Schematic of the experimental arrangement for the Al -shell line measurement.
Typical x-ray spectrum from the aluminum plasma generated by high power laser.
Evolution of x-ray line intensities vs the laser intensities. The x-ray intensities are normalized by the incident laser energy in Joule and in units of Joule per solid angle.
Evolution of x-ray intensity ratios of the line to the line and the intercombination line to the line vs the laser intensities.
Calculated x-ray intensity ratio of the to lines as a function of electron temperature for two plasma densities: and using the collision-radiative (CR) model.
The derived electron temperatures as a function of laser intensities.
The derived electron densities from the measured x-ray intensity ratios of the intercombination to resonance lines as a function of the laser incident intensities.
