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.
