Static Pressure Experiments at XFEL  (<-link to programme)

Organiser: H. P. Liermann (DESY), Z. Konopkova (European XFEL)
Location: DESY, FLASH Sem.R., Bldg. 28c

In October 2019 more than 70 scientist of the high pressure community from 7 nations collaborated in a community-assisted commissioning beamtime to develop a platform for high pressure experiments in the Diamond Anvil Cell at the High Energy Density (HED) Instrument of the European XFEL. The group benchmarked the capability of generating and probing extreme states using Diamond Anvil Cells, safely studying samples to pressures exceeding one 1 Mbar. During the beamtime the group commissioned and tested the DAC setup in the 2nd interaction chamber (IC2) of the HED instrument in conjunction with a VAREX flat panel detectors in order to collect time-integrated diffraction images from samples exposed to femtosecond X-ray pulses at MHz repetition rates, to experimentally explore some crucial aspects of XFEL DAC science such as e.g. diamond stability and X-ray heating using 17.8 keV XFEL. In this workshop we will discuss our findings as well as the plans for the near future for DAC work at HED in IC2.

Monday-Tuesday, 27-28 January  (Organised by European XFEL)

MID Workshop: First year of operation and future developments 

Organiser: Anders Madsen (European XFEL)
Location: European XFEL, XHQ E1.173, Schenefeld

The workshop is addressing the very first user experiments at the Materials Imaging and Dynamics (MID) instrument performed from March to November 2019. A status report of MID will be given together with selected presentations from user groups that span a diverse set of scientific topics, experimental techniques, and beam parameters. New equipment arriving at the instrument in 2020 will be discussed, e.g. a synchronized optical fs laser for pump-probe experiments and an X-ray split-delay line for XPCS applications. Together with developments of the source this will further broaden the scientific scope and strengthen the capabilities of MID.

First experiments with a high-intensity short-pulse laser at HED/HIBEF

This meeting will have a seperate registration.

Organiser: Toma Toncian, Motoaki Nakatsutsumi (European XFEL)
Location: European XFEL, XTOB 1.01, Schenefeld

The main goal of this workshop is to inform potential future users about the current development status of the high-intensity short-pulse laser commissioning at the HED instrument and discuss early user experiments. These include the High Intensity (~100 TW) laser (HIBEF/Amplitude) and the Pump-Probe laser (EuXFEL) systems. Summary and feedback to the previous 2017 workshop will be given. The workshop provides ample time for open discussion.

Satellite Meetings on Tuesday, 28 January (Organised by European XFEL)

User experience of data analysis at European XFEL

Organiser: Fabio Dall’Antonia, Hans Fanghor
: DESY, CSSB Lecture theatre (Bldg. 15)

This community driven satellite workshop is focused on sharing user experience from users with users. We anticipate three short sessions on the topics of (i) online data analysis, (ii) offline data analysis and (iii) data reduction. This is complemented with opportunities to network through informal exchanges.

Each session of about 30 minutes is planned to start with very brief presentation from users to kick start the discussions. The 3-slide presentation is to summarize the what, how and why of their specific data analysis at EuXFEL.

We invite all users to share their experience - be it through a 3-slide presentation or through participation in subsequent discussions. The remaining time is scheduled for questions and answers between presenters and audience. Future users are of course welcome to attend the event as well.

The emphasis of the event is on exchanging data analysis experience from using European XFEL to avoid duplication of effort, and for European XFEL to seek guidance on the community's wishlist for continued, improved and new services.

Chemical Dynamics Opportunities at the FXE Instrument

Organiser: Christian Bressler, Wojciech Gawelda, Dmitry Khakhulin
Location: DE
SY, CFEL SemR I-III, Bldg. 99
 and European XFEL, Schenefeld

The Femtosecond X-Ray Experiments (FXE) Instrument has recently taken large steps towards experiments for time-resolved x-ray emission (XES) and wide-angle scattering (WAXS) studies. The instrument can now host experiments, which demand an unprecedented high average flux and signal quality. This is possible due to the MHz delivery rate of 2-4 mJ x-ray pulses from the SASE1 undulator. Experiments at FXE will benefit from the spin and electronic sensitivity delivered from XES data, and from structural dynamics studies exploiting WAXS at up to 20 keV x-radiation. At these high energies one can more reliably determine the intramolecular structural changes, since the larger q values now available (to determine molecular structure changes) do not strongly depend on the much stronger solvent response, which is dominant in the low q range previously covered by <10 keV WAXS studies.

The FXE User Workshop will focus on the current operation status and present recent user experiments. It is ideally addressing scientists who are considering to exploit FXE for their research. The meeting also aims at opening up opportunities for discussion and setting up collaborations, especially for new or unexperienced users.

Scientists wishing to acquire a general knowledge about our instruments, the present status of the facility and the unique capabilities of the instruments in steady operation, are encouraged to also attend our Users’ Meeting right afterwards (29-31 January 2020) in Hamburg, which will also allow discussion with our scientists and obtaining useful information for future beam time proposals.

Current status and future completion at the HED instrument and the HIBEF contributions

Organiser: Ulf Zastrau, Carsten Baehtz
Location: European XFEL, XHQ E1.173, Schenefeld

The half-day workshop on the HED instrument and the HIBEF User Consortium will take place in the large seminar room E1.173 at the European XFEL headquarter building in Schenefeld. You will hear status updates of different experimental setups, which came online in the last month, and perspectives of the HED instrumentation also in view of beamtime application for upcoming runs. After a coffee break, the second part of the afternoon will concentrate on HiBEF UC contributions with special emphasis on the High-Energy laser DIPOLE, which will be installed and commissioned in 2020, and diagnostic tools used in shock compression experiments. In addition, status of the TW laser and planned first commission experiments will be represented. We plan for a reception in the “BeamStop” Restaurant in the evening.

High-pressure Science in the Large Volume Press at Beamline P61B

Organiser: Robert Farla, Shrikant Bhat
Location: DESY, SemR 456, Bldg. 25f

Studies on mm-sized samples at high pressures (and temperatures) in the Large Volume Press using in situ X-ray techniques are now possible at beamline P61B. In the first half of 2020, commissioning continues with 1 Ge-SSD and a double-objective X-ray microscope for energy-dispersive X-ray diffraction in the energy range of 30 – 200 keV with an unprecedented amount of photon flux. Efforts to eliminate characteristic Pb emissions (from shielding) and to reduce the background in the diffraction patterns from scattered X-rays are promising. Dedicated radiography (imaging) experiments in the LVP can be carried out using a 2 mm x 2 mm beam. A precise detector positioning system (built by Kohzu) will be delivered and installed in the period of April – May 2020. Following this, a second Ge-SSD will be added to the detection set up. The LVP is fully adapted for many different anvil/assembly set ups and can operate in 3 modes of compression, particularly to enhance the opportunity to conduct in situ rock deformation studies. During this dedicated satellite meeting for the LVP beamline P61B, beamline status, ongoing research and collaborative efforts will be presented. The meeting offers an opportunity for current and new users to meet with the beamline staff and with each other to discuss new research ideas for high pressure studies in the fields of Earth and Materials sciences and organic/inorganic Chemistry. P61B is joining the current call for proposals for beam time starting in August 2020.

Central infrastructure for DESY Photon Science Scientific computing - update and future directions

Organiser: Anton Barty, Martin Gasthuber, Andre Rothkirch
: DESY, SemR BAH1/BAH2, Bldg. 3

An increasingly tight collaboration between physicists, scientific computing and IT experts is required to manage the ever growing data rates and data volumes from high speed detectors.  Modern detectors can generate multiple tens of TB data per hour.  Measured data has to be  collected from a diverse range of instrumentation, monitored in real time, assembled with instrument parameters and data from multiple detectors operating at different acquisition rates, transferred to a data center, analysed, archived, and exported to the user. The range of the challenges is quite broad:  most experiments can benefit from online data analysis (synchronous to experiment), some experiments require clearly defined workflow automatisation/containerisation going in direction of "experiment as a service”, while others require interactive data analysis e.g. via Jupyter Notebooks.

This satellite workshop addresses the increasing demand for cooperation between central IT and DESY photon science in the field of scientific computing.  It will give an update on work done in the previous years, solutions and practices at DESY today, and future plans and directions to address coming challenges including the coming needs of Petra-IV

Topics to be discussed include, but not limited to:

- Compute infrastructure (Maxwell cluster, new network from beamline to/from DC, ...)

- IT analysis services (Jupyter, Container, ...) - embedding your analysis code

- Data transfer (HiDRA) - Detector to DC and more

- The challenge of ingesting and synchronising high speed data from heterogeneous instrumentation

- Pilot projects and testing (ASAP:O, FaaS, Archiver)

- Remote access for analysis: user access to data and computing both on and off site; account and access management

- Future directions for data storage and data analysis (online & offline) - proposals/options/constrains

- Data policy, open science, and FAIR data

- What do users and beamline scientists want?

The workshop organizers (IT/FS/CFEL) is aiming for a more interactive arrangement and would like to include, as much as possible, your topics/questions/comments around the workshop context.

The Workshop is a great venue to share any items on your (computing/storage/network/...) wish list, to ask technical questions, and to have a discussion with fellow participants. Please submit your discussion item(s) using this Web form before you come to DESY attending the workshop:  https://forms.gle/1WiFwYCWaBs1HWUT6

Knowing the issues in advance will help the organizers to be better prepared. We look forward to seeing you at the round table discussion.
