Workshop summary and purpose
A workshop on single crystal neutron diffraction will be held at the Spallation Neutron Source at the Oak Ridge National Laboratory (ORNL). It will present invited and contributed talks to showcase cutting edge science and examples where neutron diffraction can make significant contributions; and provide training in neutron structure analysis and sample screening for the preparation of instrument beam-time proposals.
TOPAZ is a high resolution wavelength-resolved Laue diffractometer with a versatile sample environment. Commissioning user experiments have demonstrated successfully the instrument capability for structural study of a vitamin B12 derivative, ion distribution in Li-ion battery materials, order and disorder in shape memory intermetallics, magnetic phase transition in multiferroic single crystal and functional thin films. The workshop is directed towards experienced neutron diffraction users and new users alike and encourages members to highlight their research and interest in structure analysis and investigation. The workshop will give opportunity to bring your own single crystal and screen sample quality and scattering power on TOPAZ @ room temperature, to evaluate data collection time and quality for an anticipated experiment. Finally, an opportunity to compose a proposal for neutron beam time (http://neutrons.ornl.gov/users/proposals.shtml) with staff will be provided in the framework of the workshop. The workshop format is well suited for researchers to contribute by showcasing their research and bring their research group or graduate student, who would like to test a single crystal sample. User access training for the ORNL neutron scattering facility will be included. It will be valid for future experiments.
To present your research, please submit a title with 100 word abstract by July 30, 2011.
The goal of this workshop is to showcase science that is possible on the TOPAZ single crystal neutron diffractometer and to bring science communities together consisting of experienced and new users to explore the use of neutron single crystal diffraction and formulate a concise report for future improvements and upgrades necessary to bring TOPAZ to its full potential.
The meeting is structured into the following principle topics in six sessions:
- Science presentations and discussions, poster session
- Highlight TOPAZ capabilities, experiment and sample environment conditions
- Show the new data collection and data reduction software & hands on data analysis
- Screen user samples and collect short single crystal neutron data set
- Guided preparation of beam time proposals
- Discuss future role TOPAZ needs to advancement TOPAZ science
- Tour SNS
