Radial profiles of ion flow vd(r) are measured with laser-induced fluorescence for cases in which the flow direction is parallel (vd>0) and/or antiparallel (vd

Experimental and theoretical evidence is reported for the existence of discrete modes in the weakly collisional regime of electrostatic ion waves. The decay of time-harmonic perturbations of the ion velocity distribution function is found to be weake

Laser-induced fluorescence in plasmas is shown to be strongly influenced by velocity-space diffusion, under the proper conditions. The induced fluorescence is modeled by a set of coupled rate equations that include the Fokker-Planck operator for each

Cross-field transport of barium test ions is studied in a Q-machine plasma. Test particles are produced and tracked in their motion by an optical tagging method. The comparison between the measured tag signal and a simple theoretical simulation yield

Periodic pulling, the incomplete entrainment of a driven, nonlinear oscillator, is observed experimentally in a relaxation oscillator for the first time. A neon-bulb relaxation oscillator is driven by a chopped, neon-resonant, laser beam. For driving

Chaos in the context of wave-particle interactions has been shown to produce particle acceleration and nonresonant wave absorption. High resolution plasma diagnostics involving laser-induced fluorescence and optical tagging are applied to test the ap

Experiments are presented which demonstrate the conversation of certain integrals of motion during Hamiltonian chaos where the conservation of some of the integrals has been broken by the overlap of resonances. Experimentally, conservation laws are d

Ionic spin polarization by optical pumping is demonstrated as a technique for plasma test-particle diagnostics. “Spin-tagging” is used to observe the magnetized plasma tag-particle transfer function.

Cross-field transport of test ions is investigated in a linear Q-machine plasma. Test particles are created and followed in their motion by an optical tagging diagnostic scheme. Diffusion is demonstrated to be supported by classical mechanisms. When
