ID15B technical details

The beamline was originally a single-purpose beamline dedicated to high resolution inelastic x-ray scattering, but it was reconstructed after the recommendations of last review to suit also for diffraction experiments.

ID15B takes monochromatic radiation (30, 60 or 90keV). It holds high resolution Compton setup (HRC) and 2D-diffraction setup.

The beamline is a side-station, i.e. it cannot receive the white beam. It receives monochromatic beam from a horizontally focusing monochromator located in Optics Hutch 1, 10 m upstream of the experimental hutch. The scattering angle for the monochromator is almost fixed (10% tunebility) by the beamline geometry. This determines the range of available energies. In-vacuum monochromator tank holds three monochromators providing 30, 60 or 90keV radiation. The first two are 40cm long bent Bragg crystals and the third one is a bent Laue-crystal.
