TUPSA047	Preliminary Study on Graphene Coated RF Cavity
	Q.S. Chen, L. Cao, K. Fan, T. Hu, B. Qin, P. Tan, Y.Q. Xiong HUST, Wuhan, People's Republic of China
	Graphene has attracted great interest ever since due to its excellent performance in chemical and physical properties. For the aspect of modern accelerator technology, high beam power and stability are two main concerns. In this paper we will give a preliminary study on graphene coated RF cavities and show some potential advantages related to the graphene coat. Especially for the high electrical conductivity of graphene, it is possible to achieve a CW operation which is comparable to a superconducting machine. Another important character is the low multipacting, which would greatly reduce RF breakdown and improve the stability of the whole system.

Magnetic structure was changed from three-phase structure to four-phase structure. Accordingly, excitation voltage was changed from three-phase sinusoidal wave to square wave. Polyimide was chosen as insulation material instead of teflon or mica. A prototype of 400kV/50mA was designed, simulated and verified with the aid of finite element analysis software. To optimize the voltage distribution, corresponding flux compensation methods were raised to solve the problem of flux leakages.

Insulated core transformer (ICT) high voltage power supply is an ideal model for industrial radiation accelerator at energy below 1MeV. Compared to the traditional scheme, a novel ICT high voltage power supply was put forward. Conventional silicon steel sheets were replaced with manganese zinc ferrites, raising working frequency from 50Hz to thousand hertz. Magnetic structure was changed from three-phase structure to four-phase structure. Accordingly, excitation voltage was changed from three-phase sinusoidal wave to square wave. Polyimide was chosen as insulation material instead of teflon or mica. A prototype of 400kV/50mA was designed, simulated and verified with the aid of finite element analysis software.
