Towards structural dynamics research with ultrashort pulse lasers and synchrotron radiation

The authors present a new technique to record single x-ray pulses in time-resolved x-ray absorption spectra spectroscopy (XAS) expts. at low frequencies around 1 kHz compared to the multibunch repetition rate at synchrotron radiation storage rings of several hundred MHz. This scheme of electronic gating of the multibunch train is applied to record high-quality EXAFS spectra. Further measurements show that this scheme permits the authors to record high-quality x-ray absorption spectra with a noise level <3 * 10-3. The achieved results imply the utility of this method with current synchrotron radiation sources. [on SciFinder (R)]
