CALCULATION OF UNSTEADY TEMPERATURE PROCESS AT COLD END OF CURRENT LEADS FOR BEPCⅡ

Zhang Xiaobin Wang Li Wang Tianhao Jia Linxiang(Institute of Cryogenics and Superconductivity Technology, Harbin Industry University, Harbin 150001)  
A method of theory calculation for the unsteady temperature process at the cold end of the current leads for BEPCⅡ is introuduced.The results accord well with the results of numerical simulation by Fluent6.0. This method is used to analyze the effects of cooling helium mass flow of steady operation on the velocity of the temperature rise at the cold end of the current leads.
