Abstract:

A technique is developed to measure the surface temperature of an electrical conductor during a pulsed electrical discharge. The technique of two-color interferometry radiometry is used to make the temperature measurements. This report explains the technique and the issues encountered in performing such measurements. Also, a theoretical model for the current and heat transport for the pulsed conductor is developed. Predicted and experimental results are compared. The measurements can yield isothermal data that can be used to corroborate calculated current distributions in solid armature railgun operation.
