Abstract : A steady state thermal analysis of the superconducting magnet (SCM) in the Advanced Lightweight Influence Sweep System (ALISS) was performed using commercial Finite Element Modeling (FEM) software. Cryocooler interface temperature from a no-load performance curve and uniform heat flux due to radiation, conduction and instrumentation heat leaks were input as the boundary conditions. Two major cases were examined: one with instrumentation heat flux dispersed around the SCM and one with instrumentation heat flux concentrated. Both resulted in the SCM staying within temperature specifications. A separate group of exploratory cases determined the heat flux values that "quenched" the SCM, causing cessation of superconductivity. (MM)
