“…The high-frequency breakdown characteristics of various gases in the presence of a magnetic field were first studied by Townsend and Gill (1938) and have since been subjected to extensive investigations (Lax et al 1950, Ferriti and Veronesi 1955, Nagomyphi 1966, Bacri 1965, Nakamura and Mitani 1965, Sen and Ghosh 1963, Sen and Gupta 1969, Agnello et al 1966. However, almost all of these studies have been performed for the case of a perpendicular magnetic field where, owing to the presence of the magnetic field, not only the breakdown field is reduced, but resonance occurs when the frequency of the applied electric field is equal to the electron cyclotron frequency.…”

Radio-frequency (55 MHz) breakdown characteristics of air have been studied in the presence of a parallel low-intensity magnetic field over the pressure range of 5 to 115 mTorr. The breakdown potential has been found to decrease with increase in magnetic field intensity. This decrease is most marked at the lowest pressure. It has further been observed that, although the variation of breakdown potential with pressure shows a broad minimum in the presence of lower intensity magnetic fields, this variation becomes almost linear beyond 80 G. Thus an appreciable reduction in diffusion loss of electrons under the above mentioned conditions has been observed experimentally.

SummaryIn the experiences carried out on the capacitively excited high-frequency helium discharges a t pressures of 10-3-Torr, a spectral line intensities redistribution in helium spectrum in function of applied steady magnetic field magnitude has been observed. The magnetic field application modifies also the plasma dispersive properties, which are reflected in the variable relative weight of the h.f. field harmonics. The experiences evidenced an electron temperature dependence on the relative h.f. harmonics intensities, confirming the previous researche conclusion concerning the electron temperature increase with the electric field frequency.
