The Direct Injection of Electron Pulses into Air -- An SREMP Simulation Tool
Abstract
Proper simulation of a source-region EMP environment requires the presence of time-varying air conductivity and space current. In the experiments described here, these features are produced by the AURORA Flash X-Ray Machine operating in the electron mode, rather than the less efficient bremsstrahlung mode. The primary goal of this experiment was to achieve a high dose over a large volume with a fast rise time. A great concern to the experimenters was overcoming the hose instability with its problems of unpredictability and nonuniformity. This was done by passing the electron beam (8.5 MeV, 200 kA, 200 ns), produced from a 53 em diameter toroidal cathode, through a 0.15 em steel window into the exposure room. This procedure scattered the beam enough to inhibit beam instability.
