MAGNETIC SUSPENSION VEHICLE CRYOSTAT Russian patent published in 1994 - IPC

FIELD: refrigerating engineering. SUBSTANCE: cryostat has a vacuum shroud, a liquid cooling agent low-temperature vessel mounted inside. A superconducting magnet is positioned on the bottom of the vessel. Moreover, the cryostat has a screen with a tube heat exchanger located between the shroud and the vessel, a chamber positioned inside the vessel. The outlet branch pipe of the chamber is connected to the end of the heat exchanger, and the inlet branch pipe communicates with the vessel cavity in its upper zone. The chamber may be positioned in the upper part of the low-temperature vessel and may be made in the form of an inner frame of the superconducting magnet or made so as to position the magnet between its walls. EFFECT: improved structure. 6 cl, 3 dwg
