MICROWAVE DETERMINATIONS OF AFTERGLOW TEMPERA TURES AND ELECTRON COLLISION PARAMETERS IN NITROGEN AND OXYGEN.
Abstract
The work on the microwave determination of after glow radiation temperatures, electron collision frequencies and fractional energy losses per collision in nitrogen and in oxygen is described. These determinations are based on measurements of the plasma conductivity and noise emission in a waveguide and on the variations of these quantities when additional microwave signals, capable of increasing the electron energies, are sent through the plasma. A transverse static magnetic field, perpendicular to the electric field in the waveguide, is also used in some experiments in order to increase plasma con ductivity and noise emissivity. The method, the computation formulas and the experimental techniques are discussed in detail. The ex periments performed and the results are compared with those of other authors; in most cases the agreement is quite satisfactory. (Author)
