Title: Superconducting magnet system with inductive quench heaters
Inventor: LOWRY JERALD F
IPC: H01F6/02
Filed: 1991-12-02
Abstract: Abstract of the Disclosure A superconducting magnet  coil  is protected  from local damage due to quenching by inductively driven heaters formed by heater strips embedded in the coil and connected in closed loops.   A cold bypass diode shunting the coil winding  commutates  current  out  of  the  magnet  when  the voltage drop across the region of the coil which has gone normal exceeds the forward bias of the diode.  This change in coil current induces sufficient current in the heater loops to cause the entire coil to go normal for uniform dissipation of stored energy throughout the magnet.
