Abstract
A magnet includes a stack of a plurality of superconducting pancake wound coils having a stacking axis normal to a winding direction of the coils. The stack has axial ends and has a stack midplane relative to the stacking axis. A quench detector is provided for detecting a quench in the stack of superconducting pancake wound coils. A plurality of resistance quench heaters (RQH) are distributed symmetrically along the axis with respect to the stack midplane. Control circuitry is provided for controlling the operation of the RQH upon the detection of a quench by the quench detector. A method of quenching a magnet is also disclosed.
