IONIZATION WAVES IN A LONGITUDINAL MAGNETIC FIELD.
Abstract
The effects of a longitudinal magnetic field (0 to 850 gauss) on running striations occurring in low pressure (0.1 to 2.0 mm Hg) glow discharges of Helium, Neon and Argon were studied. Also the electron temperature and the charge density profiles of particular striations were determined by Langmuir probe techniques. The variation of the striation parameters of wavelength, velocity and frequency were found to be oscillatory with the magnetic field intensity. The theory which was used to describe striations in a longitudinal magnetic field was found to be inadequate for the experiments. This was probably because the theory neglects end conditions which seemed to dominate in the short discharges studied. Other oscillations were also detected and found to be a result and a function of the magnetic field. The probe measurements showed the light intensity wave of the striation to be in phase with the charge density wave with the electron temperature wave leading by less than 90 degrees. (Author)
