The Role of Small-Angle X-ray Scattering in Materials Science

Chairs: M. Toney, J. Pople
Admin Contact: Jackie Robleto
Wed. Oct. 19th 9am - 5pm   
Location: SLAC Bldg. 40, Orange Conference Room

This will be a hands on workshop with intent to demonstrate the burgeoning applicability of small-angle x-ray scattering (SAXS) resulting from the expansion of research and development on the nanoscale. The day will begin with presentations, briefly showing the techniques involved in SAXS in Materials Science and more closely focusing on current experimental data at the forefront of research which demonstrate the power of SAXS capabilities. The presentations will be semi-formal, with questions and discussion encouraged. Attendees will then move onto the beamline floor to gain hands-on control of configuring the SAXS beamlines (Beamlines 1-4 and 4-2 will be utilized for this purpose) and collecting and analyzing data. New software recently developed for data analysis with be demonstrated. This practical aspect of the workshop will highlight both the techniques involved in SAXS data collection, reduction and analysis as well as identifying the limitations of existing beamline facilities. A final presentation will outline suggestions for a new Materials Science beamline at SSRL which can overcome those limitations and advance the capabilities that SSRL is can provide to the Materials Science community.
