Experimental Study of Propagation of Intense Relativistic Electron Beams in Nonconducting Vacuum Drift Tubes after Passage through a Localized Plasma Source

The propagation of intense relativistic electron beams into evacuated nonconducting drift tubes after passage through a localized plasma source has been experimentally studied. Time‐integrated photographs of the propagation process have been obtained, as well as quantitative measurements of the propagated beam current and energy.
