发明名称 METHOD FOR TESTING A SUPERCONDUCTOR UNDER INCREASED CURRENT LOAD IN A SERIES-PRODUCED AND ACTIVELY SHIELDED SUPERCONDUCTING NMR MAGNET
摘要 A method for testing a new superconducting wire involves charging an actively shielded magnet coil configuration which comprises a first partial region which can be superconductingly short-circuited using an additional switch. A superconductor to be tested under increased current load is used in this first partial region, thereby preventing superconductor in the second partial region from being subjected to this increased current load. Operating currents are determined for both partial regions that have the desired excess current in the first partial region, with the overall field B<SUB>0 </SUB>only slightly differing from the standard operating field of the magnet coil configuration. The operating currents are adjusted through initial charging of the overall magnet coil configuration, thereby taking into consideration the inductive coupling between the partial regions and after closing of the additional switch, by continued charging or discharging in the second partial region only. The method permits inexpensive testing of a superconductor in a series-produced NMR magnet under NMR conditions.
