Abstract: To develop a high current neutron generator, preliminary studies on a high current, high duty factor 4-rod RFQ accelerator has been carried out in the Institute of Heavy Ion Physics,Peking University. This paper discusses the design of a cooling system of the RFQ cavity. Finite element program ANSYS was used to analyze the cooling system. The power density was simulated by MAFIA and used as the boundary condition of ANSYS. Due to the different meshing methods between MAFIA and ANSYS, a program was written to transfer the result of MAFIA to ANSYS. Then a thermal analysis model of RFQ cavity was built by using ANSYS. The design of the cooling system was analyzed and checked by using this model, and then the structure of cooling system is determined. Simulation results showed that the design of the cooling system makes RFQ accelerator working at proper temperature and long time steadily.
