Abstract:
1. A system for creating a magnetic field including: a first branch comprising a superconducting magnet configured to produce said magnetic field, said magnet being formed by a coil inductance (L′) in series with a residual resistance (R′ a second branch comprising a protection resistance (R′ a third branch comprising a power supply; a fourth branch formed by a resistance (R′ said system presenting at least three modes of operation: a first mode of operation, corresponding to a charge mode or discharge mode of the magnet, in which: a second mode of operation, corresponding to a normal mode of operation, in which: a third mode of operation, corresponding to the rapid discharge mode of the magnet in said protection resistance (R′ wherein activation of the state of said limiter in said three operation modes is done in a passive manner without resorting to an external command.
