A precision 32 keV angular-selective photoelectron source for calibration measurements at the KATRIN experiment
Sonja Schneidewind, Rudolf Sack, Fabian Block +11
The paper describes an upgraded monoenergetic, angular‑selective photoelectron source delivering up to 32 keV electrons for calibrating the KATRIN neutrino‑mass experiment.
An active Transverse Energy Filter based on microstructured Si-PIN diodes with an angular-selective detection efficiency
S. Schneidewind, K. Gauda, K. Blümer +10
Si-PIN detectors can be microstructured to achieve angular-selective particle detection capabilities, which we call active Transverse Energy Filter (aTEF). The microstructuring con…
Sterile-neutrino search based on 259 days of KATRIN data
Himal Acharya, Max Aker, Dominic Batzler +132
Neutrinos are the most abundant fundamental matter particles in the Universe and play a crucial role in particle physics and cosmology. Neutrino oscillation, discovered about 25 ye…
Measurement of the inhomogeneity of the KATRIN tritium source electric potential by high-resolution spectroscopy of conversion electrons from Kr
H. Acharya, M. Aker, D. Batzler +130
Precision spectroscopy of the electron spectrum of the tritium -decay near the kinematic endpoint is a direct method to determine the effective electron antineutrino mass. The…
First constraints on general neutrino interactions based on KATRIN data
M. Aker, D. Batzler, A. Beglarian +130
The precision measurement of the tritium -decay spectrum performed by the KATRIN experiment provides a unique way to search for general neutrino interactions (GNI). All theoret…
