- ID15B - High Pressure Diffraction Beamline
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 1012 photons/s at 200 mA resulting in typical exposure times of 1 sec. The beam size on the sample is about 30 x 30 µm2 but can be made as small as 5 x 5 µm2 for megabar pressure experiments.
