The applicability of various linear electron accelerators for the acceleration of heavy pulsed currents is estimated. It is shown that linear standing-wave electron accelerators, which use the high-frequency power stored in resonant cavities, for the acceleration of particles offer greater possibilities in comparison with ordinary linear traveling-wave electron accelerators. The possibility of accelerating currents of the order of 100 amp in pulses with a duration of approximately 1 μ sec is demonstrated.

An electron linear accelerator capable of providing high pulsed currents of accelerated electrons is described. The accelerator consists of two coupled resonators excited at a frequency of 137.4 Mc/s by 12 auto-generators each delivering up to 100 kW of power in a 400 μsec pulse. Results obtained with this accelerator are in accordance with the theoretical calculations(1). An electron current of 8.5 A was obtained in a pulse of 0.2 μsec duration and at an energy of 4.5 MeV. The maximum charge of the accelerated electrons per pulse was 3 × 10-6 C.
