Abstract
The paper presents the results of experiments with fast electrons generated by laser radiation with energy of about 30 kJ, intensity of 3·1014 W·cm−2 and duration of 5 ns focused on a metal target. It is shown that in the evacuated interaction chamber a flux of electrons, having energies of about 10 keV and a neutralized spatial charge and diverging over distances of meters from the target, is formed. The amplitude of the generated current is about one hundred megadampers, which also indicates a complete current compensation of the electron flux. According to the estimates, the charge neutralization and the current compensation can be provided by weakly ionized plasma formed in the interaction chamber due to residual gas when pumping the chamber to a pressure of 10−3 Torr. The effect of generating such electron fluxes is of interest for radiation-related applications and academic problems related, for example, to the development of filament instability in plasma.
