建立了低杂波系统调试平台,在此平台上对4只TH2103A型高功率速调管及传输线主要部件进行了短脉冲调试,对每只速调管运行参数进行了优化和标定。在50k V/20A的束电流条件下,速调管工作脉冲脉宽为30ms,4只速调管输出功率分别为449k W、417k W、460k W和450k W。测试数据和调试结果为下一步在HL-2A装置上建设低杂波系统、开展物理实验等提供了重要的参考数据。 A low-noise system commissioning platform was set up. On this platform, short-pulse tests were carried out on the four main components of TH2103A high-power klystron and transmission line. The operation parameters of each klystron were optimized and calibrated. At a beam current of 50k V / 20A, the pulse width of the klystron operates at 30ms and the output power of the four klystrons is 449kW, 417kW, 460kW and 450kW, respectively. The test data and debugging results provide the important reference data for the next step in building a low-clutter system on HL-2A devices and carrying out physical experiments.
