Welcome to the pages of the MX-group at BESSY-II

The group is located at the Wilhelm-Conrad-Röntgen Campus of the HZB in Berlin-Adlershof. It is responsible for the operation, maintenance and development of three synchrotron beamlines for macromolecular crystallography at the BESSY-II electron storage ring.

Beamlines 14.1 and 14.2 are dedicated to multi-wavelength-anomalous dispersion (MAD) phasing methods operating 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 enable high quality and rapid data collection.

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. And of course, the competent BESSY-MX crew will assist you before and during your beamtime. The success of the BESSY-MX beamlines is documented by numerous PDB entries from experimental beamtime of more than fifty international user groups from academia and pharmaceutical research companies.
