Overview
Beam line 11-3 is a fixed energy (E = 12.7 keV, λ = 0.9763 Å) wiggler side station dedicated to wide-angle X-ray scattering techniques (WAXS). The beam line specializes in grazing-incidence geometry measurements, but transmission geometry measurements are also available upon request. The high flux of the instrument paired with a Rayonix MX225 CCD area detector enables rapid data acquisition across variable q-ranges for in situ/operando X-ray scattering measurements.
This instrument supports a broad array of topics in material science, chemistry, physics, and environmental science. Notable applications include structural characterization of:
- Photovoltaics/solar cells
- Batteries (pouch cells) and electrodes
- Polymers (membranes, thin films, upcycling, catalytic decomposition)
- Organic and inorganic semiconductors
- Microelectronics and quantum devices
- Sorbents for gas capture, storage, and separations
Many of these materials can be examined in situ or operando with facility supported or user provided sample environments. Contact the beam line scientist or engineer to discuss the feasibility of user provided sample environments.
