Concept for Spatial Visualization of Magnetic Fields from Exploding Wires
Abstract
The US Army Combat Capabilities Development Command Army Research Laboratory is interested in how EM fields couple with materials during dynamic events. In this work, we propose a novel method to spatially visualize magnetic fields in situ during dynamic exploding wire experiments for direct comparison with magnetohydrodynamic simulations and to identify where the current is flowing in complex pulsed power experiments. The technique involves characterizing exploding wire experiments simultaneously with X-radiography to inform about the wires structural location and proton radiography that is sensitive to contributions from both the structural and magnetic field contributions. The data will allow for an inference of where the magnetic fields permeate under the dynamic event and where the preferred conduction paths are located. This proposal was accepted by Los Alamos National Laboratory's (LANLs) proton radiography advisory committee, and experiments will be conducted during the summer of 2020 at LANLs proton radiography facility.
