Abstract：
Intensive study has been done on low and medium energy section of proton and heavy ion accelerators. Many experiments show that spoke cavity is a very good candidate to connect low beta RFQ (radio frequency quadrapole) structure and high beta elliptical accelerating structure. A β=0.45, f=350MHz spoke cavity has been designed and a copper model spoke cavity has been fabricated at Peking University. In this paper, we put the emphasis on the analysis of HOMs (high order modes) of the spoke cavity.
