1. 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 the cryogen vessel with the cold head sock such that a thermosiphon circuit is defined by the cryogen vessel, the tubes, and the cold head sock;
a connecting port coupled to the cold head sock and providing a fluid path from the cryogen vessel to an exterior of the OVC housing;
an auxiliary vent tube providing a fluid path from the cryogen vessel to an external cooling arrangement; and
a thermal intercept thermally linking a location on the auxiliary vent tube to a location on the cold head sock.
