Abstract

The authors describe a method based on a magnetic vector potential development for calculating the joule heating of the conductors in arbitrary launcher geometries. The method accounts for the effects of varying conductivity of the launcher´s materials and can be implemented using available two-dimensional finite-element diffusion codes. Conductor temperature distributions as functions of time for a selected launcher geometry are provided to demonstrate the method
