Abstract:

Moving striations in a direct current glow discharge were studied in neon over a pressure range of 10.1 mm to 50 microns of mercury and a current range of 7 to 0.01 milliamperes. Tubes of constant diameter, one of 2.54 cm, another of 0.55 cm, were used. Regions, normally at pressures less than 8 mm and currents less than 1 ma, were found in which no striations were evident either in photomultiplier traces on an oscilloscope or in rotating mirror observations. An investigation was conducted to determine the limits of the striation free regions in each tube and striation stability in adjoining areas. In the regions of instability a wave was noted which appeared to be traveling in the opposite direction and at a much greater velocity than the positive moving striations. This wave, though evident in rotating mirror observations, was undetectable with the photomultiplier tube.
