This Satelite Workshop is part of the annually scientific user meeting for DESY and XFEL. The workshop addresses current and potential users of small-angle X-ray scattering at PETRA III. It is intended to present and discuss the status and perspectives of the current and future experimental facilities in this field at DESY and recent as well as planned user activities. It shall foster communication among the users and identify common interests.

DAC at HED Instrument (programme)

Organiser: K. Appel, V. Cerantola, Z. Konôpkova, H. P. Liermann (DESY), St. McWilliams, C. Prescher, C. Strohm (DESY)

In recent years, performing experiments under dynamic high-pressure and high-temperature conditions in Diamond Anvil Cell (DAC) has become possible due to significant advances in DAC drivers, requiring highly brilliant x-ray sources with fast repetitions rates and short x-ray pluses to probe the extreme P-T states generated in these experiments. Ideally suited for such time-resolved x-ray studies is the HED instrument of the EuXFEL, which offers a dedicated x-ray diffraction platform in Interaction Chamber 2 (IC2) and a spectroscopy platform in Interaction Chamber 1 (IC1). After successful completion of the first community DAC experiment #2292, three additional DAC community proposals have been awarded beamtime in May 2021. In this workshop, we will report on the technical capabilities of the DAC platforms in IC1 and IC2 and give an update on the results from the first community DAC proposal #2292. Finally, we will discuss future developments of these platforms to perform more advanced dynamic high-pressure and high-temperature experiments in DAC at HED.

Industry Workshop (programme)

Organiser: S. Jaehmlich (ITT DESY)

From basic research to application: Beamtime at home with compact accelerators

As a national research lab, DESY strives to bring insights and results from basic research into application as fast as possible. This is why we look at our technological developments and breakthroughs as well from the aspect of knowledge and technology transfer.

One example is our Tech2Med proposal for the Clusters4Future initiative of the Ministry of Education and Research.

In this session you will find out about the vision behind Tech2Med:

  • Bringing a small, compact accelerator from the basic research stage to market maturity within a welldefined time frame.
  • Developing a compact accelerator with the potential to speed up insights and developments for drug developments and new medical imaging approaches
  • An Industry Advisory Board, which from the very beginning is the key to deliver a product, which reflects industry requirements
  • Standardizing cuttingedge analytical methods for the final product, such as applied serial crystallography (ASC) and Xray fluorescence imaging (XFI)

In addition, you will get first insights into Laser Plasma Acceleration (the heart of the compact X-ray source), as well as an overview on what DESY offers for industrial partners.

For questions, please contact Dr. Sabine Jähmlich (

Status and research high-lights of the ECB (P02.2) at PETRA III (programme)

Organiser: H. P. Liermann (DESY)

The Extreme Conditions Beamline (ECB) P02.2 at PETRA III is a micro to sub-micron X-ray diffraction beamline dedicated to high-pressure and simultaneous high/low temperatures research in the Diamond Anvil Cell (DAC). In 2020 the laser heating system at the ECB has under gone a significant upgrade in order to meet the ever-increasing needs of the community. Furthermore, we completed the upgrade of our sub-micron x-ray capabilities at 25.6 keV that are now increasingly requested by the user community. Within this satellite workshop we will present the current status of the ECB and present recent science highlights that make use of the new capabilities. Finally, we will give an outlook of the new developments planned for 2021 and future plans for the ECB at PETRA IV.


X-Ray Absorption Spectroscopy at P64/65 (programme)

Organiser: W. Caliebe (DESY), E. Welter (DESY)

The two XAFS-beamlines P64 and P65 are in user-operation mode now for several years. The satellite workshop is intended to give an overview about the current status of the beamlines, the associated projects, and results from different external user groups. Short- and long-term plans for instrumentation concerning experimental techniques and sample environments will be presented and discussed, as well as results from users' experiments.

New in this year will be first experience with mail-in experiments, which might become a normal mode of operation in future years. We will also report on the progress of the PETRA IV project and especially on the Scientific Instrument Proposals. Present and future users are strongly encouraged to participate in this workshop and to discuss their options with the beamline staff.

P 21.2 Beamline Users´ Meeting (programme)

Organisers: P. Hedström (CeXS) and U. Lienert (DESY)

High speed data and metadata handling for photon science experiments

Organiser: A. Barty (DESY)

This workshop focuses on challenges and solutions for the handling of high-speed data acquisition and processing at FLASH and PETRA-III, including the challenge of capturing and interpreting experiment metadata.  Data collection for complex experiments involves not only the recording of instrument data, but also the coordinated recording of associated metadata necessary for data interpretation.  As the demand for semi-automated and near-real-time data analysis grows, this metadata should be available in electronic form to guide the analysis chain.  At user facilities such as FLASH and PETRA-III, an important source of metadata are the users who not only provide samples but also determine the scientific goals of the experiment including the purpose of each data acquisition run.  Thus, strategies are required to ingest not only data from the instrumentation (detectors, motor positions, etc), but also information from the users coordinated with the instrument data in a synchronised manner and to make this available in the data analysis chain.  Here, we will explore available solutions with a view towards an integrated data handling solution for the operation of PETRA-IV.

In situ high-pressure studies using the Large Volume Press at P61B  

Organiser: R. Farla (DESY), S. Bhat (DESY)

Studies on mm-sized samples at high pressures and temperatures in the Large Volume Press using in situ X-ray techniques will soon be possible using a 2nd Ge-detector at beamline P61B. This enables structure determination from powder diffraction data at two different detector angles offering better resolution and a larger q-range. Rudimentary stress analysis with both detectors at 0° and 90° azimuthal positions at the same angle will also be possible. For the latter, assemblies using sintered diamond anvils are currently tested to allow in situ rock deformation studies using triple-stage setups. Because P61B only receives 50% beam time, we strive to serve users in other ways without X-rays. Hence, additional in situ techniques are being developed such as acoustic emissions testing, e.g. to study brittle processes in samples under stress, and ultrasonic wave speed measurements using a state-of-the-art oscilloscope and function generator. These set ups will also be available for beam time. At this dedicated meeting you will learn about the status, development and future of the beamline (e.g. at PETRA IV). We hope this meeting offers an opportunity for you to connect with the beamline staff and other users visiting (or planning to visit) the beamline, to foster new research ideas in all fields related with bulk materials at high pressure. We encourage you to submit a proposal for regular beam time by the deadline of 01 March 2021.
