【摘要】：在高能同步辐射光源验证装置(HEPS-TF)的插入件系统中,将要研制一台基于镨铁硼永磁铁的低温波荡器(CPMU)。低温波荡器要求磁铁磁极阵列工作温度要在85 K以下,同时整个大梁轴向的温度梯度不超过1.5 K/m。经过理论计算,低温波荡器在有束流情况下的热负荷约660 W@80 K。为冷却低温波荡器大梁磁结构,设计了一套过冷液氮闭循环迫流冷却系统。为了确保磁铁有更好的低温效果和温度均匀性,低温波荡器内大梁采用了双通道冷却设计。最后,根据低温流程设计了可行的机械结构,称其为液氮过冷器冷箱。
[Abstract]:In the insert system of HEPS-TFM, a low-temperature waver based on praseodymium iron-boron permanent magnet is to be developed. At the same time, the axial temperature gradient of the whole beam is not more than 1.5 K / m. The theoretical calculation shows that the thermal load of the low temperature waver is about 660 W @ 80K. it is a magnetic structure for cooling the beam of the low temperature waver. A set of supercooled liquid nitrogen closed circulation forced flow cooling system is designed. In order to ensure the magnet has better low temperature effect and temperature uniformity, double channel cooling design is used in the beam of low temperature waver. According to the low temperature process, a feasible mechanical structure is designed, which is called the liquid nitrogen supercooler cooler.
