PSICHE is a beamline dedicated to high pressure X-ray diffraction (both with monochromatic beam and white beam) and to tomography in absorption contrast at high energy (20-50 keV). Experiements can be performed coupling high pressure and high temperature (resitive and laser heating) or low temperature (in an He cryostat). Different pressure are available: diamond anvil cell, Parie-Edinburgh cell and multi-anvil large volume cell.

The beamline is installed on a short straight section of the SOLEIL (I03c), The source is a under vacuum multi-pole wiggler (2.1 T) which delivers a white beam with a large photon energy range (15-100keV). 
To perform the various experiments planned on the beamline, 4 different operating modes will be implemented.

  1. White beam mode : energy dispersive x-ray diffraction 
  2. Focused monochromatic mode : angular dispersive x-ray diffraction 
  3. Unfocused monochromatic mode : high energy resolution tomography 
  4. Unfocused monochromatic mode : high flux tomography

The beamline is divided in two hutches. The first hutch accomodates the optic but is also used for the white beam experiments (mode 1). The second one is the monochromatic experiment hutch (modes 2,3,4).
