为了研制一个强中子发生器,北京大学重离子物理研究所设计了一台高负载因子、高流强的RFQ加速器.本文讨论了RFQ加速腔水冷系统的设计,使用有限元软件ANSYS对水冷系统进行了分析.使用MAFIA模拟计算得到的功率密度,并将其作为ANSYS水冷模型的边界条件.因为MAFIA程序和ANSYS程序分网方法的不同,使用一个程序来将MAFIA的结果导入到ANSYS模型中,从而建立起了RFQ加速腔的热分析模型.通过这个热分析模型分析并检验了水冷系统的设计,确定了水冷系统的结构.模拟计算结果表明使用目前设计的这套水冷系统,能够使RFQ加速器工作在适宜的温度下以及长时间稳定的运行.
In order to develop a strong neutron generator, Peking University Institute of Heavy Ion Physics designed a high load factor, high flow RFQ accelerator.This paper discussed the design of RFQ accelerated cavity water cooling system, the use of finite element software ANSYS for water cooling system The power density calculated using MAFIA was used as the boundary condition for the ANSYS water cooling model.Due to the difference between the MAFIA program and the ANSYS program subnetting method, a program was used to import the MAFIA results into the ANSYS model to establish The thermal analysis model of the RFQ accelerating chamber was used to analyze and test the design of the water cooling system and to determine the structure of the water cooling system.The simulation results show that the current design of the water cooling system enables the RFQ accelerator to work at Suitable temperature and long-term stable operation.
