Comparison of the detector response and calibration function of metallic microcalorimeters for X-ray photons and external electrons
Neven Kovac, Fabienne Adam, Sebastian Kempf +6
Metallic microcalorimeters (MMCs) are cryogenic single-particle detectors that rely on a calorimetric detection principle. Due to their excellent energy resolution, close-to-ideal…
Graphene structure modification under tritium exposure: 3H chemisorption dominates over defect formation by \b{eta}-radiation
Alexandra Becker, Genrich Zeller, Holger Lippold +6
Potential structural modifications of graphene exposed to gaseous tritium are important for membrane-based hydrogen isotope separation. Such modifications cannot be explained by el…
Direct neutrino-mass measurement based on 259 days of KATRIN data
M. Aker, D. Batzler, A. Beglarian +146
The fact that neutrinos carry a non-vanishing rest mass is evidence of physics beyond the Standard Model of elementary particles. Their absolute mass bears important relevance from…
Demonstration of tritium adsorption on graphene
Genrich Zeller, Desedea Diaz Barrero, Paul Wiesen +9
In this work, we report on studies of graphene exposed to tritium gas in a controlled environment. The single layer graphene on a /Si substrate was exposed to 400 m…
