METHOD FOR INITIATION OF HIGH-VOLTAGE DISCHARGES IN ATMOSPHERE Russian patent published in 2014 - IPC H01T19/00 

FIELD: electricity.

SUBSTANCE: invention refers to methods for formation of discharges in the atmosphere. The invention suggests method for initiation of high-voltage discharges in the atmosphere, according to which electric discharge channel is formed between objects having different electrical potentials, and field intensity between them is close to threshold intensity value when electric breakdown occurs; the channel is formed in the area of suggested presence O₂ ^- negative ions and their accumulation till steady-state concentration is reached, and the above concentration of the above ions is kept within period of time required for development of discharge, at that creation and accumulation of O₂ ^- ions is made by impact on the atmosphere within the area of suggested location of the above channel by pulsed laser radiation ensuring ionisation of oxygen molecules with radiation by pulse train with pulse repetition period in the train less than time of O₂ ^- negative ions life in the atmospheric air and pulse duration in the train from 1 ps up to 10 ps, and delivery of the pulse train is supplied within time of O₂ ^- ions life in the atmospheric air.

EFFECT: increasing time for maintenance of discharge state.
