Temperature Determination in X-ray Laser Plasmas by Thomson Scattering

Abstract

One of the outstanding uncertainties in modelling x-ray laser experiments lies in determining the actual plasma parameters which crucially affect the prediction of laser performance. Electron temperatures are commonly inferred experimentally from x-ray emission spectra or from the Landau damping cutoff of stimulated Raman scattering, neither of which directly measures the temperature with sufficient precision at the location where lasing occurs.
