【Abstract】 A 6T NbTi superconducting magnet cooled by a two-stage 4K G-M cryocooler was developed successfully in our Institute .The magnet was cooled to 4K about 74hr. At present the magnet system has been finished experimental examination for 115A(6T), 45hr and 95A, 264hr continuously.;The cryostat has 742mm outside diameter, 558mm height and 100mm room temperture bore. The magnet system can be rotated on a support frame with 0°, 45°, 90°.;The structural design of cryostat and test results of magnet system are mainly presented in this paper.更多还原
