PSICHÉ (Pression Structure Imagerie par Contraste à Haute Énergie) : this beamline is dedicated to x-ray diffraction under extreme conditions (pressure-temperature) and to tomography by absorption contrast at high energy (20-50 keV).
The PSICHÉ 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).
