DESIGN OF TEST CRYOSTAT FOR SUPERCONDUCTING SOLENOID MAGNETS

Abstract The cylindrical cryostat for testing superconducting magnets is designed. It consists of two vessels, the inner one for cooling the superconducting magnets with liquid helium and the outer one for providing the heat sink of 77K thermal shield with liquid nitrogen. The thermal shields are placed between the liquid helium vessel and the external housing, which are wrapped with multilayered superinsulation. The size of the cryostat is about 800 mm in diameter and 2200 mm in height, with the liquid helium consumption rate of 0.7 liter per hour without current leads. In this article, the design features, structural and thermal analysis of the cryostat are discussed
