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 K…
Search for keV-scale Sterile Neutrinos with first KATRIN Data
M. Aker, D. Batzler, A. Beglarian +128
In this work we present a keV-scale sterile-neutrino search with the first tritium data of the KATRIN experiment, acquired in the commissioning run in 2018. KATRIN performs a spect…
Search for Lorentz-Invariance Violation with the first KATRIN data
M. Aker, D. Batzler, A. Beglarian +130
Some extensions of the Standard Model of Particle Physics allow for Lorentz invariance and Charge-Parity-Time (CPT)-invariance violations. In the neutrino sector strong constraints…
KATRIN: Status and Prospects for the Neutrino Mass and Beyond
M. Aker, M. Balzer, D. Batzler +159
The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to measure a high-precision integral spectrum of the endpoint region of T2 beta decay, with the primary goal of probi…
New Constraint on the Local Relic Neutrino Background Overdensity with the First KATRIN Data Runs
M. Aker, D. Batzler, A. Beglarian +129
We report on the direct cosmic relic neutrino background search from the first two science runs of the KATRIN experiment in 2019. Beta-decay electrons from a high-purity molecular…
Improved eV-scale Sterile-Neutrino Constraints from the Second KATRIN Measurement Campaign
M. Aker, D. Batzler, A. Beglarian +128
We present the results of the light sterile neutrino search from the second KATRIN measurement campaign in 2019. Approaching nominal activity, tritium -electr…
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…
