A glow discharge lamp with supplementary excitation by a radio-frequency discharge-preliminary measurements

Walters P.E. ; Human H.G.C. (1981)


The emission radiant output of an ordinary glow discharge plasma was increased by several factors through secondary inductively coupled RF excitation produced by an external coil and a 136.2MHz oscillator. The gain factor was determined at several glow discharge currents and voltages in copper alloys and cast iron samples. Improved linear calibration curves were obtained because the RF-boosted glow discharge source decreased the effect of self-absorption. © 1981.
