Summary

THE AUTHORS DESCRIBE A LARGE TEST FACILITY FOR 1.8 K OPERATION OF SUPERCONDUCTING MAGNET MODELS WHICH HAS BEEN BUILT AT CEN/SACLAY. THIS FACILITY IS INTENDED FOR TESTING ACCELERATOR MAGNETS DEVELOPED AT CERN FOR THE LARGE HADRON COLLIDER PROGRAM. IT IS DESIGNED IN SUCH A WAY THAT MAGNET MODELS CAN BE OPERATED EITHER IN AN EXISTING THERMALLY-INSULATED VACUUM TANK OR DIRECTLY IN THEIR OWN CRYOSTAT, WHICH ENABLES MAGNETS OF ANY LENGTH OR STRINGS OF MAGNETS TO BE TESTED. THIS FACILITY CONSISTS OF A 4.4 K, 200 WATT REFRIGERATOR (TO BE REPLACED SHORTLY BY A 450 WATT UNIT) AND A SATELLITE MODULE INCLUDING THE 1.8 K, 30 WATT REFRIGERATOR STAGE AND TWO 20 KILOAMPERE CURRENT LEADS INTERFACED WITH THE MAGNETCRYOSTAT. A FIRST SHORT LENGTH DIPOLE WAS TESTED IN JANUARY 1989, REACHING A FIELD OF 9.3 T.
