A new cryogenic test facility for superconducting magnets at IMP

Abstract To test the superconducting magnets for HIAF, CiADS and other scientific research projects, a new cryogenic test facility is under construction at IMP. The cooling power of the refrigerator in this test facility is 500 W @ 4.5 K and the liquefaction capacity is 150 L/h. Three vertical test cryostats and three horizontal test benches are planned. A 700 mm inner diameter vertical test bench and one general horizontal test bench is under installation. A standalone cool-down/warm-up unit which can supply 30 g/s helium gas at 80 K is designed. The commissioning of the cryogenic plant includes the refrigerator, the helium recovery system, the purifier, the gas tanks and the vacuum system have been finished, and the installation of two test benches are almost done. The general design and some features are described in this paper.
