Abstract

A double bath superfluid helium dewar has been constructed and operated at Fermilab’s Magnet Test Facility. The 1.8 K portion of the dewar is sized to contain a superconducting magnet up to 0.5 meters in diameter and 4 meters long in a vertical orientation in 0.12 MPa pressurized superfluid. The dewar can also provide a subcooled Helium I environment for tests; the entire temperature range from 4.4 K to 1.8 K at 0.12 MPa is available. This paper describes the system design, lambda plate, heat exchanger, and performance.
