COAXIAL DIODE WITH MAGNETIC ISOLATION OF PULSE HEAVY-CURRENT ACCELERATOR OF RELATIVISTIC ELECTRON BEAM OF MICROSECOND DURATION Russian patent published in 1995 - IPC

FIELD: accelerating equipment. SUBSTANCE: coaxial diode has blast-emission cathode anchored on cathode holder, vacuum chamber which is simultaneously anode and solenoid. Cathode is manufactured in the form of ring of wedge-shaped section with radial sharp edge directed outside which outer radius creates fixed magnetic field tube. Distance form this tube to any point of cathode holder from which emission is possible is bigger than length of divergence transverse to magnetic field of plasma formed at cathode holder for the course of pulse duration. EFFECT: enhanced operational efficiency. 4 dwg
