For the new test facility EDIPO (European DIPOle), to be hosted by CRPP, two 18kA HTS current leads were manufactured and successfully tested. The HTS module, made of AgMgAu/Bi-2223 tapes, is cooled only by heat conduction to the cold end, while the copper part is cooled by forced flow helium gas. The current leads were tested at low voltage up to the maximum current of 18kA. The helium mass flow rates required for stable operation at various currents were determined. In addition to the steady state operation, the transient behavior in the case of a loss of flow was studied experimentally. The test results provide an estimate of the operational limits of the EDIPO HTS current leads.

    • ...A set of 17 kA HTS current leads, based on Bi-2223 soldered stacks was assembled and tested in April 2010 using the 18 kA power supply delivered and commissioned in late 2009 together with the high voltage switches and dump resistor for quench protection, see Fig. 15. The detailed layout of the leads and the results of the test are reported in [9]...
