(19861001)Temporally and spectrally resolved omega 0/2 harmonic emission and stimulated Raman scattering has been observed from thin foils irradiated by double pulse of 0.53 mu m laser light. Asymmetric omega 0/2 spectrum from the ...

(19970901)The crash of the temperature profile associated with a propagating transport bifurcation between the Lmode and the magnetic braiding mode (Mmode) in a tokamak plasma is presented. The magnetic braiding mode is induced ...

(19990301)Pressure driven curvature instabilities at the boundary of a tokamak plasma are studied. First, threedimensional turbulence simulations are presented including the case where magnetic field lines are stochastic. Three ...

(19860101)An equation describing the evolution of 2D inhomogeneous magnetized plasma has been derived. In the cold ion case, it is merely a Euler equation or convective cell equation. There is a solitary flute vortex solution to ...

(19930501)A 2D fullwave simulation of ordinary mode propagation has been developed in an effort to model effects seen in reflectometry experiments but not properly explained by 1D analysis. The geometric falloff of the fields, ...

(19970301)The response of a radial correlation reflectometer to turbulent plasma fluctuations in a tokamak/stellarator is studied using a twodimensional (2D) physical optics/distorted surface model. Reflectometer phase and power ...

(19891201)The large scale hydrodynamics of laser accelerated thin disks (foils) are studied numerically using a 2D, evolutionary Lagrangian fluid code. The laser and target parameters considered are relevant to direct drive laser ...

(19990601)We show that it is possible to measure the parallel and the perpendicular flow in a strongly magnetized plasma, using a probe with two current collecting surfaces, inclined with respect to the magnetic field. The method ...

(19841201)An analytical method is described to extend an existing equilibrium model of a straight cylindrical plasma column with elliptic crosssection, traversed by a uniform axial current, and surrounded by a vacuum. This model ...

(19891001)A simple analytic model for the ablation driven by thermal radiation is presented for the case when the flow behind the ablation front is retarded. Scaling laws for the mass ablation rate and the pressure are obtained and ...

(19860801)A theoretical model is presented describing the spatial structure and scaling laws for the ablative corona generated by the incidence of an intense light ion beam pulse on a spherical pellet. This treatment differs, from ...

(19850301)The ablative, quasisteady expansion flow of a plasma generated by impinging a pellet by an intense light ion beam pulse is analysed. Profile of beam density and velocity and plasma density, velocity, and temperatures as ...

(19911101)A simple analytical mode for the implosion of very thin spherical shell targets filled with fuel gas is developed. The shock trajectory in the fuel is described consistently with the shell acceleration, and two dimensionless ...

(19991001)New features of the spacetime evolution of the internal transport barrier (ITB) were highlighted during recent JT60U reverse shear (RS) experiments. An ITB evolution in RS plasmas is often a combination of the fast ...

(19880501)The absorption of oblique extraordinary waves in the electron cyclotron frequency range is analysed by means of a wavedynamical scheme in hot high density plasmas. Strong wave damping is found for densities that largely ...

(19880101)The authors discuss two aspects of the theory of radio frequency heating of tokamaks. The first is the development of a simplified mathematical treatment of ion cyclotron absorption and its application to a study of the ...

(19991201)We review the problem of plasma penetration of astrophysical magnetospheres, focusing on close binary stellar systems in which the Roche lobe overflow occurs. We point out that the accretion stream can penetrate the ...

(19891001)A simple reduction of magnetohydrostatics to a partial differential equation involving two functions has been achieved. Appropriate specialization of the latter is shown to lead to new solutions to the original equation.
