    A crossed field tube is used as an on-off switch to produce square, 25 ¿s wide current pulses at 40 kV and 3.2 kA. Operation is also demonstrated at 120 Hz at an initial 50 kV and 1.3 kA for a ten pulse train. Calculations indicate that continuous operation at over 150 kW of average power is possible with a suitably designed cooling system. A crossed field tube operated in this way has a higher c...

    Cathode spot theory provides two limiting approaches for the description of reality: The SMOOTH SURFACE MODEL and the ROUGH SURFACE MODE. For the SMOOTH SURFACE MODEL limits of the typical parameters, like current density and spot temperature can be calculated. For the SPOT AT REST we find only the (0)-MODE with typical current density values of 0(105A/cm2) on copper. For the MOVING SPOT we have b... View full abstract»

  • Electrical Charging of Shuttle Orbiter

    Publication Year: 1976, Page(s):229 - 240
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2345 KB)

    The Space Shuttle Orbiter has the geometrical configuration of an aircraft and nonconducting outer skin that is expected to generate considerable transient charging and local potential differences due to the ambient ionospheric plasma. Emission of high-current electron beams has been proposed for the AMPS Spacelab payload that would induce large potentials and return currents to the orbiter skin. ... View full abstract»

    The numerical solutions of Boltzmann transpott equation for the energy distribution of electrons moving in crossed fields in nitrogen have been obtained for 100 ¿ E/p ¿ 1000 V M-1 Torr-1 and for 0¿ B/p ¿ 0.02 Tesla Torr-1 using the concept of energy dependent effective field intensity. From the derived distribution functions the electron mean energy, the tranaverse and perpendicular drift velo... View full abstract»

  • The Electrostatic Trapping of an Intense Relativistic Electron Beam in a Magnetic Mirror

    Observations of rapid axial oscillations of an intense relativistic electron beam in a magnetic mirror are reported. The mirror field primarily provides radial confinement of the relativistic electrons. The axial confinement was achieved by placing thin aluminized mylar foils at the conjugate mirror field maxima. The region between these foils was filled with a few Torr air to provide a beam induc... View full abstract»

  • Computational Study of MHD Equilibrium of Noncircular Tokamak Reactor Plasmas

    Publication Year: 1976, Page(s):249 - 254
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (956 KB)

    The MHD equilibrium and stability of noncircular tokamak plasmas limited by a separatrix is studied for reactor size systems. A typical example with a plasma current of 15.8 MA and major radius of 8.1 is presented. The required vertical field is generated by a set of discrete external coils and no conducting shell is included. The detailed equilibrium shape is calculated numerically for a vertical...

  • Field Penetration into a Plasma with Current Saturating Conductivity

    The problem of electric field penetration into a plasma is investigated employing a nonlinear current saturating conductivity. The case of step electric field applied at the boundary of semi-infinite plasma is studied. It is observed that the skin penetration depth is much larger than the one predicted by the linear theory and is comparable with the rapid field penetration reported in some turbule...

    In this paper we describe the research on supplementary heating of toroidal plasma made in France at the Commissariat a l'Energie Atomique and in the European Community (with special reference to the J.E.T. project) in the frame of the national programs. A non exhaustive description of the world effort on this topic is also presented. View full abstract»

  • Parametric Decay of Electron Electrostatic Waves Pumped by an Electromagnetic Wave

    Publication Year: 1976, Page(s):272 - 280
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1394 KB)

    In a computer simulation study, we have observed the parametric decay of an electromagnetic wave propagating parallel to the DC magnetic field into two electron electrostatic waves. We have identified the mechanism as three-wave parametric interaction. The growth constants of the decay waves have been measured. After saturation, the decay waves are observed to trap electrons. Consequently, the vel... View full abstract»

    A modified Korteweg-de Vries equation in a two-dimensional space comprising the externla magnetic field and the direction normal to a density gradient is derived for a plasma consisting of warm ion fluid (¿i = 3) and nonisothermal electrons (¿e > 1). The effect of ionic temperature and resonant electrons (both trapped and free electrons) on the amplitude and the width of the drift solitary wave ... View full abstract»

    Nonlinear ion-acoustic waves, which in the absence of collisions are moderately stable in the long wave length limit, become modulationally unstable due to presence of collisions. These waves are unstable in the wave number range kmin < k < kmax. View full abstract»

  • Lower Hybrid Heating of an Electron-Cyclotron-Resonance Plasma in a Canted Magnetic Mirror

    Plasma heating at the lower hybrid resonance was studied experimentally in a canted magnetic mirror in order to determine the effects of magnetic field curvature on heating efficiency. Heating occurred mainly on what would be the "outside" of an equivalent torus, peaking near the hybrid resonant layer. The best conditions for heating were seen to be a relatively flat density profile of magnitude s... View full abstract»
