摘要
The cross bar H mode (CH) cavity is suitable to accelerate the low energy and medium energy proton. Theoperating mode in the CH cavity is H210. Compared with other low-beta superconducting cavities, the CH cavitywith multi-cell structure has high real acceleration gradient. In superconducting CH cavity, the cross bar is helpfulto rigidize the cavity mechanically. Since the year of 2011, IMP have involved into the research of superconductingCH cavity for the ADS project[1]. There are three CH cavity have been fabricated, one copper model CH cavityand two niobium superconducting CH cavity[2].
