Abstract

Grid-launched IAWs are studied in the LMP-Q machine by application of Laser Induced Fluorescence techniques. The ion dielectric response contained in the perturbed ion velocity distribution yields an identification of wave propagation characteristics as well as calibration of wave amplitude. Optical tagging is utilised to construct the ion phase space trajectories via time of flight spectral analysis. The wave-particle interaction produces orbit perturbations for resonant ions, even when the wave exhibits linear properties. In the strong excitation regime, time resolved and spatially scanned measurements of the ion velocity distribution in the wave field demonstrate features of ballistic propagation. The experimental techniques are discussed and results of a Hamiltonian analysis are presented.
