Description

Jinhua Light Source, which is a industrial light source, will be built in Jinghua City, Zhejiang Province, China. Its energy is 2.6 GeV and beam current is 500 mA. 4 sets of normal-conducting RF systems are likely to be chosen. A kind of 500 MHz HOM-damped normal conducting RF cavity has been designed for the Jinhua Light Source. The KEK-PF main cavity type was selected and three rectangular waveguides equally spaced by 120°. One of the rectangular waveguides is longitudinally separated from the other two rectangular waveguides. The main mode is TM010 mode and the effective shunt impedance is greater than 7.5 MΩ. The simulation results show that longitudinal HOM impedance is no more than 1 kΩ and transverse HOM impedance is no more than 50 kΩ/m.
