Cryogenic System and Magnetic Resonance Device

Abstract

The disclosure relates to a cryogenic system for a magnetic resonance device, comprising a magnet arrangement including at least one superconducting magnet, a first cryocooler thermally connected to the at least one superconducting magnet, a switching device, and a second cryocooler configured to cool a component of the magnet arrangement in dependence of the switching device, wherein the switching device is configured to enable cooling of the component of the magnet arrangement via the second cryocooler when a temperature of the component of the magnet arrangement exceeds a predefined temperature level, and to disable cooling of the component of the magnet arrangement via the second cryocooler when the temperature of the component of the magnet arrangement is below the predefined temperature level. The disclosure further relates to a magnetic resonance device, comprising a cryogenic system.
