Overview
Beamline 1-5 is a materials science beamline that has been used for a host of science areas, for example polymer morphology during deconstruction, nanoparticle synthesis, catalyst support materials, and hydrated skin samples. Beamline 1-5 is a bend magnet end station focused on small-angle x-ray scattering (SAXS) measurements, but with the possibility of also doing wide-angle x-ray scattering (WAXS). It can also be configured for simultaneous SAXS/WAXS. BL1-5 is equipped with two area detectors: Dectris Pilatus 1M (SAXS) and Dectris Pilatus 100K (WAXS). The beamline is available in two standard configurations: 1- and 3-meter sample-to-SAXS detector distances. The WAXS detector is typically capable of reaching a minimum q value of 1.2 Å-1 for either of the configurations.
The beam line accommodates x-ray energies in the range of 8-17 keV. There are several sample environments available.
The current user base consists of both internal and external users and can be grouped into the following scientific research areas:
- Batteries
- Polymer upcycling
- Microelectronics/flexible electronics
- Separations
- Gas capture and storage
- Critical materials
