X-RAY RUNS: Apply for Beamtime

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

 

D3: Defects, Distortions, and Dynamics in complex materials

 

Date: June 27 and 28
Organizers: Raymond Osborn (Argonne National Laboratory), Jacob Ruff (CHESS), Katie Silberstein (CHESS)

 

This workshop will address emerging opportunities in high energy single crystal diffraction using next-generation pixel array detectors, as a probe of lattice-coupled effects in quantum materials. This covers both diffuse scattering and weak-peak crystallography. Topics under discussion may include phase transitions, low-dimensional correlations, short-range order, superstructures, charge-density-waves, phonons, frustration, quasicrystals, and strain. We will make the case for a bright high-energy undulator beamline dedicated to efficient mapping of reciprocal space. This workshop will bring together current and prospective CHESS users who can benefit from high dynamic range diffraction, to share results and identify strategic opportunities for future development in terms of detectors, software, beam properties, and high impact experiments. Speakers are encouraged to talk about what experiments they currently perform, how these could be improved by the proposed upgrades, what new sample environments would be most useful to develop, and which critical new experiments might be enabled by these advances.

Speakers: Branton Campbell (Brigham Young University), Patrick Clancy (University of Toronto), Olivier Delaire (Duke University), Bruce Gaulin (McMaster University), Alan Goldman (Iowa State University and Ames Laboratory), Andrew Goodwin (University of Oxford), Sol Gruner (CHESS), Raymond Osborn (Argonne National Laboratory), Daniel Phelan (Argonne National Laboratory)
