Abstract
A new class of coil and associated components network topology produces increased efficiencies of conductor utilization with improved quench protection in a passive mode. The electrical circuit characteristics result in a uniform and rapid global exhaustion of the stored energy. The electrical network design includes eigenvalue spectrum frequencies that are much higher than the dominant, which corresponds to the natural rate of energy decay by resistive dissipation. The high frequencies are associated with large fractional shifts of system currents and energies. The fast transients allowed by the high frequency channels produce substantial losses and quick reduction of critical margin.
