(19780101)The collisional, nonlinear trappedfluid equations of Kadomtsev and Pogutse (K.P.) are used as a description of the dissipative trappedion modes. The equations are solved numerically in two spatial dimensions as an ...

(19700601)Two methods are developed to solve an equation describing the equilibrium magnetic field associated with an Elayer in an Astron device. Because of problems related to bifurcation, all solutions are not obtainable by ...

(19750601)Measurements on the interaction between solid hydrogen pellets and rotating plasmas are reported. The investigations were carried out because of the possibility of refuelling fusion reactors by the injection of pellets. ...

(19811001)Evidence is presented that the currentconvective instability can be excited in experiments, in which an intense relativistic electron beam is injected into a cylindrical drift tube filled with a low pressure neutral gas ...

(19720401)Criteria for distinguishing between absolute and convective instabilities in an onedimensional, linear, infinite system have been derived by Briggs (1964), who showed that the use of the saddlepoint method fails in some ...

(19700501)A general criterion for electrostatic instability of either the convective or absolute type in a weakly inhomogeneous, hot magnetoplasma (slab model) is given in a form which makes convenient the determination of the density ...

(19800501)The energy reflected from plane metallic targets irradiated by 50 ps Ndlaser pulses, in the intensity range 10101012 W/cm2, has been measured. The authors find that for different conditions of incident energy and spot ...

(19811201)An analytical and numerical study of the absorption of a thermal plasma of finite density around the electron harmonics is presented. The absorption coefficient is evaluated by means of the energy conservation law and the ...

(19751201)The paper deals with the experimental study of the absorption of microwave energy in plasma in a strong magnetic field, omega ce/ omega >>1, where omega ce and omega are the electron cyclotron and wave frequency respectively. ...

(19820201)The authors consider the absorption of electromagnetic waves incident on the plasma surface in an electromagnetic trap. The electromagnetic waves are transformed in the plasma resonance region in the transition layer between ...

Absorption of infrared radiation as a general technique for the determination of plasma temperature(19700801)It is shown that the continuum absorption coefficient K( lambda ) of a plasma at temperature T and electron density N for radiation of wavelength lambda has the dependence K( lambda ) varies as z lambda 2N2T32/. The ...

(19680101)It is shown that the reflecting layer of a collisionless plasma behaves as a resistive system if there is a point where the plasma frequency is twice the frequency of the reflected light; the absorbtion of energy as well ...

(19771001)Consideration of the effect of plasma inhomogeneity on the beamplasma interaction is usually restricted to increasing density in the direction of beam propagation. Such an inhomogeneity is known to be stabilizing. Here, ...

(19670101)The acceleration of a plasma created in a toroidal stabilized pinch configuration has been studied experimentally. In an axisymmetric annular apparatus, a ring of plasma is produced by a pulsed azimuthal electric field in ...

(19691101)The velocity change of charged particles in a one dimensional electrostatic stochastic wave is investigated analytically. The reaction of the particle back on the wave is not taken into account. One model adopted is a wave, ...

(19831201)A momentum equation for an arbitrary particle species is derived from the Klimontovich equation when the wave amplitude and the background plasma parameters are changing slowly in space and time. The derivation of the ...

(19720301)The Bernstein, Greene and Kruskal stationary states of a four contours waterbag system are discussed in detail. The time evolution of a linearly stable twostream system towards an exact nonlinear stationary state is shown ...

(19730701)The proposal by Watson (1971, UK Patent G6P (G 21 b 3/16) N 1252906) to reduce the cone losses of a plasma in mirror machines depends on creating conditions such that particles with small transverse (with respect to the ...

(19831101)Most Thomson scattering data is analyzed to obtain the electron temperature by finding the best fit to a straight line on a loglinear plot of intensity versus the square of the wavelength shift. The author points the error ...
