Magnetic bearings and noncontacting seals let cooler operate unattended at 65 K for more than 3 years. New cooler uses magnetic bearings, small piston/cylinder clearance seals, and linear motors. Cooler consists of compression and expansion sections connected end-to-end. Compression section houses reciprocating hollow piston driven by linear motor.
