Crystallography under high pressure using synchrotron radiation

International audienceThis review provides an overview of high pressure crystallography using synchrotron radiation. Such experiments concern most of the scientific domains (Physics, Chemistry, Biology, Earth Science, Material Science...). After a description of the most used high pressure apparatus and of the different techniques of diffraction, adapted to high pressure environment, we present few examples of scientific results, selected from these different scientific domains. The perspective opened by recent experimental developments is also discussed
