Abstract
A superconducting magnet arrangement including: an outer vacuum container (OVC) housing magnet coils; a cryogen vessel thermally linked to the magnet coils; a cold head sock accommodating a cold head, with a thermal contact provided between the cold head and the magnet coils; tubes linking the interior of the cryogen vessel with the interior of the cold head sock; and a thermosiphon circuit defined by the cryogen vessel, the tubes, and the cold head sock. Pre-cooling and removal of ice build-up may be performed using the thermosiphon circuit.
Claims8
A superconducting magnet arrangement comprising:
- an outer vacuum container (OVC) housing;
- magnet coils;
- a cryogen vessel thermally linked to the magnet coils;
- a cold head sock accommodating a cold head, and a thermal contact provided between the cold head and the magnet coils;
- tubes linking an interior of the cryogen vessel with an interior of the cold head sock such that a thermosiphon circuit is defined by the cryogen vessel, the tubes, and the cold head sock;
- and
- an auxiliary vent tube providing a fluid path from the cryogen vessel to an exterior of the OVC housing.
