Status and research highlights of the ECB (P02.2) at PETRA III
Organizer: H. P. Liermann

Time: 13.30 -17.30  PDF  programme

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 2021 we continued the upgrade of laser heating system at the ECB in order to meet the ever-increasing needs of the community. Furthermore, we implemented Partially-Coherent Propagation-Based Phase Contrast Imaging in the dynamic driven DAC. Within this satellite workshop we will present the current status of the ECB and recent science highlights that make use of the new capabilities. Finally, we will give an outlook of new developments planned for 2022 and the plans for ExTReM at PETRA IV.

X-ray Absorption Spectroscopy and X-ray Diffraction Satellite Meeting
Organizer: A. Schoekel, W. Caliebe

Time: 13.00 - 18.00  PDF Programme

Multimodal measurement techniques are of ever-increasing demand to tackle many pressing questions in a multitude of research fields. Especially the combination of complementary techniques in one single experiment offers many advantages, since it makes results directly comparable. So far, most experiments, which required information from X-ray Absorption Spectroscopy (XAS) and from X-ray Diffraction (XRD) measurements were performed at two different instruments. Just a few combined experiments have been performed at DESY in recent years. This satellite meeting will give an overview on how results from XAS and XRD measurements are combined in current research at DESY, and what the future developments at PETRA III and PETRA IV for 
combined experiments could look like.

We are looking forward to some highlights from user research and an outlook to future possibilities at DESY. Please contact Wolfgang Caliebe ( or Alexander Schökel ( for further details.

Science driven data management solutions
Organizer: A. Barty

Time: 13.00 - 17.00

The data volumes and data rates generated by state-of-the-art high frame rate multi-megapixel detectors demand new approaches to how users manage their experimental data.  There is a desperate need for user-oriented tools to help users manage their large datasets, from data collection through to analysis, publication and long-term archiving.  Meanwhile, the trend to request data associated with publications be made openly available and repeatable the development of user-focused tools to facilitate and simplify this process.   This satellite engages with users to determine the data management tools needed to improve their research data management workflows.  It forms a part of the Daphne4NFDI project, an initiative funded as a part of the German NFDI program to develop infrastructures to serve the future data management needs of the photon and neutron science community.

The Swedish Materials Science beamline at PETRA III

Time: 13:00 - 17:30

Organizer: U. Lienert   PDF programme

This satellite meeting focusses on the in-line branch P21.2 of the Swedish Materials Science beamline at PETRA III which is dedicated to multi-modal materials characterization by high-energy synchrotron radiation. The status of the beamline will be presented and future developments will be discussed. Selected experimental case studies will be presented by users. A summary of activities at the P21.1 side-station will also be given. An activity report of the Center for X-rays in Swedish Materials Science (CeXS), the academic host of the SMS beamline, will be presented.

Tuesday 25th January 2022

Organizers: Stephan Roth; S. Haas, F. Bertram

Time: 09.00 - 18.00  PDF programme

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.

In situ studies at extreme conditions using the Large Volume Press at P61B
Organizers: R. Farla, S. Bhat

Time: 13.00 - 18.00  PDF programme

In situ studies on mm-sized samples at high pressures (< 30 GPa) and temperatures (< 2300 K) in the Aster-15 LVP are now routinely possible at P61B using the white X-ray beam, 2 Ge-detectors and the X-ray microscope. Energy-dispersive X-ray diffraction can be combined with press rotation of the sample in the beam, particularly useful when the sample develops large grains (at high T) or a crystallographic preferred orientation (due to deviatoric stresses). One of the two detectors can be tilted vertically to collect diffracted X-rays between the WC anvils in cubic compression mode. This setup can be enhanced using both detectors and X-ray transparent sintered-diamond anvils for in situ studies of rock deformation at high pressures (4 – 15 GPa). Imaging experiments, such as falling sphere viscosimetry, are possible. Furthermore, we offer additional in situ techniques, such as 1) acoustic emissions detection to study brittle processes in samples under stress, and 2) ultrasonic wave speed measurements to study the elastic/seismic properties of materials under range of conditions of P & T. Both systems are available for beam time and experiment time with and without X-rays, respectively. For resistive heating, we offer the choice of using a DC or AC heating system. More details on the status, development and future of the beamline (also at PETRA IV), will be presented at this dedicated workshop. We hope this meeting offers an opportunity for you to connect with the beamline scientists and invited speakers, and we encourage you to submit a proposal for regular beam time by the deadline of 01 March 2022.

Accelerating the industrialization of metal 3D printing
Organizer: Nadja Kölpin, ITT/DESY

Time: 13.00 - 15.00

The industrialization of 3D printing offers the opportunity to simplify and accelerate production and development processes. The technology provides the chance to completely rethink products in terms of designs and functionality. For metal processing additive manufacturing is opening up new dimensions: It enables filigree shapes for complex components that would not be possible using conventional manufacturing processes. At the same time, mastering the materials is challenging and prone to risk. 
How can we make 3D printing technology ready for serial production? What methods for quality assurance need to be developed? How can x-ray-analyses help to identify defects at an early stage? What processes on the nanoscale influence the outcome of printing processes? How can DESY contribute with its equipment in the area of process optimization, analysis and standardization? And how can the research facilities of tomorrow like PETRA IV boost these findings? This seminar aims to give new impulses on the current chances and challenges of metal 3D printing and will share insights from scientists and industry experts.

Studying molecular water
Organizer: Chris Milne

Time: 9:00 - 16:30 PDF Programme

Water is fundamental to life on Earth, which has long made it an intense area of research across many disciplines, and yet many of its physical properties are still not well understood. With the ultrashort, intense, and spatially coherent X-ray pulses available at X-ray free electron lasers there is the potential for rapid advances in our understanding of molecular water. In order to support and encourage this important area of research the European XFEL will issue a special Call for Proposals focussed on molecular water research and this satellite meeting will introduce and define the initial Expression of Interest phase of this call.

The aim is to allocate ample time for discussions and interactions between potential new user groups, experienced users, and the MID staff scientists.


The SXP instrument at the European XFEL: status and perspectives
Organizer: M. Izquierdo

Time: 09:00 – 14:00 PDF Programme

The SXP (Soft X-ray Port) is the third instrument at the soft X-ray undulator system of the European XFEL. The core idea of the instrument is to extend the portfolio of techniques available at the baseline instruments SCS and SQS. In this workshop, the status of the project and its new scientific perspectives will be discussed.

Currently available instrumentation will be presented along with few selected results of user experiments. The aim of this workshop is also to introduce our plans for instrument upgrades. A final roundtable session will provide the user community ample time to discuss with instrument scientists present capabilities and future directions offered by the SCS Instrument.


Detectors at European XFEL
Organizer: Monica Turcato

Time: 14:00 - 16:30 PDF Programme

The European XFEL specific time structure poses challenges to the development of detectors, which are able to cope with it. These challenges, the burst mode in particular, are at the moment unique to the EuXFEL facility. The detectors for the European XFEL have on one hand to satisfy stringent requirements similar to those of detectors used at other facilities, like the low noise and the high dynamic range, and in addition, be able to collect frames at a maximum frame rate of 4.5 MHz, in a burst lasting maximum 0.6 ms. Detectors with these features did not exist when the European XFEL was founded and do not exist now, with the exception of those in use at the EuXFEL. The large MHz detectors, the AGIPD, DSSC and LPD, have been developed specifically for the European XFEL and are the results of a development effort that lasted many years.<

After four years of operation, relevant progress has been made on the understanding of the MHz detectors, resulting in significant improvements in the quality of the produced data. In addition to the MHz detectors, other detectors running at a lower frame rate have been installed at the instruments, allowing the investigation of other scientific cases. Among those, especially the Jungfrau is widely used and is providing good scientific data.

The workshop aims to illustrate which detectors are in use at the different beamlines, their specifications, how they are operated, the achieved performances and the scientific cases for which they are used.  The input of the users is highly welcome, especially in illustrating how a specific detector feature is improving the scientific data quality, or if it now constitutes a limitation for science, as this will help address future detector developments for the next generation of detectors to be used at the European XFEL.

Data analysis at the European XFEL (introduction to data analysis, including machine learning)
Organizer: Luca Gelisio

Time: 09:45 - 18:30 PDF Programme

The experiments performed at the European XFEL generate enormous amounts of data.

While online analysis, which happens in near real-time, provides crucial feedback to steer the experiment, more rigorous offline analysis is necessary for new scientific findings

One of the missions of the Data Analysis group is to provide tools to enable analysis and interpretation of data, both online and offline.

We will also talk about how artificial intelligence and machine learning can be used for data analysis, and discuss new ideas together.


Lighting up Mass Spectrometry – Structural investigations of biological systems
Organizer: K. Lorenzen

Time: 09:00 - 18:00 PDF Programme

When thinking of Mass Spectrometry, the first picture that comes to mind is analysis of isotopes, small molecules and proteomics. However, Mass Spectrometry has entered the field of structural analysis of proteins and protein complexes already well over thirty years ago when John Fenn discovered electrospray ionization is applicable to large molecules. From then on, the field developed a range of comprehensive methods and instrumentation expanding the field of structural biochemistry. Additionally, lasers and light sources in recent years have improved in intensity allowing to probe low density targets of single molecules such as gas phase ions. In this workshop, current possibilities on merging the two fields are to be discussed, exciting new research and future developments addressed.

To understand a chemical or biological process, insight into structure and movement is crucial. We would like to draw attention to mass spectrometric methods, especially in combination with photons, be it scattering, fragmentation or spectroscopy, as well as the new field of mass photometry. Light can provide additional insights into structure beyond mass and ion mobility, i.e. gross shape, as the interaction depends on subtle changes in structural arrangements. Future applications are manifold and cover all molecules relevant to life, including the four main classes proteins, nucleic acids, glycans and lipids. Therefore, this is of general interest, way beyond analytical aspects, facilitating to understand
biochemical processes.

The workshop is organized by the MS SPIDOC consortium (Horizon 2020 grant No 801406) inviting international experts. The workshop will give a comprehensive overview of the field of structural mass spectrometry coupled to different light sources from an experimental and theoretical perspective.
Current important research and instrument developments as well as future ideas and applications will be highlighted.
