PETRA III beamlines (without P12-P14)

regular proposals

The call for regular proposals for experiments at PETRA III is currently open.
The deadline for proposal submission is Friday 1 March 2019 (inclusive).

This call relates to the second run period in 2019 (July to December 2019).
Proposals for PETRA III can be submitted for beamlines P01 to P11, P21 to P24, P64 and P65.
The rheometer setup at P10 is not available for user experiments.
Beamline P21 went into operation only recently and users are strongly requested to discuss technical requirements with the beamline staff prior to proposal submission.

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

We would like to inform you that the Powder Diffraction and Total Scattering Beamline, P02.1, will be offering a rapid access trial run in June 2019. This access route allows users to send capillary mounted polycrystalline samples to DESY for measurement by beamline staff.
The aim of this first run is to understand demand from the community for this access route and to develop sample and data handling methods for a possible future expansion of this program. As this is a trial run, we are offering powder diffraction (PXRD) and Pair Distribution Function (PDF) measurements under ambient conditions only. This call will be limited to 10 samples per group.
Data collection will be performed remotely by beamline staff, meaning that only your samples need to be sent to DESY. To submit a proposal, please send a half page abstract detailing the science case, as well as details of the number of samples and type of measurements needed (PDF and/or PXRD) to by 17:00 on Monday 8th April 2019. We aim to inform successful applicants by early May and capillary loaded samples should arrive at DESY no later than 1st June 2019. Data should be available by the end of June 2019.
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.

BAG proposals and LTP

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 open from 17 December 2018 until 15 January 2019.
Available beamlines will be announced as soon as possible.


The call for proposals for experiments at FLASH at DESY is open.
Deadline for proposal submission is Monday 1 April 2019 (inclusive).
This call relates to the run period January to July 2020.
