Abstract
Abstract 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 electrode system includes at least two such electrodes.
