TEST FACILITY FOR SIS300 CRYOMODULES

Within the framework of cooperation with GSI (Darmstadt, Germany), IHEP develops the superconducting quadrupole and corrector magnets, which in the specific combinations will be united into the so called cryomodules having common cryostat. The facility for testing these cryomodules in the forced flow cooling mode, where it is intended to carry out the complex of electrical, magnetic and thermophysical tests, is examined. The facility is based on the existing helium compression and purification equipment, helium refrigerator and research cryostats. A satellite refrigerator is added to the cryogenic system, which also works as the helium mass flow rate multiplier.
