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…
High-resolution spectroscopy of gaseous Kr conversion electrons with the KATRIN experiment
K. Altenmüller, M. Arenz, W. -J. Baek +124
In this work, we present the first spectroscopic measurements of conversion electrons originating from the decay of metastable gaseous Kr with the Karlsruhe Tritium…
Solar Neutrino Detection Sensitivity in DARWIN via Electron Scattering
J. Aalbers, F. Agostini, S. E. M. Ahmed Maouloud +163
We detail the sensitivity of the liquid xenon (LXe) DARWIN observatory to solar neutrinos via elastic electron scattering. We find that DARWIN will have the potential to measure th…
Calibration of high voltages at the ppm level by the difference of Kr conversion electron lines at the KATRIN experiment
M. Arenz, W. -J. Baek, M. Beck +124
The neutrino mass experiment KATRIN requires a stability of 3 ppm for the retarding potential at -18.6 kV of the main spectrometer. To monitor the stability, two custom-made ultra-…
The KATRIN Superconducting Magnets: Overview and First Performance Results
M. Arenz, W. -J. Baek, M. Beck +121
The KATRIN experiment aims for the determination of the effective electron anti-neutrino mass from the tritium beta-decay with an unprecedented sub-eV sensitivity. The strong magne…
First transmission of electrons and ions through the KATRIN beamline
M. Arenz, W. -J. Baek, M. Beck +126
The Karlsruhe Tritium Neutrino (KATRIN) experiment is a large-scale effort to probe the absolute neutrino mass scale with a sensitivity of 0.2 eV (90% confidence level), via a prec…
