Satellite Meetings on Tuesday, 22 January (Organised by European XFEL)

Biological Sample Preparation and Characterisation for XFEL Experiments"

Organiser: K. Lorenzen
Location: European XFEL, XTOB 1.01, Schenefeld


XFELs open up new possibilities for life science experiments from imaging of single molecules to monitoring of biochemical reactions. The science critically depends on the performance of the X-ray laser and on quality of samples that are placed into the X-ray beam. Many biological transformations happen on time scales shorter than some minutes, and an optimal use of the beam heavily depends on well prepared and thoroughly characterised samples. This workshop will focus on sample preparation, characterization, sample environment for biological samples at the SPB/SFX end station, results of first experiments at the European XFEL as well as novel developments in these areas.

Early science at the HED instrument and status of the HIBEF contributions

Organiser: : U. Zastrau and C. Baehtz
Location: European XFEL, XHQ E1.173, Schenefeld


The half-day workshop on the HED instrument and the HIBEF UC will take place in the large seminar room E1.173 at the European XFEL headquarter building in Schenefeld. In the morning, smaller meetings and tours of the experimental hall and the HED instrument are possible upon request to interested colleagues. After lunch in the foyer of EuXFEL, you will hear status updates and perspectives of the HED instrument, in preparation for the next call for proposals in late spring 2019. After a coffee break, the second part of the afternoon will concentrate on HiBEF UC contributions with special emphasis on the TW laser which will become available to users in 2020. We plan for a reception in the foyer in the evening.

Tuesday, 22 January (Organised by DESY)


Organiser: R.Treusch
Location: DESY, Bldg. 28c, FLASH Sem.R.


Within the DESY strategy process for the next decade – DESY2030 – long-term upgrade goals for the future of FLASH have been defined which are strongly based on user demands for a high repetition rate XUV and soft x-ray FEL facility formulated at the FLASH user workshop in September 2017.

This full day satellite workshop is a follow-up to the latter since we are in process of writing a conceptual design report for FLASH2020+ and would like to further discuss facility concepts and performance goals with you. In addition to this discussion of overall strategy and concepts, we will have two dedicated topical sessions, one on present and future data acquisition and controls and one regarding flexible (pump-probe) laser schemes, the latter continuing the fruitful discussion of last year’s satellite workshop.

We have foreseen time slots for short contributed oral presentations and would strongly encourage all span style="color:#696969">present and future users to participate in shaping the future of FLASH.

This workshop brings together experienced users, interested researchers, and beamline staff to present and discuss the current and future high-energy X-ray diffraction capabilities at DESY and key experiments that demonstrate the potential of this technique.

Extreme Conditions Research at the PETRA III

Organiser: H.-P. Liermann, R. Farla
Location: DESY, Bldg. 25f, Sem.R. 456


Extreme Conditions Research at high pressures and simultaneously high/low temperatures will be significantly strengthened at DESY in 2019 through the commissioning of the LVP beamline at PETRA III. Planetary and materials research can be performed under a wide range of conditions on small samples at very extreme pressures at the ECB (P02.2), and on larger samples at moderate pressures (< 25 GPa) at the LVP beamline (P61B). At the ECB we have refined dDAC operation as well as imaging within. Super high-pressure experiments are now benefitting from sub-micron diffraction experiments. At P61B, high energy polychromatic X-rays (30-200 keV) are expected to be available by late spring of 2019, followed by commissioning of the beamline for in situ energy-dispersive X-ray diffraction and imaging (e.g. radiography) experiments in the LVP. During this satellite meeting we will present ongoing research from different external and internal groups at the different high-pressure beamlines of PETRA III and give a status report on the current status of the Extreme Conditions CDR for PETRA

Especially for aerospace, automotive, railway or other civic industries, faultlessness in terms of reliability and safety of the engineering components is a must. With the introduction of new ways of fabricating components such as additive manufacturing or the development of new designs to reduce energy consumption, the complete understanding of these components, which are often operating under extreme conditions, not negotiable. What are the best ways to achieve this understanding? This seminar aims to give you the answer. We will showcase how synchrotron radiation and neutrons can, in a non-destructive manner, give insights into the behavior of materials and engineering components during fabrication or operation. Several techniques will be explained and linked to current questions.
