HEAVY-CURRENT ELECTRON GUN Russian patent published in 2004 - IPC

FIELD: generation of heavy-current electron beams for electronic heavy-current pulse amplifiers and for material surface treatment.

SUBSTANCE: proposed electron gun designed to produce electron beam whose pulse energy is raised by 30 - 40% and beam length and stability of its parameters are enhanced from pulse to pulse has explosion-emitting cathode 1, plasma anode 4 depending for its operation on reflective discharge, and collector 3; gun is placed in external guiding magnetic field 7. Grounded diaphragm 2 whose opening diameter is smaller than that of cathode is placed between explosion-emitting cathode 1 and reflective discharge anode 4. In addition reflective discharge anode 4 accommodates spark-gap plasma generators 5 whose cathodes are connected to ground through limiting resistors 6, and reflective discharge anode 4 proper is common anode for plasma generators.

EFFECT: reduced radial current leaks, time difference in reflective discharge transfer to heavy-current stage, and absolute value of this time.
