Measurement of the electric potential and the magnetic field in the shifted analysing plane of the KATRIN experiment
M. Aker, D. Batzler, A. Beglarian +135
The projected sensitivity of the effective electron neutrino-mass measurement with the KATRIN experiment is below 0.3 eV (90 % CL) after five years of data acquisition. The sensiti…
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…
Precision Measurement of Vibrational Quanta in Tritium Hydride (HT)
F. M. J. Cozijn, M. L. Diouf, W. Ubachs +2
Saturated absorption measurements of transitions in the (2-0) band of radioactive tritium hydride (HT) are performed with the ultra-sensitive NICE-OHMS intracavity absorption techn…
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…
Operation Modes of the KATRIN Experiment Tritium Loop System using Kr
Alexander Marsteller, Beate Bornschein, Matthias Böttcher +12
The KArlsruhe TRItium Neutrino (KATRIN) experiment aims to search for the effective electron antineutrino mass with a sensitivity of 0.2 eV (90 % C.L.). In order to achieve this go…
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…
Rotational level spacings in HD from vibrational saturation spectroscopy
F. M. J. Cozijn, M. L. Diouf, V. Hermann +3
The R(1), R(3) and P(3) ro-vibrational transitions in the (2-0) overtone band of the HD molecule are measured in Doppler-free saturation using the technique of NICE-OHMS spectrosco…
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…
Monitoring of the operating parameters of the KATRIN Windowless Gaseous Tritium Source
M. Babutzka, M. Bahr, J. Bonn +21
The Karlsruhe Tritium Neutrino (KATRIN) experiment will measure the absolute mass scale of neutrinos with a sensitivity of $\m_ν$ = 200 meV/c by high-precision spectroscopy clo…
Accuracy of the Laser Raman system for KATRIN
M. Schlösser, S. Fischer, M. Hötzel +1
The aim of the Karlsruhe Tritium Neutrino experiment (KATRIN) is the direct (model-independent) measurement of the neutrino mass. For that purpose a windowless gaseous tritium sour…
