【 摘 要 】

The Super-FRS magnets of the international Facility for Antiproton and Ion Research (FAIR) being built at GSI in Germany will be tested at a new cryogenic test facility currently under construction at CERN. During nominal operation the magnets will be cooled with liquid helium to 4.5 K. Over a period of three years in total 57 magnets will be tested of three different types. A study is performed to determine the cryogenic requirements for testing the Super-FRS magnets. The required operational parameters for the cool down, magnet test and warm up phases are determined and the results are discussed in this paper. For pre-cooling the magnets to 90 K with a rate of 1 Kh-1, a maximum cooling power of 5.6 kW is required. Cooling down the magnets further to 4.5 K and filling will be performed with LHe within 24 h. For warming up the magnets a maximum heater power of 14 kW is needed. It is concluded that the planned test facility currently under construction at CERN fulfills the cryogenic requirements for testing the Super-FRS magnets.
