A new benchmark of soft X-ray transition energies of $\mathrm {Ne}$, $\mathrm {CO}_2$, and $\mathrm {SF}_6$: paving a pathway towards ppm accuracy
/ Stierhof, J. (Erlangen - Nuremberg U.) ; Kühn, S. (Heidelberg, Max Planck Inst.) ; Winter, M. (Erlangen - Nuremberg U. ; Neel Lab, Grenoble) ; Micke, P. (CERN) ; Steinbrügge, R. (DESY) ; Shah, C. (NASA, Goddard ; Heidelberg, Max Planck Inst. ; LLNL, Livermore) ; Hell, N. (LLNL, Livermore) ; Bissinger, M. (Erlangen - Nuremberg U.) ; Hirsch, M. (Erlangen - Nuremberg U.) ; Ballhausen, R. (Erlangen - Nuremberg U.) et al.
A key requirement for the correct interpretation of high-resolution X-ray spectra is that transition energies are known with high accuracy and precision. We investigate the K-shell features of Ne, CO$_2$, and SF$_6$ gases, by measuring their photo ion-yield spectra at the BESSY II synchrotron facility simultaneously with the 1s-np fluorescence emission of He-like ions produced in the Polar-X EBIT.

U.) ; Hupe, Oliver (New Brunswick U. ; Braunschweig Tech. U.) et al.
First investigations regarding dosimetric properties of the hybrid, pixelated, photon-counting Dosepix detector in the direct beam of a pulsed photon field (RQR8) for the personal dose equivalent $H\mathrm{_p(10)}$ are presented. The influence quantities such as pulse duration and dose rate were varied, and their responses were compared to the legal limits provided in PTB-A 23.2. [...]

(Naples U.) et al.
The exploration of the universe has recently entered a new era thanks to the multi-messenger paradigm, characterized by a continuous increase in the quantity and quality of experimental data that is obtained by the detection of the various cosmic messengers (photons, neutrinos, cosmic rays and gravitational waves) from numerous origins. They give us information about their sources in the universe and the properties of the intergalactic medium. [...]

ESCAPE (European Science Cluster of Astronomy & Particle physics ESFRI research infrastructures) is an EU H2020 project that addresses the Open Science challenges shared by the astrophysics and and accelerator-based physics and nuclear physics ESFRI projects and landmarks. This project is embedded in the context of the European Open Science Cloud (EOSC) and involves activities to develop a prototype Data Lake and Science Platform, as well as support of an Open Source Software Repository, connection of the Virtual Observatory framework to EOSC, and engaging the public in citizen science.

The High Energy Stereoscopic System (H.E.S.S.) is a system of Imaging Atmospheric Cherenkov Telescopes (IACTs) located in the Khomas Highland in Namibia. It measures cosmic gamma rays of very high energies (VHE; $>100$) GeV using the Earth's atmosphere as a calorimeter. [...]

Infrared QCD and the Renormalisation Group
/ Litim, Daniel F. (CERN ; Southampton U.) ; Pawlowski, Jan M. (Erlangen - Nuremberg U., Theorie III) ; Nedelko, Sergei (Erlangen - Nuremberg U., Theorie III) ; von Smekal, Lorenz (Erlangen - Nuremberg U., Theorie III)
We study the infrared regime of QCD by means of a Wilsonian renormalisation group. We explain how, in general, the infrared structure of Green functions is deduced in this approach. [...]

The XYU-GEM: Ambiguity-free coordinate readout of the Gas Electron Multiplier
/ Flöthner, K J (CERN ; Bonn U., HISKP) ; Janssens, D (CERN ; Brussels U., IIHE ; Vrije U., Brussels) ; Brunbauer, F (CERN) ; Ferry, S (CERN) ; Ketzer, B (Bonn U., HISKP) ; Lisowska, M (CERN ; IRFU, Saclay) ; Muller, H (CERN ; Bonn U.) ; de Oliveira, R (CERN) ; Oliveri, E (CERN) ; Orlandini, G (CERN ; Erlangen - Nuremberg U.) et al.
We describe the development of a position-sensitive Gas Electron Multiplier detector prototype, providing for each ionizing event three coordinates: the cartesian X and Y, and U at 45°. Simultaneous recording of the three projections permits ambiguity-free reconstruction of multiple tracks, and aims at operation in very high intensity radiation fields..
