Shkarofsky and published by . This book was released on 1970 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report discusses the experimental observation of enhanced transmission of a strong right-hand circular wave near cyclotron resonance in an afterglow helium slab plasma occurring at earlier times than for a corresponding weak electromagnetic field. A strong field heats the electrons and alters the collision frequency and the velocity distribution function. For our experimental conditions, electron-electron relaxation processes can influence the distribution function. Furthermore, because of the field dependent absorption coefficient, the temperature and field strength can vary within the plasma slab. Although the collision frequency increase with temperature predicts an earlier time for stronger-field transmission at cyclotron resonance, none of the above processes is sufficient to explain the experimentally observed large spread in times of transmission for various electric field strengths. The explanation is ascribed to the fact that the electron density decay constant due to diffusion also increases with temperature, so that the electron density decay rates vary with electric field resulting in a larger spread in times of transmission. Experimental results from double probes and interferometer phase measurements also indicate a decrease in density subject to strong fields. (Author).

This book was released on 1966 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Linearly polarized incident electromagnetic waves were propagated along the direction of a static magnetic field through a helium afterglow plasma in the frequency region of the electron cyclotron frequency. The experimental measurements illustrate clearly the behavior of the two transverse wave modes that the plasma can support. At high electron densities the right-hand circularly polarized component is completely attenuated and the variation of the transmitted signal is due entirely to the left-hand circularly polarized component. Alternately at low electron densities the plasma is transparent to the left-hand mode and the variation in transmitted signal is due to the righthand mode. Detailed comparisons of measurements of the phase and intensity of the components of the electric field transmitted through the plasma in the same orientation as the incident polarization and cross-polarized to the incident polarization show good agreement with theory.
