| 摘 要： | 微波组近年来研制了一系列S波段干负载。使用CST对S波段系列干负载进行仿真优化设计,仿真结果在中心频率2856 MHz处电压驻波比均小于1.04,满足电压驻波比小于1.1的频带宽度都大于100MHz。以上所有干负载的实际加工产品低功率测试电压驻波比均小于1.05,其中14介质柱高功率干负载已由韩国完成了高功率测试,测试时在重复频率60Hz,脉冲宽度1μs,速调管输出50.7 MW的情况下,干负载电压驻波比为1.09且工作状态稳定。其他各型干负载也都已安装于国内外加速器上,经过了长时间的稳定运行,性能可靠。

| Abstract: | A series of S-band dummy loads are developed by microwave Group these years. After the simulation and optimization for the S-band series of dummy loads in CST, the simulation results show that all the dummy loads achieved a voltage standing wave ratio less than 1.04 as well as a frequency bandwidth more than 100 MHz (to satisfy voltage standing wave ratio less than 1.1). All the fabricated products of the mentioned dummy loads achieved a voltage standing wave ratio less than 1.05 in low power microwave test. Among which the 14-rod high power dummy load was tested for high power performance in South Korea, where VSWR of 1.093 was tested with a pulse repetition frequency of 60 Hz as well as a pulse width of 1 s and a klystron output power of 50.7 MW. The working state of the dummy load was stable. The other dummy loads mentioned were all assembled on accelerators domestic or abroad, all of which were very stable and reliable after a long time operation. |
