Two low carbon (0.22 wt.%) carbide-free bainite (CFB) alloys were prepared by isothermal transformation at three differenttransformation temperatures. The distribution of carbon in bainitic ferrite (BF), retained austenite (RA) and martensite (M)phases was studied using a combination of in-situ high energy X-ray diffraction (HEXRD), atom probe tomography (APT) andelectron energy loss spectroscopy (EELS).

In the contemporary context of research, financial expenditures are escalating at an alarmingrate.This encompasses not only direct expenses associated with the research process, such asstaff, hardware, and equipment, but also the dissemination and archiving of results. Usually,these costs remain inaccessible to the public, a state of affairs that is deemed to be highlyunsatisfactory. [...]

Over the past year a new beamline dedicated to R&D for electron FLASH cancer radiation therapy and radiation biology was set up at the Photo Injector Test facility at DESY in Zeuthen (PITZ). The beamline runs in parallel to the SASE THz beamline at PITZ and is connected to it with an achromatic dogleg. [...]

To detect faint signals from weakly scattering samples, high-resolution x-ray microscopy typically requires a high photon flux. This exposes samples to high radiation doses and can cause radiation damage. [...]

Scanning an X-ray nanobeam instead of the sample can be highly advantageous in experimental scenarios where a fast sample movement is not possible, such as in-situ measurements. Here, fast sample scanning is often hampered by a heavy or bulky sample environment. [...]

The parton branching method is crucial for Monte Carlo generators, which are essential for high-energy physics predictions. We examine the impact of soft gluons on inclusive collinear and Transverse Momentum Dependent (TMD) parton densities. [...]

Nanofocusing with refractive x-ray optics requires the combination of many single lenses into a larger lens stack to achieve high numerical apertures. So far, these optics have suffered from aberration due to accuracy limitations in x-ray lens manufacturing [...]

Differentiable beam dynamics simulations are in demand, e.g., to solve inverse and optimization problems in accelerator and beam physics. Here, the two modern open source codes Cheetah and ImpactX are compared in their approach to performance-portable programming and automatic differentiation. [...]

The European X-ray Free Electron Laser (EuXFEL) began its user operation five years ago, opening and offering new research possibilities. The facility delivers high brilliance, ultra-short, spatially coherent x-ray pulses with a high repetition rate to six instruments (FXE, SPB/SFX, MID, HED, SCS and SQS) by means of three different beamlines (SASE 1, SASE 2 and SASE 3).
