A cryogenic test stand for large superconducting solenoid magnets

A new test stand for testing large superconducting solenoid magnets at the Fermilab Central Helium Liquefier (CHL) has been designed, installed, and operated. This test stand is being used to test a coupling coil for the Muon Ionization Cooling Experiment (MICE), and future uses include solenoids for the Fermilab μ2e experiment. This paper describes the test stand design and operation including controlled cool-down and warm-up. Overviews of the process controls system and the quench management system are also included.
