Av. Batrakov et al., THE EFFECT OF PULSED ELECTRON-BEAM TREATMENT OF ELECTRODES ON VACUUM BREAKDOWN, IEEE transactions on dielectrics and electrical insulation, 2(2), 1995, pp. 237-242
A method for preliminary treatment of electrodes by a microsecond low-
energy intense electron beam is proposed. It has been demonstrated tha
t such a beam melts off the electrode surface and cleans the surface l
ayers from impurities and dissolved gases. In combination with subsequ
ent conditioning of the vacuum gap with low-current pulsed discharges,
high breakdown electric fields can be attained.
