Experimental and Theoretical Evaluation of Electromagnetic Environment Produced by Direct Electron Injection at AURORA

Abstract

A mosaic of experimental data accumulated during the last year or two indicates that when operated in the electron injection mode AURORA can produce a very fast electromagnetic response in a large number of sensors. These fast responses are consistent with an electromagnetic environment in the AURORA test cell that has a very fast rise time. The electromagnetic parameters that have been measured and found to have rise times less than 10ns are the electric field and the magnetic field. The rise time of the relativistic electron current has also been found to be approximately 10ns at a number of positions in the AURORA test cell, but not at all positions. Two possible mechanisms that contribute to the fast rise time are: 1) electric field clipping due to conductivity, and 2) beam erosion due to the inductance of the electron beam in the AURORA test cell.
