“…Thomson [4] suggested a simple model of the RF discharge giving a qualitative description of the extinction curves [2]. Rohde [5] measured the extinction curves of the RF discharge in air, oxygen, hydrogen, helium, neon and argon in the range of wavelengths 2.16-9.8 m for the gaps between flat electrodes of 19 and 38 mm, as well as the dependence of the discharge extinction voltage in air on frequency in the range of 0.1-150 MHz. Llewellyn Jones et al registered the extinction curves in air, hydrogen [6] and helium [7] in concentric cylinders at frequencies between 3.5 and 70 MHz.…”

“…The sheath becomes large at either very low or very high rf voltages, yielding a double-valued maintenance curve. Some measurements of maintenance can be found in the literature for argon [5][6][7][8] and some molecular gases [9] at moderate pressures (below 1 Torr) over a limited range of discharge plate separations. Measurements of electrical characteristics, but not maintenance, over a wide range of pressures and voltages have been reported for argon [10].…”

“…Le point M2 subit un déplacement analogue par rapport à la courbe U2e, d'où un nouveau maximum de Eo. Rohde, qui avait essayé de mesurer la conductibilité dans une décharge H. F. [5], avait déjà noté qu'on observe la plus grande conductibilité pour la fréquence appliquée à la pression correspondant au minimum du potentiel minimum d'entretien. Rotzeig, dans le court résumé publié sur ses recherches [6], a confirmé que le courant redressé à excitation constante en fonction de la pression donnait une courbe directement inverse de celle du potentiel minimum d'entretien en fonction de la même variable.…”
