Development of 12 kA-Level Forced-Flow Cooling HTS SMES System for NICA Accelerator / J.Zheng, H.Khodzhibagiyan, M.Novikov // International Conference on Applied Superconductivity and Electromagnetic Devices (ASEMD 2023), Tianjin, China, 27-29 Oct. 2023 [Electronic resource]. – [S.l.] : IEEE, 2023. – P. 10369100. – URL: https://doi.org/10.1109/ASEMD59061.2023.10369100. – Bibliogr.: 4.

Accelerator Complex such as NICA built in JINR has superconducting magnets operating at 10 kA level, the stable operation of which needs high performance SMES system to achieve energy compensation. The SMES needs to be operated with several kA-level current carrying and kA/s current ramping rate. The AC loss heat deposition resulting from fast current ramping makes immersion cooling and conduction cooling method inapplicable. The world’s first forced flow cooling 0.5 MJ HTS SMES with 6 kA current capacity based on CORC cable is being developed at ASIPP. For achieving better bending performance and control the ohmic loss in the mandrel of the CORC cable, we choose flexible metal conduit as the mandrel and casing externally. The combined action of internal and outer cooling channels can realize satisfactory cooling effect. For reducing the AC loss heat deposition during fast current changing, the CORC cable is wound with variable winding angles at different layers. A special designed HTS joint is designed for realizing the kA-level current transferring and forced cooling. Now the engineering design of the HTS-SMES is finished, which consists of 8 sub-solenoid coils and the inductance is 28 mH. The coils are cooled by forced flow supercritical helium and operated at 6 K. The manufacture is undergoing and will be finished in 2023.
