I will present recent advances in X-Ray Photon Correlation Spectroscopy (XPCS) at the MID instrument of the European XFEL. Access to sub-ms timescales is important for studying diffusion-type dynamics in aqueous solutions, for instance of colloids and bio-molecules. The European XFEL with its MHz repetition rate, provides this opportunity. XFEL experiments often require specialized sample...

In the past decades, X-ray ptychography has been demonstrated as a powerful technique of coherent diffractive imaging because of its capability to achieve quantitative phase contrast and nanoscale resolution not limited by the performance of X-ray lenses. It has seen applications in a broad range of research fields from microelectronics to biology [1,2]. However, because ptychography is a...

Oral

Soft X-ray coherent techniques have proved to be a powerful tool in the investigation of static and dynamic phenomena in solid-state quantum materials, such as ultrafast light-induced phase transitions [1], fluctuating domains [2] or memory effects [3]. One particular aspect of phase transitions is their possibility of being non-reversible and/or stochastic, which ties into mostly unexplored...

61. Unlocking the potential of ptychographic imaging with upgraded coherent sources

Oral

Recent breakthroughs in electron storage rings have enabled a notable increase in coherent X-ray flux, promising a potential acceleration in coherent imaging speed by several orders of magnitude. However, realizing this speed enhancement requires concurrent advancements in instrumentation and computation algorithms for X-ray ptychography. At the Advanced Photon Source, we have developed...

118. Next Generation Detectors for High-Resolution Experiments with High-Energy Coherent Synchrotron Radiation

Dr Max Burian (Dectris Ltd.)

Oral

High-resolution synchrotron experiments increasingly require advanced detection capabilities to address the challenges of high-energy coherent synchrotron radiation. Hybrid Photon Counting (HPC) X-ray detectors have emerged as pivotal tools in this context [1].The EIGER2 detector advances HPC technology with its 75 μm × 75 μm pixel size, kilohertz frame rates, negligible dead time (100 ns),...
