“…A passive protection system is adopted to protect the superconducting magnet from damage caused by quenching. Cold diodes are laid across the subdivision to reduce both the voltage and temperature of the hot spots [9]. The magnet is assumed to be in an open loop state with an operating current of 180 A.…”

“…The back-to-back cold diode configuration eliminates the risk of unidirectional connection of the magnet power supply. Various types of cold diodes have been extensively used for subdivisions of multi-coil superconducting magnets for high-energy particle accelerators or MRI scanners [4][5][6][7][8][9][10][11][12]. The back-to-back cold diode assemblies (DA-1 and DA-2, as shown in figure 1) across each subdivision ensure the bypassing of the operating current through the cold diodes if the voltage across each subdivision (SD-1 or SD-2) of the magnet exceeds the resultant forward voltage or the threshold voltage (hereinafter 'turn-on' voltage) of each diode assembly during a quench of the MRI magnet.…”
