超导CH结构是一种新型的多室腔，用于中低能区质子和离子的加速。CH结构是一个交叉杆型腔，它是第一个工作在H模式的超导低能多室腔。成功地建立了一个具有19个间隙的超导CH-原型腔，其间隙为$\ensuremath{\beta}=0.1$。最大表面场为25 MV/m，相应的有效腔电压增益为3.7 MV。本文介绍了这种新型谐振腔的研制和试验情况。这也包括调谐和耦合方法，以及与其他低能量腔的比较。
The superconducting CH structure is a novel multicell cavity for the acceleration of protons and ions in the low and intermediate energy regime. The CH structure is a cross-bar-type cavity; it is the first superconducting low energy multicell cavity operated in an H mode. A superconducting CH-prototype cavity with 19 gaps at $\ensuremath{\beta}=0.1$ has been built and tested successfully. Maximum surface fields of $25\text{ }\text{ }\mathrm{MV}/\mathrm{m}$ and a corresponding effective cavity voltage gain of 3.7 MV have been achieved. In this paper the development and the tests of this new cavity are presented. This includes also tuning and coupling methods as well as a comparison with other low energy cavities.
