Macromolecular Crystallography @HZB
The HZB-MX Facility consist of three seperate beamlines, each of them with a dedicated endstation. Beamlines 14.1 and 14.2 are dedicated to multi-wavelength-anomalous dispersion (MAD) phasing methods operating with a tuneable energy between 5.5-15.5 keV (2.25 to 0.75 Å), which cover the absorption edges of most commonly used heavy atom derivatives. Beamline 14.3 is a fixed energy station operating at 13.87 keV (0.89 Å).
State-of-the-art detector technologies, including the PILATUS 6M (BL14.1) and PILATUS3S 2M (BL14.2) detectors (Dectris, Switzerland), enable high quality and rapid data collection. Fast and reliable sample changing is realized by automated samples changing robots CATS and G-ROB employed on both beamlines 14.1 and 14.2, respectively.
The infrastructure adjacent to the experimental end stations offers excellent facilities for users of the beamlines and includes office space, a sample preparation lab, a biology lab (safety level 1), and computing resources.
