Abstract

A quench simulation model is analyzed by means of control theory for optimal computational efficiency relative to a complex network of coupled shells. The authors describe the superconducting magnet configuration and the time domain aspects. They then discuss quench transient analysis and force transient analysis. The control theory analysis derived identifies an optimal computation efficiency for the numerically intense problem of 3D quench analysis with coupled circuits. This scheme of numerical time step integration has wider applicability.<>
