Sopke腔是一种新型的超导加速结构,也称为轮辐型腔(Spoke type cavity),主要用于中β加速段,国际加速器界正在努力推进其相关技术,而相当多的加速器设计方案采用了Spoke加速结构(图1)。相比于相同频率的椭球加速腔,Spoke腔的径向尺寸小;微波耦合能力强;不需要在束流管道上安装耦合腔,可以使其单位长度的 Sopke cavity is a new type of superconducting acceleration structure, also known as the Spoke type cavity (Spoke type cavity), mainly for the mid-beta acceleration section, the international accelerator community is working to promote its related technologies, and a considerable number of accelerator design used Spoke acceleration structure (Figure 1). Compared to the same frequency of the ellipsoidal acceleration chamber, Spoke cavity radial size is small; microwave coupling ability; do not need to install the coupling cavity in the beam pipe, you can make the unit length
