Experimental diagnosis of plasma electron density with an x-ray laser probe

An application demonstration of diagnosing electron density gradient distributions of CH laser-plasma by x-ray laser was reported. Using an saturated Ni-like Ag x-ray laser as the probe beam and the moire deflection method, A legible moire deflectogram including the plasma electron density information was recorded. Analysis of the deflectogram gave a peak electron density of 1.1x10(21)cm(-3), and this value had been higher than the critical density.
