Ion Turbulence in a CO2-Laser-Plasma Interaction Experiment
Abstract
Ruby-laser Thomson scattering have been used to measure ion density fluctuations in a CO2-laser-heated gas-target plasma. Nonthermal enhancements of > 104 have been observed for kλD~0.5 implying δnn>0.1. Ion fluctuations of this magnitude may be giving rise to enhanced absorption of laser radiation in the plasma.
