A TABLE-TOP APPARATUS FOR TIME-RESOLVED X-RAY ABSORPTION AND EMISSION SPECTROSCOPY USING AN ARRAY OF AN X-RAY MICROCALORIMETER SENSORS

We present a table-top apparatus for time-resolved x-ray absorption and emission spectroscopy consisting of a laser plasma x-ray source, a microcalorimeter array x-ray spectrometer, and an interaction region where samples of interest can be excited by ultraviolet/visible/infrared light pulses and then probed after a controllable delay by x-ray pulses. X-rays are transported from the laser plasma source to the interaction region using a focusing x-ray optic. Transmitted or emitted x-rays from the samp1e are detected using the microcalorimeter x-ray spectrometer depending on its orientation relative to the probing x-ray beam.
