This is a practical internship program focused to a basic procedure for crystal structure analysis. It would be particularly suitable for Ph.D. students, Post-Doc and young scientists who are beginners for Rietveld refinements and structure solving. Anyone who would like to improve their knowledge and skills for crystal structure analysis or anyone who is interested in the experiments in spallation neutron sources like J-PARC will also be welcome.

The internship will include the following program.

• Procedure of analysis for powder x-ray/neutron diffraction using GSAS
• An introduction to crystallography (the definition of a crystal, the diffraction process, concept of reciprocal lattice, Bragg’s law, space group, etc...)
• What profile patterns tells us. (lattice constants, atomic coordinates, atomic displacements, crystalline size, preferred orientation, residual stress, etc...)

It is preferable that participants will bring their own laptop computer to install some crystallographic software. GRC can prepare several laptop PCs, if participants do not have one. The number of participants will be limited to 15.
