A high-dose gamma-irradiation facility has been developed for irradiation experiments in the spent fuel elements (SFE) at the research reactor FRM II. The irradiation is performed underwater [...]

Piezoelectric materials are a unique class of functional materials that have attracted significant attention for their ability to convert mechanical energy to electrical energy and vice versa. Their fast response speed and high precision make them highly valuable for energy harvesting applications. [...]

Zwischen Anspruch und Wirklichkeit der Energiewende klafft eine technische Lücke. Zwar bilden erneuerbare Energien das Rückgrat der Transformation, doch sie allein reichen nicht aus. [...]

This paper investigates the impact of residual-stress-based flux barriers on the performance of permanent magnet synchronous machines (PMSMs) by using finite element analysis. In contrast to conventional cutout-based flux barriers, which improve magnetic anisotropy but compromise mechanical strength, residual-stress-based flux barriers improve structural integrity. [...]

Antihydrogen formation at AEgIS at CERN leverages charge exchange between Rydberg positronium (Ps*) and antiprotons, with cross-sections scaling with the Ps principal quantum number n4 and inversely with relative velocity v−2. However, the motional Stark effect and velocity mismatch between Ps and antiprotons impose stringent constraints, limiting efficiency. [...]

The AEgIS (Antimatter Experiment: Gravity, Interferometry and Spectroscopy) project, based at CERN's Antiproton Decelerator (AD) facility seeks to probe the Weak Equivalence Principle (WEP) for antimatter. It has undergone significant enhancements, capitalizing on the increased quantity of colder antiprotons made available by the Extra Low Energy Antiproton Ring (ELENA) decelerator. [...]

The experimental demonstration of positronium laser cooling with stationary broadband laser pulses with negative detuning is briefly described. Considerations on the limits of the current experiment and possible future developments follow. [...]

The AEgIS experiment at CERN is pioneering measurements of gravity, spectroscopy, and interferometry using pulsed antimatter atomic sources. This work provides an overview of the AEgIS experimental setup and highlights recent advancements in antihydrogen production, positronium laser cooling, and the creation of antiprotonic atoms. [...]

Residual stress is a complex engineering phenomenon that can either enhance component performance or lead to catastrophic failure, making understanding and control essential for successful design. The articles in this volume explore the main challenges faced by design and structural analysis engineers as they try to balance using residual stresses for better performance with identifying and reducing unwanted stresses that could threaten the design intent.
