P21.1 Broad band diffraction

 


       At beamline P21.1 a set-up for high-energy x-ray diffraction is utilized for studies of single crystals, amorphous materials liquids and nanocrystalline matter. The beamline comprises a broad band monochromator, a heavy load sample stage and a detector stage with both point and area detectors.



       Beamline P21.1 resides at the 3rd generation synchrotron radiation source PETRA III in Hamburg, Germany, in the newly erected Hall 48g.


       P21.1 is an undulator beamline, with a fixed angle of a single-bounce monochromator. Thus, energies of 52keV, 85keV, and 100keV can be utilized. The beam size is about 1 x 1 mm2 with the option to focus the beam in the vertical.


       In the experimental hutch, the heavy load diffractometer can carry loads up to 600 kg with a vertical rotation axis and a double tilt stage. In addition an Eulerian cradle can be mounted for larger sample movement. The point detector setup uses an analyzer crystal with tuneable rocking width to adjust the resolution to the sample scattering properties. The point detector can remotely be exchanged against 2d-detectors of different sizes.
