Dear User,
We hereby announce the call for synchrotron beamtime applications in
biological small-angle X-ray scattering (SAXS), macromolecular
crystallography (MX) and X-ray imaging (XIMG) for the period *April –
August 2026*. Kindly note the PETRA III shutdown periods listed at the
end of the call text.
The following EMBL beamlines at PETRA III are available: P12 (SAXS,
TR-SAXS), P13 (MX) and P14 (MX including the T-REXX endstation and XIMG).
Submission of BAG (Block Allocation Group) proposals is encouraged.
*Groups applying for beamtime to work on several projects during 2026
are requested to submit their research proposals via a BAG application
and not as several individual proposals (even if the BAG only consists
of a single research group).*
Please note that, as of this call, it is mandatory for all user groups
that have used EMBL beamlines in the past, to submit a proposal as a
continuation of the previous one, as well as to complete and submit the
related proposal summary report.
For experiments intending to use the T-REXX endstation, please submit
your proposal (BAG or Single) under the T-REXX heading.
The deadline for submission of proposals for 2026 is:
*Monday, 27 October 2025 (midnight CET)*.
After this date, the proposals will be evaluated by an external Project
Evaluation Committee and the users will be informed about the results of
their application(s) in the second half of January 2026.
Support for access to the infrastructures is being offered via
Instruct-ERIC
<https://www.embl.org/about/info/hamburg-access-infrastructures/instruct-eric-funding/>,
please contact the User Office for details on how to apply.
A detailed description of the three beamlines and links to the
electronic proposal forms can be found on our Structural Biology
Services page <https://www.embl.org/services-facilities/hamburg/>. For
additional information and advice regarding submitting a proposal, visit
our Access to Infrastructures page
<https://www.embl.org/about/info/hamburg-access-infrastructures/>.
Please submit your proposal via the EMBL Hamburg user portal:
https://smis.embl-hamburg.de.
Access to the EMBL Hamburg facilities also includes assistance with
crystallisation, sample preparation and, in combination with an EMBL
beamline visit, with sample characterisation and optimisation.
