Results of the test of the European LCT coil in the TOSKA facility

The forced flow cooled European LCT coil was tested successfully as a single coil in the Karlsruhe test facility TOSKA. Operation at design conditions (10 kA, 5.6 T at 4.8 K and 6 bar) was achieved without any problems. Cryogenic, mechanical and electrical performance was in agreement with predictions. Due to the high stability, the coil could be operated close to its critical parameters by heating the supercritical helium up to about 6 K. The coil stayed superconducting even after a fast dump (7 s) from full current. Good performance is also expected for operation in the 6 coil toroidal array of the LCTF.
