Abstract :
A compact subnanosecond accelerator producing an annular electron beam of duration up to 300-400 ps, energy ~250 keV, and current up to 1 kA has been developed to study experimentally the transient processes in high-pulsed-power, high-current microwave devices. The dynamics of the beam current pulse and the variation of the electron energy during the transportation of the beam in a longitudinal magnetic field have been investigated. The experimental data obtained are compared with the results of a numerical simulation
