SST-1 is a medium size superconducting (SC) tokomak operational at IPR in India. TF and PF sc coils are used to produce high magnetic field strength. Presently, 10 kA rated Vapour cooled current leads (VCCLs) for TF system is made of NbTi superconductor and copper heat exchanger. Similarly, 9 PF coils will be energised by individual power supplies requiring total 18 VCCLs under pulse...
Current lead’s Joule-heating and conduction losses are main parts of superconducting cable’s cryogenic system total heat load. Superconducting energy pipeline is a new type of hybrid superconducting energy transmission cable, and the heat leakage of its current lead is not negligible.
In this paper, the process of superconducting energy pipeline current leads design, optimization and...
For the Beijing Spectrometer III (BESIII) superconducting magnet alternate upgrade project, two 4kA HTS current leads were designed, manufactured and tested. The baseline design of the current leads adopted a stacked YBCO conductor solution to achieve a lower thermal load at 4K, improve the stability of the magnet, and meet the requirements in the upgrade project that the unchanging of...
The design, analysis and experimental test of a High Temperature Superconductor (HTS) current leads with parallel HTS tapes is presented. Two HTS tapes are electrically shunted in parallel in each positive and negative lead respectively to increase its current-carrying capability. It is essential to enable balanced current sharing between the parallel HTS tapes to prevent potential overload...
