Abstract
The liquid flexRIXS endstation is dedicated to resonant inelastic x-ray scattering experiments on liquid samples and gasses in the soft x-ray range. The liquids are injected into the chamber via a liquid jet system whereas gasses and also small amounts of liquids can be investigated using a liquid/gas flow cell. The MCP-based RIXS spectrometer allows for a resolving power of better than 1000.
Highlights
Liquid exRIXS is an endstation for time-resolved and steady-state RIXS measurements on liquid samples and for complementary use at FELs and at BESSY II
Liquid samples are prepared in vacuum as thin jets
The jet freezes after passing the interaction region in a liquid nitrogen cooled trap
Summary
Liquid exRIXS is an endstation for time-resolved and steady-state RIXS measurements on liquid samples and for complementary use at FELs and at BESSY II. The RIXS spectrometer of the end station is a modi ed GRAZE IV (XES 350) with three gratings. These cover the range between 50 and 900 eV. Liquid samples are prepared in vacuum as thin jets (diameter [5-30] μm). Static and time resolved RIXS measurements at liquids and gasses as well as non-linear processes are conducted with this experimental station at BESSY II and FELs. Depending on the X-ray spot size the jet speed in vacuum allows for refreshing the sample in the interaction region with MHz repetition rates. The apparatus is open to collaborative Research at BESSY II and FELs
