Abstract
A passive non-electric pressure control system for a superconducting magnet cryogen vessel to maintain internal pressure above the outside pressure to avoid cryopumping utilizes a passive thermal conductor extending from the outside atmosphere into the vessel. The selective amount of penetration of the thermal conductor into the cryogen vessel controls the amount of heat transferred to the interior of the vessel and thus controls the internal pressure of the vessel.
