Measurements of front velocity and transported electron beam current are reported for several configurations of dielectric guide. It appears that the ions which determine the speed of beam-front propagation come only from a short section of dielectric near the inlet of the guide. They are accelerated in the potential well of the virtual cathode formed when the space-charge-limited electron beam is injected. Plasma formed by electron bombardment of the downstream guide walls apparently does not influence the beam-front speed, although it is important in determining the efficiency of current transport. Measurements of collective ion acceleration have been deferred until the second year of the program.
