摘要

Summary form only given, as follows. Glow-to-arc transitions infilamentary glow discharges in atmospheric air can be largely avoided byuse of a plasma cathode, as has been demonstrated in short filamentarydischarges in air. In these experiments a dc-driven microhollow cathodedischarge (MHCD) was used as a plasma cathode to sustain a stable,direct current discharge between the plasma cathode and a thirdpositively biased electrode. We have, using the same concept, extendedthe gap distance (distance between plasma cathode and third electrode)from previously 2 mm to the range from 6 mm to 20 mm and have studiedthe electrical, optical and plasma properties of such long filamentaryglow discharges in atmospheric air. The MHCD is ignited between closelyspaced molybdenum electrodes, separated by a 130 μm thick aluminalayer, with a 130 μm hole through the sample. The filamentarydischarge was ignited at small gap distances, in order to keep theignition voltage at a low level, and then the gap was extended to thedesired distance. In a certain range of current the filamentary glowdischarge (FGD) current was found to be identical to the microhollowcathode discharge current. In this range control of the FGD by the MHCDis possible. From previous measurements of short gap filamentarydischarge the gas temperature was found to be approximately 2000 K], theelectron density was estimated as close to 1013 cm-3. We will report on the results of measurements of these plasmaparameters in long filamentary air discharges, and the electricalparameters, which determine the current range of MHCD control of theFGD. Parallel operation of these controlled filamentary glow dischargesby using individual or distributed ballast might allow the generation oflarge volume, high pressure glows in air
