Patent ID: 8441764

Claim:
A quench propagation arrangement for a superconducting magnet comprising: first and second series-connected superconducting coils each being connected on a first side to a common node, the first superconducting coil being connected on a second side to a first node; a first diode having a cathode connected to a positive supply line and an anode connected to the common node; a second diode having a cathode connected to the positive supply line and an anode connected to the first node; a third diode having an anode connected to a negative supply line and a cathode connected to the common node; a fourth diode having an anode connected to the negative supply line and a cathode connected to the first node; a number of heaters, respectively thermally connected to each of the superconducting coils and electrically connected between the positive supply line and the negative supply line; and a voltage limiter connected between the positive supply line and the negative supply line, in parallel with the heaters.
