High-throughput Macromolecular Crystallography beamline P11, PETRA III, DESY

P11 is a 3rd generation synchrotron beamline for High-throughput Macromolecular Crystallography (MX). It is energy tunable in the range 5.5-26 keV and has adaptable optics for focused beam size varying from 200 µm to 5 µm, with a maximum flux of 1013 photons/second. The large capacity sample changer can hold 368 samples in Unipuck format. The state-of-the-art photon counting detector, Eiger2 X 16M, also contributes to the high throughput of the beamline, at which 720 samples can be measured per day, making it ideal for large scale campaigns. Experimental phasing is supported with fluorescence detector. The capabilities of the beamline allow serial crystallography which is realised using a tapedrive as sample delivery and facilitated by auto-processing routines. In classical MX, the beamline can be operated remotely, and unattended data collections are under development. The beamline is supported by a user laboratory that includes OLTShifter for semi-automated crystal harvesting.
