Energetic Electron Transport in Magnetic Fields with Island Chains and Stochastic Regions
E G Kostadinova, D M Orlov, M Koepke +2
This paper investigates energetic electron transport in magnetized toroidal plasmas with magnetic fields characterized by island chains and regions of stochastic field lines produc…
Measurement of wave-particle interaction and metastable lifetime using laser-induced fluorescence
F. Chu, F. Skiff
Extensive information, such as ion temperature and wave-particle interactions, can be obtained by direct measurement of ion distribution functions using laser-induced fluorescence…
Determining Metastable Ion Lifetime and History through Wave-Particle Interaction
F. Chu, F. Skiff
Laser-induced fluorescence (LIF) performed on metastable ions is frequently used to probe the dynamics of ground-state ion motions in many laboratory plasmas. However, these measur…
FPGA based demodulation of laser induced fluorescence in plasmas
Sean Mattingly, Fred Skiff
We present a field programmable gate array (FPGA)-based system that counts photons from laser-induced fluorescence (LIF) on a laboratory plasma. This is accomplished with FPGA-base…
A technique for plasma velocity-space cross-correlation
Sean Mattingly, Fred Skiff
An advance in experimental plasma diagnostics is presented and used to make the first measurement of a plasma velocity-space cross-correlation matrix. The velocity space correlatio…
Velocity space degrees of freedom of plasma fluctuations
Sean Mattingly, Fred Skiff
We present the first measurements of a plasma velocity-space cross-correlation matrix. A singular value decomposition is applied to this inherently Hermitian matrix, and the relati…
Analysis of Magnetic Fields in Inertial Alfven Wave Collisions
Dereth J. Drake, James W. R. Schroeder, Brian C. Shanken +5
Turbulence in astrophysical and space plasmas is dominated by the nonlinear interaction of counterpropagating Alfven waves. Most Alfven wave turbulence theories have been based on…
Alfven Wave Collisions, The Fundamental Building Block of Plasma Turbulence III: Theory for Experimental Design
G. G. Howes, K. D. Nielson, D. J. Drake +4
Turbulence in space and astrophysical plasmas is governed by the nonlinear interactions between counterpropagating Alfven waves. Here we present the theoretical considerations behi…
Alfven Wave Collisions, The Fundamental Building Block of Plasma Turbulence IV: Laboratory Experiment
D. J. Drake, J. W. R. Schroeder, G. G. Howes +4
Turbulence is a phenomenon found throughout space and astrophysical plasmas. It plays an important role in solar coronal heating, acceleration of the solar wind, and heating of the…
Toward Astrophysical Turbulence in the Laboratory
G. G. Howes, D. J. Drake, K. D. Nielson +3
Turbulence is a ubiquitous phenomenon in space and astrophysical plasmas, driving a cascade of energy from large to small scales and strongly influencing the plasma heating resulti…
