X-ray absorption spectroscopy at PETRA III beamlines P64 and 65    programme (& venue)
Organiser: Edmund Welter, Wolfgang Caliebe  

Beamline P65 went into full user operation in June 2016, and P64 finally got first beam in May 2016. The satellite workshop is intended to give an overview about the current status of both beamlines P64 and P65, and the associated projects. Short- and long-term plans for instrumentation concerning experimental techniques and sample environments will be presented and discussed. Present and future users are strongly encouraged to participate in this workshop and to discuss their options with the beamline staff.

7th Workshop on X-Ray Nano-Imaging of Biological and Chemical Systems at PETRA III  programme (& venue)
Organiser: Christian Schroer, Gerald Falkenberg

The workshop covers X-ray microscopy at PETRA III with special emphasis on applications in biology and chemistry. It is held for the 7th time and brings together scientists from biology, chemistry, and x-ray microscopy. This satellite workshop covers some recent methodological and instrumental developments at PETRA III and the Nanolab as well as some scientific applications. X-ray microscopy will greatly benefit from a future upgrade of PETRA into the ultra-low emittance source PETRA IV. Participants are encouraged to discuss future scientific opportunities.

Organization Instrument Workshop - New instrument for ultrafast spectroscopy of small quantum objects at FLASH I and II    programme (& venue)
Organiser: Stefan Düsterer, Markus Guehr

The new URSA-PQ instrument at FLASH has received funding and is planned to enter commissioning phase in 2019. The instrument is designed for pump-probe spectroscopy of diluted samples in the gas phase. Pump and/or probe pulses are optical laser and x-ray laser pulses from FLASH. The instrument is held compact and modular and can be flanged onto different beamlines at FLASH 1 and FLASH 2. We will have a magnetic bottle time of flight spectrometer available capable for taking electron as well as ion spectra. A sample delivery system for powder molecular samples as well as a gasphase effusive beam is included in the project. We want to address a maximal number of users with that instrument and thus keep it as flexible as possible under the baseline funding. We invite the user community to express their scientific ideas and specify instrument extensions, if needed. Every participant is invited to present a 5-10 min overview of his/her ideas for the instrument. Please contact Markus Gühr (mguehr@uni-potsdam.de) for further questions.  

Extreme Condition Science at DESY  programme (&venue)
Organiser:Hanns-Peter Liermann

Extreme Conditions Research at high pressure and simultaneous high and low temperatures continues to grow at DESY. Planetary and materials research at low and moderate temperatures can be performed at the ECB (P02.2) and in future at the LVP beamline (P61.1) while research in the WDM regime can be performed at FLASH. However, Extreme Conditions Research is also performed more frequently at other beamline of PETRA III. New possibilities for research at both cold compressed and WDM will emerge from DESYs contribution to the HIBEF project located at the HED Instrument of the European XFEL. Furthermore, we are starting to think about the possibilities that a diffraction limited storage ring such as proposed for PETER IV might offer in the not so far future. Within this satellite meeting we will present ongoing research from different user groups at the different beamline of PETRA III and FLASH, give a status report on the DAC platform at the European XFEL and give an outlook on first scientific ideas that make PETRA IV unique among other small emittance 3rd generation light sources.


Light-Matter Interaction: Recent Advances in Theory    programme (&venue)
Organiser: Beata Ziaja-Motyka (Executive), Sang-Kil Son, and Robin Santra

It is intended to present and discuss the status and perspectives of the experimental facilities, especially the PETRA III micro- and nanofocus X-ray scattering beamline P03 (MiNaXS), and recent as well as planned user activities. It shall foster communication among the users and identify common interests.

Serial Crystallography at FEL’s and synchrotrons   programme (& venue)
Organiser: A. Mancuso, A. Meents, J. Schulz, H. Chapman

Serial Femtosecond X-ray crystallography (SFX) at X-ray Free Electron Lasers (XFELs) has changed the way crystallographic data can be collected. Instead of investigating one or a few large crystals, still images from hundreds to hundred of thousands of crystals are collected in series. Recently, the technique of serial crystallography has also been very successfully applied at synchrotron sources. In addition to determinations of ground state structures from micro- and nano-crystals, an important potential of serial crystallography is studying kinetics of irreversible enzyme reactions. Dynamic events can be induced in different ways; such as laser excitation, microfluidic mixing, temperature jumps, cleavage of caged compounds, and others.
With the European XFEL and the PETRA III storage ring the Hamburg area offers excellent opportunities for serial crystallography experiments. During this workshop, application experts will present their latest results along with facility experts showcasing the experimental opportunities at the SPB/SFX instrument of the European XFEL and the PETRA III biology beamlines.


'Holographic Imaging and Tomography' -Tutorial   programme (& venue)
Organiser: Michael Sprung, Felix Beckmann, Imke Greving

New (coherent) X-ray imaging capabilities have been developed, implemented and exploited at several instruments of PETRA III, e.g. at the beamline P05 (HZG) and the P10-GINIX setup (build by the University of Göttingen).  Some of the interesting options include high resolution near-field imaging in the holographic regime and tomography using micro-focused X-ray beams.  These developments led to the highest resolution images recorded in full-field in-line holography (Bartels et al., PRL 114, 048103) as well as to novel opportunities for tomographic imaging of biological cells and tissues (Krenkel et al., Scientific Reports 5, 9973, 2015). The full field micro tomography setup offers high-throughput user experiments in absorption mode and opens up unique possibilities in phase contrast mode (Scientific Reports 6, 2016). In addition the nanotomography experiment is now in user operation offering full field x-ray microscopy at high spatial resolution (Ogurreck et al., JSR 23, 2016).
The first part of this tutorial workshop will give an introduction to both techniques and present the current instrumentation available at P05 and P10. Afterwards presentations will demonstrate the current capabilities and limitations of both instruments.


High resolution diffraction at solid and liquid interfaces   programme  (& venue)
Organiser: Florian Bertram & Bridget Murphy

This workshop will address current and potential users working in the field of diffraction and scattering on surface, interface, and thin film structures.

The high resolution diffraction at solid and liquid interfaces workshop will focus on recent and future activities at the P08 High Resolution Diffraction Beamline using the high resolution Kohzu diffractometer and the Liquid Scattering Apparatus (LISA). In the workshop we would like to bring the user communities of both instruments together to discuss current and future possibilities at P08 and to enhance communication within the user community.
