ABSTRACT:
A superconducting coil system comprising a superconducting coil and a normal conducting coil, the normal conducting coil having a current time constant (L2/R2) which is larger than L1/R1, or the time constant at which the current through the superconducting coil decays rapidly after the conductors in the superconducting coil made a transition to the normal conducting state, in which L1and L2represent the self-inductances of the superconducting coil and the normal conducting coil, respectively, R1represents the resistance for causing rapid decay of the current flow through the superconducting coil, and R2represents the resistance of the normal conducting coil.
