Approach to multicriterion optimization of quench performance of superconducting winding

In this paper, a multicriterion estimation of superconducting winding quench performance is presented, using the computational model. Method of searching for representative solutions based on the weighted min-max metric is outlined and then applied to a quadricriterion analysis of some transient characteristics of superconductivity loss in cryomagnet windings. It enables one to evaluate some optimal values of working current so as to minimize resistive zone voltage, a time interval at which the whole winding spare will be embraced by a resistive zone and maximal winding temperature.
