论文摘要
对于下一代线性加速器进行研究，工业和医学应用的线性加速器，加速结构的需求很大。在紧凑型XLS项目的框架中，纵向空间阶段的线性化需要超高梯度更高的谐波RF加速结构。为了确定正常导电的RF动力颗粒束加速器中最大的可持续梯度，RF崩溃的可能性极低，在使用KA波段制度中使用短裤加速结构正在进行研究。我们在这里报告了紧凑型线性化站立波（SW）加速结构的电磁设计8厘米长，在$π$模式下运行，相对于Linac频率（11.994 GHz），第三个谐波，具有100 mV/m的加速梯度和最小的表面电场。通过使用众所周知的超级鱼类，HFSS和CST计算软件进行了数值电磁研究。
There is a strong demand for accelerating structures able to achieve higher gradients and more compact dimensions for the next generation of linear accelerators for research, industrial and medical applications. In the framework of the Compact Light XLS project, an ultra high gradient higher harmonic RF accelerating structure is needed for the linearization of the longitudinal space phase. In order to determine the maximum sustainable gradients in normal conducting RF powered particle beam accelerators with extremely low probability of RF breakdown, investigations are in progress for using shorts accelerating structures in the Ka-band regime. We here report an electromagnetic design of a compact linearizer standing wave (SW) accelerating structure 8 cm long operating on $π$ mode, third harmonic with respect to the Linac frequency (11.994 GHz) with a 100 MV/m accelerating gradient and minimum surface electric field. Numerical electromagnetic studies have been performed by using the well known SuperFish, HFSS and CST computing software.
