The most important recent scientific results:
A new class of steady-state solutions has been found in the theory of DC glow discharges and cathodes of high-pressure arc discharges. These solutions exist simultaneously with the solution given in textbooks, which describes a discharge mode with a uniform or smooth distribution of current over the cathode surface, and describe modes with different configurations of cathode spots: normal spots on glow cathodes, patterns of multiple spots recently observed on cathodes of glow microdischarges, spots on high-pressure arc cathodes. In particular, these solutions show that cathode spots represent self-organization phenomena and that basic mechanisms of near-cathode space-charge sheath can produce self-organization; another illustration of the richness of the gas discharge science. As far as arc cathodes are concerned, these multiple solutions have proved relevant for industrial applications.
