X-RAY RUNS: Apply for Beamtime

2017  Nov 1 - Dec 21
2017  Proposal/BTR deadline: 9/1/17

Real-time in-situ x-ray scattering provides a wealth of information useful for understanding chemical reactions and phase transitions in advanced technologies. Careful measurement of solution concentration and crystallization throughout the drying of a solution allows for the control of the way in which the solution to solid phase transformation takes place. The improvement of organic light-emitting diodes and discovery fuel cell energy sources are just a few of the topics collaborators come to CHESS to investigate.

The study of chemical reactions, at times, requires high spatial resolution. X-ray diffraction techniques can probe the crystallographic structures of materials during reactions. Thin films and devices can be studied with grazing-incidence small and wide angle scattering. Additionally, CHESS is equipped with sample environments for studying chemical reactions and for monitoring self-assembly or structural changes, such as occur during thin film deposition and annealing.
