To apply for 2022 beamtime, submit a proposal via the EMBL user portal. The application deadline is Monday 18 October 2021 (midnight CET). Rapid access is available for COVID-19-related proposals and can be requested by contacting the user office.

P12 is an undulator beamline utilizing the wavelength range between 0.6 and 3 Å. The beamline is optimised for low background data collection from macromolecular solutions and kinetic experiments with high temporal resolution. The endstation is equipped with photon counting Pilatus and Eiger detectors, a robotic sample changer and in-line size-exclusion chromatography (SEC-SAXS) setups. P12 allows for fully automated and remote data acquisition and processing using the Beamline Meta Server software. Mail-in access is encouraged, both for sample changer and SEC-SAXS projects.

Access to the beamline P12 is available to all research groups, and is prioritised on scientific grounds only. Project proposals for beamline access are evaluated by the Project Evaluation Committee (PEC). For guidance on writing a project proposal for SAXS beam time, please consult these instructions.

How to reference P12

The use of the EMBL beamlines must be acknowledged in all publications or presentations arising from data collection at the EMBL Hamburg unit. The following note is expected to appear in the acknowledgements, giving reference to the station(s) used, supporting beamline staff or any other assistance or information, as appropriate, e.g. EU contract numbers, proposal numbers.

“The synchrotron SAXS data was collected at beamline P12 operated by EMBL Hamburg at the PETRA III storage ring (DESY, Hamburg, Germany). We would like to thank N.N.** for the assistance in using the beamline.”
