Course: 4th Canadian Powder Diffraction Course Dates: Friday May 25th and Saturday 26th 2001 Location: University of Waterloo, Waterloo, Ontario, Canada Target audience: We aim to give a firm foundation in powder diffraction techniques. In the past there has been a mix of industry and academic participants. Anybody who wishes to improve their knowledge of powder diffraction is welcome. X-ray and neutron powder diffraction will be covered. In the past we have had participants from many disciplines including physics, chemistry, materials science and mineralogy. Topics: There will be introductions to Rietveld analysis methods, indexing procedures and programs, linewidth analysis methods and their relation to microstructural information. In addition, there will be talks on contrast changing/resonant scattering at synchrotron sources and rigid body constraints in refinements. Speakers: Bob Von Dreele (Los Alamos, USA), Angus Wilkinson (Georgia Tech, USA), Robin Shirley (University of Surrey, UK), Davor Balzar (NIST-Colorado, USA), Ian Swainson (NRC, Canada). Costs: We aim to keep costs as low as possible to increase access. However, there are a limited number of places. Registration is just Cdn$150 for non-students (ca. US$97.50) and Cdn$125 for students (ca. US$81.25). Accommodation is available in residence at the University of Waterloo from as low as Cdn$28.90 (ca. US$18.80) +taxes per person per night. On-line registration and further information: http://neutron.nrc.ca/waterloo.htm Format: The course consists of a series of talks in the mornings of the two days, followed by practical sessions through both afternoons which will be run on PCs. "Standard" problems will be available for students to practice with, but participants are encouraged to bring their own problems to discuss. The Rietveld components of the course will be chiefly taught through GSAS, but the concepts are applicable to all Rietveld codes. Participants can bring the codes with which they are most familiar to work on their own problems. The University of Waterloo is 1-1.5 hours from Toronto airport. For those flying, lower airfares are generally available with a Saturday overnight stay. The course is open to all who wish to attend: the last time this course was offered, approximately 60% of partipants were from Canada and 40% from the USA. Acknowledgment: We are grateful to the Dean of Science and Chair of Physics of the University of Waterloo, and the Canadian Institute for Neutron Scattering for financial support.
