Optical detection of surface discharges
IEEE Transactions on Electrical Insulation, 1988The use of an optical detection system for measuring surface discharges is described. A photomultiplier tube (PM) transforms the photon pulses emitted by the discharge process into an electrical signal. To suppress the noise inherent to PM operation, filters were built in the amplitude- and time-domains. Results of discharge measurements showed that in

Microwave Discharges and Their Application. I. Surface Microwave Discharge
Moscow University Physics Bulletin, 2019This article presents the results of a series of fundamental studies on a new type of a surface microwave discharge conducted at the Department of Physics of Moscow State University. The discharge is created by a surface wave on a dielectric antenna when powerful electromagnetic radiation in the centimeter wavelength range is supplied to it.

Controlled discharge on dielectric surface
12th International Conference on High-Power Particle Beams. BEAMS'98. Proceedings (Cat. No.98EX103), 2002The paper proposes technique for controlled commutation of energy on a dielectric surface when affected by ultraviolet radiation, formed during electric explosion of wires. Commutation characteristic of discharge can be controlled by changing intensity of surface irradiation and number of commutation channels by changing number of exploded wires.

3.0-ns surface discharge development
Journal of Applied Physics, 1986The nanosecond time-scale developing mechanisms of positive and negative corona streamers on the insulation surface are investigated using a square pulse generator and the Lichtenberg figure technique. The developing length of the corona streamers in air is measured at a pulse duration of 3 ns, an applied voltage of 7–20 kV, and a gas pressure of 150 ...

Origin of surface microwave discharges
Technical Physics, 2011The high-pressure gas discharge initiated at the focus of pulsed powerful microwave radiation is a branched network of thin plasma channels completely filling the volume of the focal zone. A detailed experimental investigation of such discharges is carried out with a setup operating at a wavelength of 8.9 cm and at pressures ranging from 0.05 to 1.00 ...

Physics of Surface-Wave Discharges
1997The existence of electromagnetic waves guided by a plasma-dielectric structure was disclosed by Trivelpiece and Gould in 1959 [1]. Initially designated as space charge waves, then as Trivelpiece-Gould modes, they are now more widely known as (electromagnetic) surface waves (SW). In the sixties, many articles were devoted to the study of such waves (see
