METHOD OF GENERATING PLASMA OF GASEOUS MEDIUM AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2012 - IPC H01J37/04 H01S3/975 

FIELD: physics.

SUBSTANCE: high-voltage pulse is transmitted from a pumping oscillator, said pulse having amplitude higher than breakdown voltage U_br of the active gaseous medium and duration of not more than 100 ns with voltage rising edge of not more than 30 ns, an exciting inductor 6 with overall inductivity which satisfies the relationship 50 nH≤L/n≤500 nH, where L is inductance of one solenoid, n is the number of solenoids 5 connected in parallel and lying from each other at a distance h<H. The exciting inductor ensures efficient transmission of energy from the pumping oscillator to the gaseous medium in form of an alternating magnetic field. As a result of movement of changes, circular electric currents are induced, which form inductive vortex discharge in the gas within the width of the solenoids 5. In that case, the plasma of the inductive discharge takes the shape of a cylinder near the inner surface of the discharge tube, and then begins to interact with plasma of neighbouring solenoids, thereby increasing the total discharge length to n×H+(n-1)×h. If h>H, vortex discharge takes place only inside the solenoids of the exciting inductor and not in spaces between the solenoids.

EFFECT: high functional capabilities expressed in the increase in length and volume of exciting gaseous media with pulse transverse-longitudinal inductive discharge and improved operational characteristics of said radiation sources.
