Electronic circuit for the detection and analysis of normal zones in a superconducting coil

摘要

A method of detecting and analyzing normal zones in a superconducting coil which involves generating a signal representative of the real power dissipated within the superconducting coil after the background noise and transient conditions within the coil have been accounted for. The power signal is integrated with respect to time to provide a signal proportional to the total energy dissipated within the superconductor which is then compared against a critical reference signal so that a quench signal is generated to immediately disconnect the superconducting coil when the reference signal is exceeded and to allow the coil to discharge its energy into an external device to prevent coil damage. An exemplary circuit for implementing the method is disclosed.
