Liquid Jet End Station (Open Access)

Based on a differentially pumped liquid jet system design, the LCLS liquid jet end station (LJE) is equipped with a newly commissioned X-ray emission spectrometer. The varied line-space plane grating spectrometer is optimized to operate for detection from 250 eV to 2000 eV with a resolving power of 1500 to as high as 3000 at lower energies.  The LJE can support various time-resolved pump-probe X-ray emission and/or X-ray absorption experiments examining the ultrafast dynamics for an array of liquid chemistry studies and investigating valence electronic structure and the chemical state for chemically and biologically relevant molecular dynamics. Additionally, X-ray induced radiation chemistry can be investigated through femtosecond time resolved X-ray-pump/optical-probe spectroscopy.

The endstation is in use at LCLS and BESSY-II (Berlin, Germany). Complementary experiments at BESSY are encouraged. Please contact us for more information. For further reading a description of the setup is published:
