Technical details

Beamline ID27 has been operating since 2006 in replacement of ID30 (an instrument which was mostly dedicated to white beam experimentation). This instrument is fully optimised for monochromatic high-resolution XRD in order to address the most exciting and challenging questions related to science at very high pressures. The beamline can easily accommodate very complex sample environments such as a double-sided laser heating system, Paris-Edinburgh press and HP helium cryostat. Techniques available are powder and single-crystal microdiffraction, X-ray microfluorescence, and in situ Raman scattering.
