论文摘要
在紧凑型光XLS项目的框架中，请求在Linac频率的第三个谐波上进行短的超高梯度线性化器。增加梯度和降低维度是XLS和所有下一代线性加速器的要求。实际上，在KA波段政权中运行的超紧凑型正常导电加速结构范围为100至150 mV/m，以实现用于研究，工业和医疗应用的超高梯度。为了满足这些强大的要求，必须使用RF功率输出和高效率的适当KA波段Klystron的R $ \＆$ d。该贡献报告了可能在36 GHz的Klystron放大器管设计的设计，以馈送相位空间线性化器，同时在输入处接收，低级信号在12 GHz处振荡；这是Linac频率。提议的结构达到42 $ \％$和20兆瓦的RF功率输出的效率。这项贡献还讨论了高功率直流枪，光束聚焦通道和RF光束动力学。
In the framework of the Compact Light XLS project, a short ultra-high gradient linearizer working on the third harmonic of the main LINAC frequency is requested. Increasing gradients and reducing dimensions are requirements for XLS and all next generation linear accelerators. Actually, ultra-compact normal conducting accelerating structures, operating in the Ka-band regime ranging from 100 to 150 MV/m are required to achieve ultra-high gradients for research, industrial and medical applications. To fulfill these strong requirements, the R$\&$D of a proper Ka-band klystron with RF power output and a high efficiency is mandatory. This contribution reports the design of a possible klystron amplifier tube that provides and output signal at 36 GHz to feed the phase space linearizer, while receiving at the input, a low level signal oscillating at 12 GHz; which is the LINAC frequency. The proposed structure reaches an efficiency of 42$\%$ and a 20 MW RF power output. This contribution discusses also the high-power DC gun, the beam focusing channel and the RF beam dynamics.
