The $\bar{K}N$ system at threshold is a sensitive testing ground for low energy QCD, especially the explicit chiral symmetry breaking. Therefore, we have measured $K$-series x rays of kaonic hydrogen atoms DA$\Phi$NE electron-positron collider Laboratori Nazionali di Frascati, and determined most precise values strong-interaction energy-level shift width $1s$ atomic state. As x-ray detectors, used large-area silicon drift detectors having excellent timing resolution, which were developed...
Treatments delivered by proton therapy are affected uncertainties on the range of beam within patient, requiring medical physicists to add safety margins penetration depth beam.

Abstract Sterile neutrinos appear in minimal extensions of the Standard Model particle physics. If their mass is keV regime, they are viable dark matter candidates. One way to search for sterile a laboratory-based experiment via analysis β -decay spectra, where new neutrino eigenstate would manifest itself as kink-like distortion spectrum. The objective TRISTAN project extend KATRIN setup with multi-pixel silicon drift detector system keV-scale signal. In this paper we describe requirements...
Embedding signal processing in the front-end of radiation detectors represents an approach to cope with growing complexity nuclear imaging scanners increasing field view (i.e., higher number channels). Machine learning (ML) offers a good compromise between intrinsic image reconstruction performance and computational power. While most hardware accelerators for ML are based on digital circuits and, thus, require analog-to-digital conversion all individual signals from photodetectors, analog...

The complex electronic structure of metallic ferromagnets is determined by a balance between exchange interaction, electron hopping leading to band formation, and local Coulomb repulsion.
