This is a practical internship program focused on a basic procedure for synchrotron in situ X-ray diffraction experiment under high pressure and high temperature. It would be particularly suitable for Ph.D. students, Post-Doc and young scientists who are beginners for in situ X-ray diffraction experiment under high pressure and high temperature. The experiment will be conducted using a large volume high pressure apparatus (MA8-type (Kawai-type) apparatus), SPEED-1500 or SPEED-MkII in SPring-8. Anyone who would like to know how to conduct in situ X-ray diffraction experiment using Kawai-type apparatus in SPring-8 or anyone who has a plan to do such kind of experiment in SPring-8 will be also welcome.

The internship will include the following program.

1. Lecture for synchrotron in situ X-ray diffraction experiment under high pressure and high temperature
2. Preparation of high pressure cell assembly
3. In situ X-ray diffraction experiment under high pressure and high temperature
4. Analysis for the obtained diffraction data

In this internship, we will observe olivine - wadsleyite transformation in Mg2SiO4, and then collect the P-V-T data of wadsleyite in wide pressure and temperature range. Using the data, we will determine the P-V-T equation of state for wadsleyite. The number of participants would be limited up to 15.
