Description
40 T hybrid magnet combining a set of resistive magnet with a superconducting outsert, was carried out at High Magnetic Field Laboratory, Chinese Academic of Science (CHMFL). The superconducting magnet is forced flow cooled with supercritical helium at a temperature of 4.5 K and pressure above 5 bar. The cryogenic Distribution Box distribute refrigeration power to the outsert superconducting magnets, and the helium temperature of the cryogenic Distribution Box is measured by cryogenic linear temperature sensor(CLTS).One CLTS nearest from 40T hybrid magnet appeared obvious magnetoresistance when superconducting outsert magnetic field is above 7T, and the magnetoresistance are plus or minus alternately with magnetic field,the largest temperature error is 1K.The magnetoresistance disappeared when superconducting magnetic field is below 7T.
