High-Current Photoemission Glow Discharge in a Xe–Cs Mixture
An unusual glow discharge has been discovered in a Xe+Cs mixture. Its burning voltage is several times lower and the current density is 1–2 orders higher than the normal voltage and current of a regular glow discharge in pure xenon and cesium, respectively. These discharges occur in cesium lighting lamps of a pulse-periodic discharge when they are heated by the alternating voltage before applying high-current operating pulses at a xenon pressure of 20 Torr and a wide range of cesium pressures (10–6–1) Torr. The most probable origin of their occurrence is photoemission from W–Th–Cs structures on the electrodes under the impact of intense UV radiation of the cathode layer.
期刊介绍：
Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
