This paper describes the cryogenic tests of the TPC 2-meter-diameter superconducting solenoid on a 200 W refrigerator with gas-bearing turbines. The solenoid is cooled with two phase helium in forced flow around the superconducting winding. The two-phase helium was circulated using either the J-T circuit flow or a bellows type liquid helium pump. The particular problems associated with running a variable load on a gas-bearing turbine refrigerator are discussed.
