CICC超导磁体低温冷却设计

The cryogenic cooling design of CICC superconducting magnet

介绍了CICC(Cable-in-Conduit-Conductor)超导磁体低温冷却设计过程,并结合合肥强磁场科学技术研究中心超导磁体工程技术部预设计的CICC尺寸,重点阐述了超导磁体运行工况的确定原则及超临界氦迫流冷却运行模式下的制冷工质压降计算,初步确定预设计参数是否具有可行性。

The process of cryogenic cooling design of CICC （ Cable - in - Conduit - Conductor） superconducting magnet is introduced. With the CICC parameter which is predesigned by the Superconducting Magnet Engineering and Technology Departraent of Hefei High Magnetic Field Laboratory, this paper mainly discussed the principle of how to ascertain the superconducting magneto running condition and the coolant＇s pressure drop under the circulating mode of forced flow cooling which uses supercritical helium as coolant, in order to decide the feasibility of the predisigned parameter in advance.
