In order to exploit the complete scientific potential of high-energy XFELs (electron energy > 10 GeV), it is necessary to provide adequate pump sources to enable pump-probe science. The users of the European XFEL have requested a THz pump source matching the machine repetition rate (10 Hz burst mode with up to 2700 bunches per burst). [...]

At the Photo Injector Test facility at DESY in Zeuthen (PITZ), an R&D platform for electron FLASH cancer radiation therapy and r adiation biology isbeing prepared: FLASHlab@PITZ . The design of the full beamline with optimized beam properties was finished; the setup is currently beingfinalized and the mechanical design and manufacturing is underway. [...]

The ‘Young Crystallographers’ is a working group of the German Crystallographic Society (DGK) and was founded in 2013 [1]. Within the past 10 years, this working group became one of the most active groups within the society [...]

Extending the spectrum of attosecond pulses obtained via high-harmonic generation toward higher photon-energies is an important goal for attosecond spectroscopy.An extension of the cut-off photon energy of the high-harmonic spectrum is observed when the process is driven by non-sinusoidal waveforms with durations down to belowa single optical cycle. Specifically, while the phase-matched high-harmonic spectra generated in Neon by a "sinusoidal" pulse, with a wavelength of 1.6 μm and durationof 1.5 optical cycles, extends up to ~350 eV, the spectra driven by a non-sinusoidal pulse, with a central wavelength of 1.4 μm and duration down to 0.5 optical cycles,extends up to ~400 eV.This shows experimentally how non-sinusoidal sub-cycle waveforms violate the well known proportionality of the cut-off photon energy with the square of the central wavelength..

The development of novel laser sources has spurred the development of new characterization techniques. Here, we present a method to determine the complete optical waveform generated by a waveform synthesizer (WS) at the experimental interaction point up to one global sign of the electric field. [...]

We report on ongoing discussions and plans of NFDI consortia in physics and rel-tatednatural sciences with respect to (persistent) identifiers..

In particle physics, Monte Carlo (MC) event generators are needed to compare theory to the measured data. Many MC samples have to be generated to account for theoretical systematic uncertainties, at a significant computational cost. [...]
