Following the Long-Term Evolution of sp-type Defects in Tritiated Graphene using Raman Spectroscopy
Genrich Zeller, Magnus Schlösser, Helmut H. Telle
We report on the evolution of tritium-induced sp-defects in monolayer graphene on a Si/SiO substrate, by comparing large-area Raman maps of the same two samples, acquired j…
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…
The Generation and Analysis of Tritium-substituted Methane
Deseada Díaz Barrero, Thanh-Long Le, Simon Niemes +4
An unavoidable category of molecular species in large-scale tritium applications, such as nuclear fusion, are tritium-substituted hydrocarbons; these form by radiochemical reaction…
Precision measurement of the electron energy-loss function in tritium and deuterium gas for the KATRIN experiment
M. Aker, A. Beglarian, J. Behrens +132
The KATRIN experiment is designed for a direct and model-independent determination of the effective electron anti-neutrino mass via a high-precision measurement of the tritium -…
Analysis methods for the first KATRIN neutrino-mass measurement
M. Aker, K. Altenmüller, A. Beglarian +126
We report on the data set, data handling, and detailed analysis techniques of the first neutrino-mass measurement by the Karlsruhe Tritium Neutrino (KATRIN) experiment, which probe…
Suppression of Penning discharges between the KATRIN spectrometers
M. Aker, K. Altenmüller, A. Beglarian +151
The KArlsruhe TRItium Neutrino experiment (KATRIN) aims to determine the effective electron (anti)neutrino mass with a sensitivity of (90 C.L.) by precise…
Gamma-induced background in the KATRIN main spectrometer
