Thomson scattering diagnostic of solid density plasmas using x-ray lasers

In this article, we demonstrate through calculations and theoretical analysis the first application of an x-ray laser for probing hot, high-density plasmas (ne⩾1023 cm−3) using a Ni-like transient collisional excitation x-ray laser as a probe. Theoretical predictions are used to diagnose the electron temperature in short-pulse (500 fs) laser-produced plasmas. The threshold power of the x-ray probe is estimated by comparing theoretical scattering levels with plasma thermal emission. The necessary spectral resolution of the instrument sufficient for resolving electron temperature is given. Effects of the electron heat flow on the ion-acoustic fluctuation spectra are presented. The outlook for these and next generation experiments are discussed.
