Enhancements observed in the scattered light spectra of a carbon arc plasma Churchland, Mark Trelawny


The spectrum of Ruby laser light scattered from a carbon arc plasma has been studied. The temperature of the plasma is shown to be much hotter than was previously reported. Enhancements in the spectrum of light scattered were observed. Their frequencies were shown to be a sensitive function of the plasma wave scale length K, and the plasma density and temperature. A model is constructed which produces enhancements in the theoretical scattered spectra at particular frequencies. This model is fitted to the observed spectra; this fitting is discussed.
