chemRIXS Layout

NEH 2.2 will host 2 instruments, qRIXS and chemRIXS, that will be placed in series with attention paid to X-ray focal requirements, vacuum compatibility and beam pass-through capabilities.  Dedicated laser delivery infrastructure will be implemented for each instrument, taylored for the specific requirements. 

 Time-tools will be located immediately in front of each endstation for accurate measurement of the relative time between the arrival of x-ray and optical laser pulses.  Intensity fluctuations of the x-ray beam will be monitored on a shot-by-shot basis by a suite of fast single-photon sensitive detectors measuring either the fluorescence or electron yiled from the last 2 beamline mirrors.

The chemRIXS instrument is comprised of a sample chamber, designed with emphasis on soft X-ray spectroscopy experiments on liquid samples.  The instrument is equipped with a suite of detectors allowing for XAS and RIXS/XES measurements.  The endstation is designed to support automated sample transfer via a retractable delivery system.  A sample catcher coupled to a re-circulation system will be implemented.
