KeV spectroscopic diagnostic for the performance of Ni-like x-ray lasers

摘要

In order to understand the improved performance of Ni-like x-ray lasers driven by a double 75 ps laser pulse, a systematic study on keV emission from plasmas generated by different drive pulse configurations has been made. Significant changes in temperatures and relative abundances of the ionisation stages for different drive pulse configurations have been found with the help of numerical simulations.
