Abstract :
The paper is devoted to the study of how the irradiation of the electrode surface with a low-energy, high-current electron beam affects the prebreakdown current and the electric strength of the vacuum insulation. This study is an extension of the work by A.V. Batrakov et al. (see Proc. XVI Int. Symp. on Discharges and Elect. Insul. in Vacuum, p.360, 1994). Experiments have been performed for 0.1-mm vacuum gaps formed by refractory-metal electrodes and for millimeter vacuum gaps with a pulsed voltage of amplitude 250 kV and duration 30-100 ns
