A cryostat has a tank for accommodation of a coolant and at least one superconducting magnet coil to generate a magnetic field. The tank has on a top side at least one tower pipe for filling the coolant and/or for venting vaporized coolant. In order to immediately indicate if and when sealing of filling pipes and discharging pipes with (for example) ice has occurred, a pressure sensor is connected via a pressure sensor pipe with the inside of the tank.
