100MeV负氢强流回旋加速器是北京串列加速器升级工程的重要组成部分,包含两套相似的高功率射频系统,采用双腔独立驱动的方法。每套高功率射频系统包括1台100kW射频功率源、1套约36m长的6英寸高功率传输线系统和1个射频谐振腔体。这两套系统的射频功率源和传输线系统于2009年末完成制造[1],2010年初全比例射频实验腔体完成加工[2],初步具备了进行高功率实验验证的条件。2010年夏天的初次高功率实验中,出现了以7次谐波为代表的高次振荡,对该射频系统的
The 100MeV negative hydrogen turbo accelerator is an important part of the Beijing tandem accelerator upgrade project. It contains two similar high-power RF systems and adopts a dual-chamber independent drive. Each high-power radio frequency system includes a 100kW RF power source, a 36m long 6-inch high-power transmission line system and a RF resonant cavity. The two system RF power sources and transmission line systems were manufactured by the end of 2009 [1]. In early 2010, a full-scale RF experimental cavity was completed [2], which initially provided the conditions for high-power experimental verification. In the first high-power experiment in the summer of 2010, a high-order oscillation represented by the seventh harmonic wave appeared,
