Current supply with high-temperature superconductors in a cryostat for superconducting magnets

摘要

A cryostat arrangement (1) for a superconductive magnet arrangement, with a helium tank (2) for liquid helium, wherein in the helium tank (2) the superconductive magnet arrangement (6) is arranged,with a nitrogen tank (3) for liquid nitrogen, wherein the nitrogen tank (3) surrounding the helium tank (2),and with at least one access tube (4), in which a current supply arrangement is mounted, by means of the current from the space temperature hot area of the cryostat (1) in the superconducting magnet arrangement (6) can be conducted,the current supply arrangement of at least one current line with a normally conducting conduit part (13) and a superconducting conduit part (14) composed of htsl - material is characterized in that a terminal (12) of the at least one current line, through which the normally conducting conduit part (13) with the superconducting conduit part (14) is electrically connected thermally to a wall of the nitrogen tanks (3) is coupled. In this way, a simple and cost effective cooling of the transition of htsl, to the normal conductor in the current supply is ensured.
