Shear-Limited Test Particle Diffusion in 2-Dimensional Plasmas ( Book )
1 edition published in 2002 in English and held by 1 library worldwide
Measurements of test-particle diffusion in pure ion plasmas show 2D enhancements over the 3D rates, limited by shear in the plasma rotation omega epsilon (r). The diffusion is due to "long-range" ion-ion collisions in the quiescent, steady-state Mg+ plasma. For short plasma length Lp and low shear S (equivalent to) r partial derivative omega epsilon/partial derivative r, thermal ions bounce axially many times before shear separates them in theta, so the ions move in (r, theta) as bounce averaged "rods" of charge (i.e. 2D point vortices). Experimentally, we vary the number of bounces over the range 0.2 </= N(sub b) </= 10,000. For long plasmas with N (sub b) </= 1, we observe diffusion in quantitative agreement with the 3D theory of long-range E x B drift collisions. For shorter plasmas or lower shear, with N(sub b)> 1, we measure diffusion rates enhanced by up to 100X. For exceedingly small shear, i.e. N(sub b)>/= 1000, we observe diffusion rates consistent with the Taylor-McNamara estimates for a shear-free thermal plasma. Overall, the data shows fair agreement with Dubin's new theory of 2D diffusion in shear, which predicts an enhancement of D(sup 2D)/D(sup 3D) N(sub b) ^ N(sub b) up to the Taylor-McNamara limit
Landau Damping of Electron Plasma Waves in the Linear and Trapping Regimes ( Book )
1 edition published in 2002 in English and held by 1 library worldwide
Linear Landau damping and nonlinear wave-particle trapping oscillations are observed with m(sub theta) = 0 standing plasma waves (Trivelpiece-Gould modes) in a trapped pure electron plasma. The measured linear damping rate (10 (exp -3 </^gamma/omega </^ 10 (exp -1) agrees quantitatively with Landau damping theory for moderate plasma temperatures (1 <T <3 eV), and exceedingly low wave amplitudes (delta n/n <10 (exp -6). At larger amplitudes, the wave initially damps at the Landau rate, then develops trapping oscillations at frequency ohm(sub tr), causing the effective damping rate to decrease with amplitude as first predicted by O'Neil in 1965. For comparison, the measured damping rate is observed to decrease dramatically when the resonant particles are eliminated by truncating the nominally Maxwellian velocity distribution
Thermal Excitation of Trivelpiece-Gould Modes in a Pure Electron Plasma ( Book )
1 edition published in 2002 in English and held by 1 library worldwide
Thermally excited plasma modes are observed in trapped, near-thermal-equilibrium pure electron plasmas over a temperature range of 0.05 <T <5 eV. The measured thermal emission spectra together with a separate measurement of the wave absorption coefficient uniquely determines the temperature. Alternately, kinetic theory including the antenna geometry and the measured mode damping (i.e. spectral width) gives the plasma impedance, obviating the reflection measurement. This non-destructive temperature diagnostic agrees well with standard diagnostics, and may be useful for expensive species such as anti-matter
