ABSTRACT:
Device for dissipation of gases created in the event of a quench of a superconducting magnet has a quench tube and a front sealing element closing the quench tube on the magnet side. The quench tube is sealed by a rear sealing element, and at least one sensor is associated with the tube segment closed by the sealing elements. The measurement values of the sensor represent a measure for the impermeability of the tube segment. The sensor communicates with an alarm emitter via which an alarm signal can be output upon detection of a leakage of the tube segment.
