Single-shot multi-keV X-ray absorption spectroscopy using an ultrashort laser-wakefield accelerator source
Original language description
Single-shot absorption measurements have been performed using the multi-keV x-rays generated by a laser-wakefield accelerator. A 200 TW laser was used to drive a laser-wakefield accelerator in a mode which produced broadband electron beams with a maximum energy above 1GeV and a broad divergence of ≈15 mrad FWHM. Betatron oscillations of these electrons generated 1.2 × 106 photons/eV in the 5 keV region, with a signal-to-noise ratio of approximately 300∶1. This was sufficient to allow high-resolution x-ray absorption near-edge structure measurements at the K edge of a titanium sample in a single shot. We demonstrate that this source is capable of single-shot, simultaneous measurements of both the electron and ion distributions in matter heated to eV temperatures by comparison with density functional theory simulations.
