Experiments on the Junction of Relativistic Electron Beams into Preformed Channels in the Atmosphere: A Feasibility Study
Abstract
A study was made of the interaction of an intense relativistic electron beam (REB) with a preformed reduced density channel in the atmosphere. The channel was designated by laser-induced, aerosol-initiated air-breakdown and was heated by passage of an electric current. However, at the time the REB was injected into the channel no externally applied heating current remained. By varying the time between creation of the hot channel and injection of the REB, we were able to observe interactions of the beam with both high conductivity and low conductivity channels. In the former case the beam did not propagate in the channel, whereas in the latter case the beam did propagate in the channel. These results are discussed in terms of the residual conductivity in the channel, and in terms of the radius of the return current distribution compared to that of the beam.
