| 摘 要： | 从双间隙分离腔的色散关系式出发，通过数值计算求出了分离腔中IM010模对应的谐振频率，并给出了腔内轴向电场的分布图，证实了分离腔中存在着电场反相的π模场。因此，可以将其用作电场反相的双间隙输出腔，来实现双间障提取。并用2.5维粒子模拟程序——卡拉特（KARAT）程序对这种分离腔输出回路进行了粒子模拟和优化设计。通过详细的冷测和调试实验，研制出了中心频率为3.74GHz、QL值为7.8的低QL值双间隙输出腔。

| Abstract: | New type,soft switching capacitor charging techniques are introduced. The basic circuit which employs a series resonant topolgy has the advantages of zero current switching,constant current charging and inherent short circuit protection. Formulae of calculating important parameters of this basic circuit are derived. A circuit with 16kJ/s charging ability is modeled and simulated.A real charging power supply of 2kJ/s is measured and waferorms are given. Under the adverse condition of high repetition rate and small load capacitance, methods of improving the regulation of charging voltage based on basic circuit are proposed while keeping the advantages of constant current charging. |
