Abstract

In a method and system for shutting down a superconducting magnet of a magnetic resonance apparatus using a monitoring processor and an energy store, the monitoring processor determines stored energy stored in the energy store at a first point-in-time, and determines a ramp energy required for shutting down, and determines a second point-in-time based on the stored energy and the ramp energy. At the second point-in-time, shutting down of the superconducting magnet is begun.
