BEAM-PLASMA DISCHARGE GENERATING DEVICE Russian patent published in 2016 - IPC H01J37/77 

FIELD: physics.

SUBSTANCE: invention can be used when designing novel high-current electronic devices, which enable obtaining sheet-like beams of accelerated electrons and high-power nanosecond current pulses, in plasma engineering, electron-beam technology, experimental physics, in gas discharge physics, in gas laser engineering and physics, when designing switches, pulsed nanosecond current sources, pulsed optical radiation sources with high brightness, large emitting surface and high efficiency, plasma-chemical engineering and experimental physics. The beam-plasma discharge generating device includes a discharge chamber and an electrode system consisting of extended electrodes. The discharge chamber is in the form of a quartz tube in which there is an electrode system consisting of aluminium electrodes; the anode is in the form of a flat plate and the cathode is in the form of a cylindrical rod, along which a rectangular cavity is cut, and a half of the discharge region is bounded in the transverse direction by dielectric walls. The lateral walls are half made of aluminium inside the cathode band and half made of fibre-glass plastic in the region between the cathode and the anode.

EFFECT: obtaining an extended homogeneous volume discharge and significant sharpening of voltage and current pulses and increasing the discharge current value by more than an order while limiting the discharge region.
