Abstract

Magnetic resonance apparatus (10'; 10"; 10"'; 10""; 50) with a superconducting, liquid helium-cooled magnetic coil system (13) arranged within a cryostat (11'; 11"; 11"'; 11""; 51) in a helium container (12'; 12"; 12"'; 12""; 52) wherein the helium container (12'; 12"; 12"'; 12""; 52) is surrounded by a chamber (14'; 14"; 14"'; 14"'"; 54) evacuated in the operating state of the magnetic resonance apparatus (10'; 10"; 10'"; 10""; 54) through which a helium path (15'; 15"; 15"'; 15""; 55) from the helium container (12'; 12"; 12"'; 12""; 52) to the outside of the cryostat (11'; 11"; 11'"; 11""; 51), wherein the cryostat (11'; 11"; 11'"; 11""; 51) has an overpressure cover (16'; 16"; 16"'; 16""; 56) on its outside, which opens when a predetermined internal pressure in the cryostat (11'; 11"; 11"'; 11""; 51) is exceeded and releases a gas outlet cross-section, characterized in that on the helium container (12'; 12"; 12"';12"") a cold rupture disc (17) is arranged, which is cooled to a temperature < 10 K in the operating state of the magnetic resonance apparatus (10'; 10"; 10"'; 10""), and which opens when a predefinable internal pressure in the helium container (12'; 12"; 12"'; 12"") is exceeded and releases a gas outlet cross-section from the helium container (12'; 12"; 12'"; 12"") into the chamber (14'; 14"; 14"'; 14"") surrounding the helium container (12'; 12"; 12"'; 12"").
