要旨:
A novel experimental setup is presented for resonant inelastic X-ray scattering
investigations of solid and liquid samples in the soft X-ray region for studying
the complex electronic configuration of (bio)chemical systems. The uniqueness
of the apparatus is its high flexibility combined with optimal energy resolution
and energy range ratio. The apparatus enables investigation of chemical
analyses, which reflects the chemical imprints. The endstation is composed of a
main sample chamber, a sample holder for either solid or liquid jet delivery
system, and a soft X-ray grating spectrometer for 210–1250 eV with a resolving
power of
1000. It combines for the first time liquid jet technology with a soft
X-ray spectrometer based on the variable line spacing principle. This setup was
commissioned at the soft X-ray beamline P04 at PETRA III of the Deutsches
Elektronen-Synchrotron in Hamburg which is currently the most brilliant
storage-ring-based X-ray radiation source in the world. The first results of liquid
and solid samples show that this setup allows the detection of photons across an
energy range of
300 eV. This covers simultaneously the emission lines of life-
important elements like carbon, nitrogen and oxygen in a shot-based procedure.
