Systems and methods for ramping down magnetic resonance magnet

A method for ramping down a magnetic resonance magnet contained in a storage container, the storage container containing an endothermic liquid, the method comprising:

• obtaining an environmental condition related to the magnetic resonance magnet;
• determining whether the environmental condition related to the magnetic resonance magnet satisfies a first condition;
• ramping down the magnetic resonance magnet in a first mode in response to a result of the determination that the environmental condition related to the magnetic resonance magnet satisfies the first condition, the first mode including:
• heating, by a first heater, a superconductor electrically coupled to the magnetic resonance magnet, wherein when the first heater increases a temperature of the superconductor by heating the superconductor, the superconductor is disconnected to the magnetic resonance magnet or the superconductor loses a superconduct condition;
• consuming electric energy from the magnetic resonance magnet, by an electric energy consumption device residing outside the storage container, when the superconductor is disconnected to the magnetic resonance magnet or the superconductor loses the superconduct condition, thereby ramping down the magnetic resonance magnet;
• determining whether the environmental condition related to the magnetic resonance magnet satisfies a second condition;
• and
• ramping down the magnetic resonance magnet in a second mode in response to a result of the determination that the environmental condition related to the magnetic resonance magnet satisfies the second condition. the second mode being different from the first mode.
