Within FS-EC (Experiment Control) we develop and adopt software solutions that cater the data acquisition processes in user operation in FS facilities as well as fundamental background services that are needed for a performant beamline infrastructure. The group covers aspects spanning across high level controls (Sardana), low level controls and hardware abstraction (Tango), detector drivers...
Applying for measurements at large X-ray sources like PETRA III at DESY or BESSY II at HZB is highly competitive. If granted beam time, numerous samples need to be measured. These measurements often occur under in-situ or operando conditions, such as studying the degradation of a biodegradable Mg wire or structural changes in a battery during charging. These changes happen at a sub-micron...
I present an overview over the simulation activities done with the XRAYPAC tookit developed at FS-CFEL-3.
Overview of RIC activities for FS, including e.g. results from EU projects and collaborations with LEAPS and Helmholtz.
A short overview of the services provided by central IT specifically for FS data taking and data processing, especially the ASAP3 framework and related services.
Accurate and precise information about the position of the detector is critical to the success of many types of experiment in photon science. This is particularly true for serial crystallography, which is sensitive to detector misalignments of less than one pixel’s width. However, serial crystallography data is also very useful for refining the detector geometry, consisting of sharp, bright...
This presentation offers a succinct examination of FLASH, emphasizing the facility's key features. It outlines the IT infrastructure and collaborative relationships with different DESY groups. Additionally, it delves into the technical aspects of experimental control, data acquisition, and analysis methods. The talk also sheds light on current projects and future directions.
New detectors produce increasing volumes of data, and so performing data reduction close to the detector (e.g. on detector-specific data acquisition PCs) can potentially reduce the workload on later infrastructure. I will present on current work on this in FS-DS. Also, for historical reasons, FS-DS are responsible for the DESY part of a few collaboration projects on data reduction: Data-X,...
We'll give an overview of our computational projects at beamline P11.
We will present the work and expertise of the newly established Computational Imaging Group at DESY. Being founded in mathematics, we provide expertise in inverse problems as well as theoretical foundations of machine learning methods.
We give an overview of mathematical methods in imaging and applications thereof, in particular algorithms for reducing computational cost in large scale...
Can laser-induced molecular wave packets be used as a quantum simulator?
Current femtosecond crystallography data processing routines such as CrystFEL by T. White generally assume that identical molecular structure for each of the tens of thousands of protein crystals used. This assumption is however known to be unphysical, and with the recent development of deep learning technology, we are exploring whether we can build a net capable of shaking out the subtle...
Within this contribution, an overview of the imaging program of the SAXSMAT beamline P62 will be given. Especially, the computational aspects of the 3D reconstruction for the SAXS- and WAXS tensor tomography imaging experiments will be presented. Furthermore, an outlook of upcoming projects that include AI in the reconstruction algorithms will be discussed.
Besides the 3D tomography datasets...
