Abstract
A 20T large bore superconducting magnet has been developed at the National Research Institute for Metals. In this paper, design for its cooling system is mainly discussed. As a coolant for this magnet, saturated superfluid helium has been applied. Two separated chambers where two coils are placed, respectively, are evacuated with rotary pumps. A liquid helium tank is equipped with each chamber over the coils. This tank functions as a reservoir of liquid helium and source of cooling gas for power leads. Two outer coils are designed to be cryogenically stabilized in saturated superfluid helium.Keywords
