Abstract:
A laser plasma was generated by pulses of ~5×1015 W/cm2 intensity and τ~10–10 sec duration. The x-ray emission spectra of this plasma were recorded in the spectral range 3–18 Å. The apparatus employed made it possible to record the spectrum produced by a single laser flash and its resolving power was high (λ/Δλ~5000). The relative intensities of the lines due to helium-like and hydrogen-like ions were used in the determination of the electron temperature Te and electron density Ne in the plasma. The spatial distribution of the x-ray emission of a magnesium plasma was determined with a resolution of 25 μ. The laser radiation was focused on a plane target and in a recess. In both cases the values of Te, Ne, and of the Stark and Doppler broadenings of several lines (Te was found from the relative intensities of the lines and Ne from the relative intensities and Stark broadening) were determined as a function of the distance to the target.
