Paper Abstract

An engineering technique for determining the rail deflection of an Electromagnetic Gun during dynamic operation is described. The method uses a low-powered Helium Neon laser coupled with a fiber optic waveguide as a basis for the measurement system described. In addition to verifying the applicability of the photoeleastic effect in high electro-magnetic field environments, the tests yielded valuable information relating to rail behavior in an experimental barrel configuration. However, the approach described is applicable to most electromagnetic launch rail configurations.
