在快速循环同步加速器（RCS）中，由于金属真空室上的涡流而导致的功率损耗会导致真空室加热。研究其对估算涡流感应功率损耗和温度增长的影响具有重要意义。本文分别导出了偶极真空室和四极真空室涡流损耗的解析公式。利用CSNS/RCS偶极子模型进行了实验验证。将推导的公式应用于RCS真空室某些特殊结构的涡流功率损耗计算。
In a Rapid Cycling Synchrotron (RCS), power loss due to an eddy current on the metal vacuum chamber would cause heating of the vacuum chamber. It is important to study the effect for estimating eddy current induced power loss and temperature growth. Analytical formulas for eddy current power loss for various types of vacuum chambers are derived for dipole and quadrupole repectively. By using the prototype of dipole of CSNS/RCS, an experiment was done to test the analytical formula. The derived formulas were applied to calculating the eddy current power loss on some special structures of an RCS vacuum chamber.
