quench

An MRI term for a loss of superconductivity, an event that can only occur in superconducting magnets and results in total magnet failure. It is characterised by a rapid rise in magnet resistivity, which generates enough heat to evaporate the magnet coolant (liquid helium), creating a hazard that requires emergency venting to protect patients and operators.

quench,

v to cool a hot object rapidly by plunging it into water or oil.
