Magnetoresistance of cryogenic linear temperature sensor

The 40 T hybrid magnet was developed at High Magnetic Field Laboratory, Chinese Academic of Science, it is composed of 30 T resistive magnet insert and 10 T superconducting outsert which is cooled with forced flow of supercritical helium at 4.5 K supplied by cold box and valve box. The gaseous helium temperatures in valve box are measured by CLTS (Cryogenic linear temperature sensor). This paper presents the characteristics of CLTS, reports the magnetoresistance of the CLTS which is 5.8 m away from 40 T hybrid magnet centre when the 10 T superconducting outsert was in the field of excitation, and CLTS resistance offset for remanent magnetization. CLTS was not influenced by resistive magnet because of the small stray field of hybrid magnet 30 T resistive magnet.
