Development of RFQ power source for ADS injector I
-
摘要: ADS注入器Ⅰ高频四极场(RFQ)功率源系统将为325 MHz RFQ提供连续波功率,使束流离开RFQ时,其能量达到几MeV。功率源系统除了补偿RFQ腔耗外,还必须提供足够的功率以保证RFQ中的加速电场。ADS注入器Ⅰ RFQ功率源系统主要包括600 kW连续波速调管、80 kV/18 A基于脉冲步进调制技术的PSM电源、环流器以及相应的波导传输系统等。根据ADS总体指标和RFQ的相关技术参数,提出了功率源的总体布局、技术指标以及设计要求等,在此基础上完成系统安装与调试,并通过专家组测试与验收。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.
