Ultrafast X-ray Absorption Spectroscopy using Laser-Driven Electron X-ray Sources (LEXS)

چکیده
A laser driven electron x-ray source (LEXS) using a high repetition rate, terawatt laser system is described. The laser system has adopted design features that make it more suitable for the generation of hard x-ray pulses. These features include a simplified pumping scheme to reduce cost and complexity, a λ/4 broadband regenerative amplifier to support high-energy, short optical pulse generation, and a 50-Hz repetition rate to achieve both a desired pulse energy and a simple compressor design. Preliminary results on x-ray generation using this system are reported. A new method, ultrafast selected energy x-ray absorption spectroscopy (USEXAS), based on this LEXS is discussed.

Ultrafast Selected Energy X-ray Absorption Spectroscopy (USEXAS) with a Laser-Driven X-ray Source
A laser driven electron x-ray source (LEXS) emitting tungsten Lα lines has been built based on a high repetition rate, terawatt laser system. The Lα characteristic lines overlap with the absorption edge of Ni near 8333 eV. Using this x-ray source, the x-ray absorption spectra near the absorption edge of different Ni compounds have been measured. We term this new method “ultrafast selected energ...
متن کاملLaser plasma x-ray source for ultrafast time-resolved x-ray absorption spectroscopy
We describe a laser-driven x-ray plasma source designed for ultrafast x-ray absorption spectroscopy. The source is comprised of a 1 kHz, 20 W, femtosecond pulsed infrared laser and a water target. We present the x-ray spectra as a function of laser energy and pulse duration. Additionally, we investigate the plasma temperature and photon flux as we vary the laser energy. We obtain a 75 μm FWHM x...

High-resolution X-ray absorption measurements (with an accuracy of +/-0.3 eV) of ZnSO(4) (aq) were performed with ultrafast selected energy X-ray absorption spectroscopy (USEXAS) using a laser-driven tungsten target X-ray source. The results were used to determine the absolute spectral positions of characteristic emission lines. By comparing these positions to those predicted for the line emiss...

We report the generation of ultrashort, hard-x-ray pulses from a liquid mercury target irradiated by 5 kHz laser pulses. The new x-ray source is designed for time-resolved x-ray absorption spectroscopy as well as imaging applications. This marks the first laser-driven plasma x-ray source that continuously recycles the target material, facilitating maintenance-free operation. Theoretical calcula...

The rapidly growing ultrafast science with X-ray lasers unveils atomic scale processes with unprecedented time resolution bringing the so called "molecular movie" within reach. X-ray absorption spectroscopy is one of the most powerful x-ray techniques providing both local atomic order and electronic structure when coupled with ad-hoc theory. Collecting absorption spectra within few x-ray pulses...
