BLAST-EMISSION SOURCE Russian patent published in 1995 - IPC

FIELD: heavy-current electronics. SUBSTANCE: blast-emission source includes pulse voltage generator, electron gun, cathode, anode, vacuum chamber, vacuum channel, separating magnet. Anode has carbon cloth and belt with elements of ions. Firstly vapors material of belt which is wound into spiral uniaxially with carbon cloth are formed across initiator of anode plasma with amplification factor of electric field. Then voltage pulse forming blast anode plasma from which ion beam is withdrawn goes with some time delay to anode. Vapors of material of belt are formed due to its sputtering with electron from nanosecond electron gun. Controlled inductance is placed between pulse voltage generator and electron gun to control duration of front of accelerating voltage of electron gun. EFFECT: generation of homogeneous ion beams and expansion of range of element composition of ion beam. 1 dwg
