SUPERCONDUCTING MAGNET CRYOSTAT Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: superconducting magnet cryostat has case 1, magnet 3, and heat-insulating hangers 2. In case of cooling in respect to heat case, magnet 3 is locked in position by hangers attached to it below its horizontal axis and angle between horizontal axis and point of attachment is found from equation α = arc sinδL_t/RδR_m, where L is hanger length, δL_t is hanger relative strain, F_m is radius of magnet locking point, δR_m is magnet relative strength. In case of relative cooling of hangers and magnet, and their temperature strain, point of magnet attachment is displaced so that magnet axis does not change its position. EFFECT: improved precision of magnet locking in the course of cooling without changing its physical characteristics, facilitated manufacture of hangers and their simple design which makes it possible to simplify design of cryostat as a whole. 2 dwg
