Title: Self-Sustained Oscillations in a Plasma-Wall System with Strongly Inhomogeneous Diffusion of Charged Particles

Abstract

A simple system with a hydrogen plasma confined by a magnetic field parallel to the bounding material wall is considered. The charged particles diffuse out of the plasma, recombine on the wall and return into the plasma volume as neutrals, which are ionized by electrons. It is demonstrated that macroscopic self-sustained oscillations are an intrinsic feature of such a system if the diffusion coefficient of charged particles is strongly inhomogeneous in the plasma.

  • The diffusion of projectiles drifting through a target of strongly coupled dusty plasma is investigated in a simulation. A projectile's drift is driven by a constant force F. We characterize the random walk of the projectiles in the direction perpendicular to their drift. The perpendicular diffusion coefficient D{sub p⊥} is obtained from the simulation data. The force dependence of D{sub p⊥} is found to be a power law in a high force regime, but a constant at low forces. A mean kinetic energy W{sub p} for perpendicular motion is also obtained. The diffusion coefficient is found to increase with W{submore » p} with a linear trend at higher energies, but an exponential trend at lower energies.« less
  • The distribution of energetic charged particles generated by thermonuclear fusion reactions in a field-reversed configuration (FRC) are studied analytically and numerically. A fraction of the charged fusion products escapes directly while the others are trapped to form a directed particle flow parallel to the plasma current. It is shown that the resultant current density produced by these fusion charged particles can be comparable to background plasma current density that produces the original field-reversed configuration in a D--/sup 3/He reactor. Self-consistent equilibria arising from the currents of the background plasma and proton fusion products are constructed where the Larmor radius ofmore » the fusion product is of arbitrary size. Reactor relevant parameters are examined, such as how the fusion reactivity rate varies as a result of supporting the pressure associated with the fusion products. A model for synchrotron emission from various pressure profiles is developed and it is shown quantitatively how synchrotron losses vary with different pressure profiles in a FRC.« less
  • Plasma turbulence and anomalous transport by the electrostatic current diffusive interchange mode are studied by the nonlinear simulation based on the magnetohydrodynamic model. The turbulence is found to have a typical characteristic of subcritical turbulence. The saturation level, as a function of the pressure gradient {del}{ital p}, is confirmed to scale like {vert_bar}{del}{ital p}{vert_bar}{sup 3/2}. This nature holds independent of the ratio {vert_bar}{del}{ital p}{vert_bar}/{vert_bar}{del}{ital p}{sub {ital c}}{vert_bar} where {vert_bar}{del}{ital p}{sub {ital c}}{vert_bar}, is a critical pressure gradient against linear instability. The turbulence-driven transport is also evaluated. The simulation result confirms the theoretical prediction, which is based on the self-sustained turbulence,more » with respect to the nonlinear growth and damping. Both the normal cascade and inverse cascade are essential in establishing the stationary turbulent state. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.« less
  • Methods of the quasilinear theory of plasma stability were used to determine saturation amplitudes and spectralacoustic oscillations in an inhomogeneous plasma in a strong magnetic fieid. The full energy of ion-acoustic oscillations at the saturation stage proved less than that of the thermal motion of the electrons of the plasma by a value of the order of (m/sup e/)/(m/sup i/)/ sup 2//(u/sub 0/)/( ,/sub Te/) (where m/sup e/, m/sup i/ are the masses of the electrons and ions u/sub 0/ and /sub T//sub e/ are the average and thermal velocity of the electrons). The current of particles across the magneticmore » field due to excitation of ionacoustic oscillations is computed. The current in a direction perpendicular to the magnetic field and the gradient of density and temperature, giving rise to diamagnetism of the plasma, and the diffusion current in the direction of the gradient were measured. The ratio of the diffusion due to the excitation of the oscillations under consideration to the diffusion coefficient due to paired collisions proved to be of the order of (m/sup e/)/(m/ sup i/)/sup 2//(u/sub 0./)/( /sub Te/) N/sub D/: (w here N/sub D/ is the number of particies in a Debye sphere). N/sup D/ >> 1; however, since (m/sup e/)/ (m/sup i/) st run. Concent 10/sup -3/ the ratio (D/sup (osc))//(D/sup (st)) / cannot be very great, Under stellarator conditions the value of the diffusion due to excitation of ion-acoustic oscillations is 4-6 orders less than the experimentally observed diffusion and, therefore, the anomalously short lifetime of plasma in the stellarator cannot be explained by excitation of ionacoustic oscillations.
