“…As far as it is known [1][2][3][4][5][6][7][8][9][10][11][12], the breakdown curves of the glow discharge are described by Paschen's law U dc = f (pL), i.e. the breakdown voltage U dc depends on the product of the gas pressure p and the discharge gap L. De La Rue and Muller [13] were the first to observe the dependence of the breakdown voltage U dc on the product pL.…”

Abstract. This paper studies in experiment and theory the breakdown of argon, nitrogen, air and oxygen in a uniform dc electric field at different discharge gaps L, discharge tube radii R and cathode materials. At arbitrary geometric dimensions of the cylindrical discharge vessel and cathode materials the ratio of the breakdown electric field value to the gas pressure p at the minimum of the breakdown curves is shown to remain constant, (E dc /p) min ≈ constant. A modified breakdown law for the low-pressure dc dischargeThat is, the breakdown voltage U dc is shown to depend not only on the product pL, but also on the ratio L/R. A method is presented enabling one to predict a dc breakdown curve in the cylindrical discharge vessel possessing arbitrary L and R values from the measured data on the dc breakdown.

“…The collision frequencies used in the theory are a sum of y ei and y en (y in > Jei'Jen) ^^ lei obtained from Spitzer (1962) and y en from Brown (1959). To compute the neutral density in the discharge tube it is assumed that the pressure remains constant (at the controlled value) when the discharge is turned on while the number density of neutrals is reduced because of the increased gas temperature: the effect of thermal transpiration causes no drastic uncertainty of this reduction.…”

“…Brice & Smith (1964) have suggested that noise signals received by the Alouette I satellite are associated with this resonance. Fredricks (1968), using the kinetic dispersion relation, studied this resonance for perpendicular propagation in an infinite homogeneous plasma.. Stix (1965) has considered this resonance in an inhomogeneous plasma and has proposed a possible heating scheme using mode conversion.…”
