A broadband laser plasma X-ray source for application in ultrafast chemical structure dynamics

In English A plasma source free from characteristic emission lines is described, based on laser irradiation of a
water jet in a helium atmosphere. Various key aspects of the laser interaction are presented along
with practical characterization of the observed isotropic ~4–10 keV x-ray emissions,
measurements of which indicate subpicosecond duration. Observations are consistent with a vacuum
heating plasma mechanism at the helium-water interface and indicate strong potential for in-house
ultrafast chemical structure dynamics application when coupled to contemporary detector
developments.
