FIELD: electricity.
SUBSTANCE: discharge is ignited between a flat cathode and an anode, which is made in the form of a thin needle with a small radius of rounding. The proposed invention makes it possible to produce a stable microdischarge with a quite simple and inexpensive method, which does not require vacuum plants and does not require external injection of electrons, since the discharge burns in atmosphere and is independent. The invention may be used to create plasma-chemical reactors and gas analysers, and also in plasma sputtering and alloying of materials in sections of micron size.
EFFECT: increased stabilisation of a smouldering microdischarge under atmospheric pressure.
