Beamline ID15B is dedicated to the determination of structural properties of solids at high pressure using angle-dispersive-diffraction with diamond anvil cells.
The beam from an in-vacuum U20 insertion-device is focused by vertical and horizontal transfocator and monochromatized by Si(111) Bragg monochromator. The working energy for high pressure experiments is 30 keV with a flux of 1012photons/s at 200 mA. The beam size on the sample is normally about 10x10 µm2.
The scattered radiation is collected by a Mar555 flat panel detector, which has a 430 x 350 mm (555mm diagonal) active area.
A laser spectrometer is available for pressure determination by the ruby fluorescence method.
It is also possible to perform Raman scattering experiments simultaneously.
The beamline is equipped with severalmembrane-type diamondanvil cells (0-60 GPa), a Liquid He cooled cryostat to perform high pressure experiments at low temperatures (down to 10 K), and external resistive heating equipment for high temperatures up to 600 K.
A Nd-YAG laser system is availableexternally for high temperature annealing of samples inside the diamond anvil cell.
