Laser and Particle Beams.
