Table top ultra-fast x-ray spectroscopy
A large part of our research efforts is aimed to develop table-top systems capable of measuring x-ray spectra with sufficient time-resolution to perform these studies in-house. We have developed a x-ray plasma source based on a water that produces x-rays from the XUV to beyond 80 keV. We have developed detection technology that is capable to analyse spectra from x-ray absorption and x-ray emission with extreme efficiency in the range from >300eV to 10 keV with better 3eV at 6keV, which is sufficient for many applications. Our secret is the use of direct detection, energy dispersive schemes using CCD's and Microcalorimeter. A particular focus of these setup is the spectroscopy in the "tender" x-ray range from 1keV to 5keV including the science of sulfur and phosphor based polymers.
