【摘要】 针对传统S波段速调管尺寸大、重量重、成本高的问题,在传统速调管的重入式谐振腔中创新性地加载全金属互补电开口谐振环构建出一种具有小型化特性的超构材料速调管。CSTPIC模拟结果表明,当电子注电压为350kV、电子注电流为415 A、聚焦磁场为1800 G、输入信号的频率和功率分别为2.856 GHz和50 W时,该超构材料速调管的输出功率为61MW、对应的电子效率为42%、增益为60.86dB。该超构材料速调管高频结构的横向尺寸和纵向尺寸分别是传统速调管高频结构的82%和96%,此研究为应用于先进光源、未来环形电子对撞机等大科学装置中速调管功率源的小型化奠定了理论基础。更多还原

【Abstract】 In order to solve the problems of the large size, heavy weight, and high cost of traditional Sband klystron, a compact metamaterial-inspired klystron was novelly constructed by loading an all-metal complementary electric split ring resonator(CeSRR) into the resonator of the traditional klystron. The results,simulated and studied by CST PIC solver, show that the output power is 61 MW, the electronic efficiency is 42%, and the gain is 60.86 dB when the beam voltage is 350 kV, the beam current is 415 A, the focus magnetic field is 1800 G, the input signal frequency is 2.856 GHz, and the input power is 50 W. The transverse dimension and longitudinal dimension of the metamaterial-inspired klystron, which has obvious miniaturization characteristics, are 82% and 96% of the traditional klystron respectively. The study of this metamaterial-inspired klystron lays a theoretical basis for the development of the compact klystron used in the large scientific equipment such as the advanced light source, and the circular electron positron collider(CEPC).更多还原
