APPARATUS FOR GENERATING VOLUMETRIC SELF-SUSTAINED DISCHARGE Russian patent published in 2014 - IPC H01S3/38 

FIELD: physics.

SUBSTANCE: apparatus for generating volumetric self-sustained discharge has a discharge chamber in which are mounted three electrode pairs which are connected to a pumping source, each pair consisting of plate-like profiled electrodes. Each cathode plate is situated in the plane of the corresponding anode plate and electrode pairs are mounted either parallel to the longitudinal axis of the chamber or at an acute angle to said axis. The working edge of the central cathode plates has at the centre a straight portion to which portions with a Stepperch profile adjoin at both sides. The working edge of the central anode plates has an arched shape and faces the discharge gap with its convex surface. Portions of the working edges of the outermost anode and cathode plates, facing the centre electrodes, repeat the profile of the working edge of corresponding anode and cathode central plates. Outer portions of working edges of the outermost anode and cathode plates have an arched shape and a longer length than portions of working edges of the outermost anode and cathode plates facing the centre electrodes, wherein all portions of the working edges have smooth mating.

EFFECT: enabling generation of a uniform volumetric self-sustained discharge between pairs of electrode plates in different gaseous media.
