Professional software is presented for superconducting quench simulation, applicable to magnets with a single or multiple coils, with or without iron, operating in either the persistent mode or from external power. Drift, dump and charge simulations are also possible. The method assumes that a quenc

โฆ Synopsis
Methods to increase quench currents of superconducting magnets and to make them more predictable are discussed. Some of the methods are well known while others are unusual (like that of 'electrodynamic treatment').
The results of practical implementation of all methods under discussion are presented.

A small superconducting magnet coil, 16.39 cm outer diameter and 7.62 cm inner diameter, has been quenched to determine the rate of decayof current in the coil and to measure the temperatures in the coil induced by the quench. The measured current decay and the temperatures have been compared with t
In large superconducting magnets built using force-flow cooled conductors, such as those being designed for next generation fusion machines, the quench propagation is a threedimensional phenomenon. In this paper we develop a method for the analysis of quenches in 3-D which is extremely versatile and
The minimum energy required to quench a fully impregnated superconducting winding has been measured at a constant field of 5 T for various currents. Great care has been taken to match the experimental conditions with those presumed in the minimum propagating zone (MPZ) treatments of the situation. I
Theory based on the minimum propagating zone (MPZ) criterion overestimates the critical heat of quench in partially stabilized superconducting magnets. The discrepancy is especially important for high values of the Stekly parameter. In this paper the variational principle for the calculation of crit
