Barrel Spectrometer

The "barrel" spectrometer - CHESS engineered large solid angle dispersive spectrometer allows an entire x-ray emission spectrum to be collected at once.  This spectrometer is ideal for time-resolved studies and rapid collection of two-dimensional data.

Beamline Status

Description: The PIPOXS beamline will be optimized for x-ray spectroscopic studies of geometric and valence electronic structure in catalytic system and functional materials.
Lead Scientist: Christopher Pollock

Capabilities under development:
  • Wide incident energy range enables access to all K-edges from potassium to calcium and all L-edges from lead to antimony
  • Temperature control from 10 K to room temperature and above is available;
  • In-hutch gas handling allows operando reactions using gaseous reactants to be monitored;
  • Beamline-based microfluidic system will enable observation of solution-phase chemical reactions on the milliseconds - seconds timescale;
  • Two-color scanning spectrometer allows for x-ray emission data collection from two elements simultaneously;
  • Dispersive spectrometer will allow continuous collection of an entire emission spectrum;
  • Operando XAS and XES experiments are available for electrochemical cells
Beamline capabilities: Non-resonant x-ray emission spectroscopy (Kα, Kβ, valence-to-core); X-ray absorption spectroscopy (XAS) and extended x-ray absorption fine structure (transmission and fluorescence); High energy resolution fluorescence detected XAS; Resonant x-ray emission / resonant inelastic x-ray scattering (at ~1 eV resolution)
Photon Energy Range: 4.0 - 30 keV for Si(111);
7.0 - 58 keV for Si(311);
Resolution:  
Spot Size: After spring 2020, spot size will be adjustable from 2 mm (h) x 1 mm (v) down to 50 microns x  100 microns
