Abstract From the Canadian patent

A gas-discharge chamber electrode is proposed comprising, a hollow metal member with an emitting portion on the gas-discharge side and with coolant pipes. The hollow metal member is coated on the outside, except for the emitting portion with, a high-temperature dielectric. The electric system includes at least two such electrodes. The invention is intended for use, primarily, in designing electric-discharge reactors for plasmochemistry, in laser engineering for electric-discharge lasers with transverse gas flow, as well as in electrophysical engineering.
