摘要
采用理论计算与ANSYS仿真相结合的方法,针对一种工作频率为975MHz,平均电场强度为3.7MV/m,加速质子能量范围从80MeV至300MeV的边耦合腔直线加速器的加速腔,进行了散热结构的设计。通过理论计算确定了冷却结构的基本尺寸,然后采用ANSYS进行了热-结构-高频多场耦合仿真。得到了该冷却结构下的频移为-0.427MHz,频移对温度的敏感度为9.93kHz/℃,均处于可控范围内。该设计方法和流程可用于其他类型的谐振腔冷却结构的设计。
To develop the coupled-cavity linac(CCL),which works at 975 MHz,3.7MV/m of averaged electric field,and accelerating proton from 80 MeV to 300 MeV,the cooling structure was designed and the thermal analysis was carried out.Theoretical calculation was used to determine the dimension of the cooling structure and ANSYS was adopted to do the thermal analysis including thermal-structure-radio frequency coupling problem.The results show that the frequency shift is-0.427 MHz,and the sensitivity to temperature is 9.93kHz/℃.It is within control range.In addition,the design and analysis method can be used to the cooling structure design of other types of resonant cavities.
