This paper mainly presents the multi-physics studies of this cavity, include electromagnetic design, mechanical analysis and multipacting simulation, to predict its behaviour under practical operating process. Various transverse vibration modes of inner conductor were found under different fixed conditions and an asymmetric shorting plate was adopted to avoid high possibility of multipacting PB - JACoW Publishing CP - Geneva, Switzerland SP - 863 EP - 865 KW - cavity KW - multipactoring KW - simulation KW - SRF KW - accelerating-gradient DA - 2019/01 PY - 2019 SN - 2226-0366 SN - 978-3-95450-194-6 DO - DOI: 10.18429/JACoW-LINAC2018-THPO076 UR - http://jacow.org/linac2018/papers/thpo076.pdf ER -
