Fabrication and test of a forced cooled Nb3Sn superconducting coil

The forced cooled Nb
3
Sn superconducting magnet has been manufactured and tested in a high field test facility(HFTF). It consists of 4 double pancake coils by wind & react process. The magnet has been successfully tested under 4T of the back up field of HFTF this August. The test results appear that the quench of the magnet has occurred under the conditions of 8,000A, 6T and 10.3K. Those results have proved the good performances of the conductor and its magnet.
