    An integral balance technique for calculation of the electron energy distribution in a radiation-induced plasma is described. Results predict W-values reasonably well and compare favourably with more complicated Monte-Carlo calculations. The distribution found differs from that in a normal electrical discharge and is of interest in radiation-pumped laser research. View full abstract»

  • Polarization Equation for a High-Frequency EM Wave Propagating through a Cold Plasma

    Publication Year: 1974, Page(s):211 - 214
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (773 KB)

    An equation is derived for the polarization of a high-frequency EM wave propagating through a cold plasma. The polarization is determined in a coordinate system fixed to the wave-normal. It is assumed that the plasma density varies slowly in only one direction and that the wave-normal and the external magnetic field B make arbitrary angles with that direction. View full abstract»

    An application is made of lumped feedback to achieve stability of a distributed electromechanical system. A conducting elastic wire, placed in an axial magnetic field and carrying a current, exhibits instability at a certain threshold of magnetic pressure. The two dimensional transverse displacement of the wire is sampled and these signals are used to produce proportional feedback forces which all... View full abstract»

    The technique for measuring electron temperature with an ion beam probe has been refined, the time resolution reduced and the limitations evaluated. The technique involves sequentially probing the same volume of plasma with beams of different ions species and using the observed secondary ion currents and the known ionizing cross sections to evaluate the electron temperature. Detailed measurements ... View full abstract»

    An experimental scheme is proposed which seems to satisfy all the requirements for use of a high energy electron beam to initiate a thermonuclear plasma. One-dimensional expansion is utilized to obtain confinement times longer than the pulse length of the electron beams. A magnetic field is used to limit the radial heat conductivity, and this magnetic field also serves as a guiding field for the e... View full abstract»

    Summarizes recent experimental data related to anode phenomena in both vacuum and atmospheric pressure arcs. Currents in the range 10 A to 30 kA are discussed, and particular emphasis is placed on the effect of plasma flow from the cathode. For vacuum arcs this plasma flow is the directed motion of metal ions from the cathode spots. These ions reduce the anode voltage drop, and maintain a diffuse ... View full abstract»
