GAS DISCHARGE SWITCHBOARD Russian patent published in 2019 - IPC H01J17/02 

FIELD: electrical engineering.

SUBSTANCE: gas-discharge switch relates to electronic engineering, can be used to create pulse devices. Switchboard includes a housing made with the possibility of filling it with a working gas and sealing it, with the formation in it of a discharge region between high-voltage electrodes – a coaxial cathode and an anode. Cathode is made in the form of a shell covering the discharge area, the anode is in the form of a grid. Cathode and the anode in the form of a grid are installed with a gap relative to each other and represent a discharge structure providing a discharge gap. In the housing, a second discharge structure is located comprising a cathode of said first discharge structure and a dielectric capillary structure provided with an additional anode is located to form an additional discharge gap. Latter is made in the form of a dielectric body with a through hole of a discrete-variable diameter, which is a discharge channel, with periodic alternation of sections of the hole with diameter d₁ and hole portions with diameter d₂, where d₂<d₁. Due to the presence of areas with a diameter d₂ a capillary channel is formed with an axis coinciding with the axis of the first discharge structure. Additional anode is installed in one of the ends of the housing in the hole made for this purpose on the axis of the cathode in the form of a shell and the anode in the form of a grid with a discrete-variable diameter adjoining the outlet of the through hole.

EFFECT: increase in the degree of compression of the primary pulse and an increase in the pulse repetition frequency to tens of kHz with an increase in the degree of compression of the pulse and the preservation of the subnanosecond duration of the leading edge of the switched pulse.
