PETRA III beamlines (without EMBL P12-P14)

regular proposals

The call for regular proposals for PETRA III is published twice a year. The deadline is typically on 1 March and 1 September.
At present proposal submission is closed. Registered DOOR users will be informed by e-mail about the call opening.

LTP and BAG proposals

The call for proposals for Long-Term Projects (LTP) and Block Allocation Group (BAG) at PETRA III beamlines is currently closed.
The next call for LTP and BAG will be opened in December 2019.

NEW: Rapid Access at P02.1 at PETRA III (Powder Diffraction and Total Scattering Beamline)

The Powder Diffraction and Total Scattering Beamline, P02.1, will be offering a rapid access in near future. This planned access route will allow users to send capillary mounted polycrystalline samples to DESY for measurement by beamline staff.

As soon as the submission procedure for rapid access proposals is implemented we will inform all users via DOOR.

Proposals will be reviewed on their scientific merit, technical feasibility and also on genuine need of rapid access (e.g. a measurement needed to complete a paper or a scientifically interesting study, which requires less than 2 shifts of normal beamtime).

If you have any technical questions relating to a rapid access proposal, please contact or other P02.1 beamline staff.
