Investigation of drift dynamics and injection stability of high-current electron beam with picosecond resolution

The stability of the injection of short electron beams and the dynamic processes that occur during their transport were experimentally studied. Beams of energy 200-300 keV, current 1-1500 A, and duration 0.05-3 ns with a current rise time of 30-300 ps were formed in a cold-cathode electrode gaps. For measuring beam currents special collector probes were used which ensured a picosecond resolution.
