High performance streaked X-ray spectrometer for research of laser-produced plasmas

In order to mitigate the effect of the strong electromagnetic pulse, which produces laser-plasma interactions, we designed a new streaked X-ray spectrometer (SXS) enclosed within a well-sealed, electromagnetic interference-free cavity. The SXS can cover a wide selection of spectral windows using interchangeable Bragg crystals and by appropriate adjustment of the Bragg angle. The SXS has been used to observe time-resolved X-ray spectrum in the 2.5 keV to 3.5 keV photon-energy range, resulting in a demonstrated spectral resolution of about 13 at 2960 eV with a time resolution of 10 ps. The observed time and spectral resolutions demonstrate the applicability of the SXS for studies of laser-produced plasmas.
