Electromagnetic Field Measurements Near a Single-Stage Reconnection Gun.

Abstract

Electromagnetic (EM) field measurements were obtained near a single-stage reconnection gun accelerating a 194-gm, 4 x 4.5 x 1/4 in. aluminum plate. This type of EM launcher is of interest as an alternative for using explosive charges to launch a plate in the edge-on orientation. Electric and magnetic field measurements were designed to characterize the transient EM environment (EME) external to this capacitor-based EM launch system. The available data are included and selected data are discussed to illustrate the time history and spatial variation of the measured EME. The early time EM fields associated with this system are directly related to the coil current, but under operational conditions there is a late-time electric field associated with the induced eddy currents in the plate. This report summarizes progress to date in characterizing this EME in terms of the relevant system parameters such as coil current and plate velocity.
