Abstract

To fulfill the normal operational requirements of the fourth generation electron cyclotron resonance ion source (FECR) superconducting magnet, a cryostat in the form of liquid helium immersion was designed based on several Giffod McMahon cryocoolers. Considering the substantial number of current leads (a total of 9) and the high current value (with the maximum current of 709 A) of the superconducting magnet, a dedicated current lead test platform was designed and constructed to ensure operational stability and thermal management of the cryostat. This platform was utilized to conduct comprehensive tests on the high temperature superconductivity (HTS) leads and room temperature copper leads intended for use in the cryostat, including quantitative evaluation of conductive heating load and Joule heating load under operational conditions. The test results demonstrate that the designed leads can meet the normal working requirements of the FECR cryostat, achieving a maximum current capacity of 720 A with heat load of 28.88 W per copper lead and 0.12 W per HTS lead, respectively.

FECR低温恒温器的电流引线测试

为了满足第四代电子回旋共振离子源（FECR）超导磁体的正常运行要求，在多台gifford McMahon制冷机的基础上，设计了液氦浸没低温制冷机。考虑到超导磁体的电流引线数量较多（共9根），且电流值较大（最大电流达709 a），为保证低温恒温器的运行稳定性和热管理，设计并搭建了专用的电流引线测试平台。利用该平台对低温恒温器使用的高温超导（HTS）引线和室温铜引线进行了综合测试，包括在运行条件下的导电热负荷和焦耳热负荷的定量评估。实验结果表明，设计的引脚能够满足FECR低温恒温器的正常工作要求，每根铜引脚和每根高温超导引脚的热负荷分别为28.88 W和0.12 W，最大电流容量为720 a。
