Gaseous Tritium Activity Monitoring with Scintillators (GaTAMoS)
Florian Priester, Alexander Marsteller, Johanna Wydra +1
We present a novel device for the inline activity monitoring of gaseous tritium, named Gaseous Tritium Activity Monitoring with Scintillators (GaTAMOS). Unlike established methods…
KATRIN Sensitivity to keV Sterile Neutrinos with the TRISTAN Detector Upgrade
H. Acharya, M. Aker, D. Batzler +127
Sterile neutrinos in the keV mass range are a well-motivated extension of the Standard Model and viable dark matter candidates. Their existence can be probed in laboratory experime…
Neutrinoless Double Beta Decay Sensitivity of the XLZD Rare Event Observatory
XLZD Collaboration, J. Aalbers, K. Abe +441
The XLZD collaboration is developing a two-phase xenon time projection chamber with an active mass of 60 to 80 t capable of probing the remaining WIMP-nucleon interaction parameter…
Temperature dependent ultracold neutron transmission in D gas a test of the Young-Koppel model
G. Bison, R. Grössle, K. Kirch +4
The Young-Koppel model (YK) describes comprehensively the interaction of slow neutrons with diatomic gases such as H and D. This paper reports on the first experimental res…
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…
Cosmogenic background simulations for the DARWIN observatory at different underground locations
M. Adrover, L. Althueser, B. Andrieu +180
Xenon dual-phase time projections chambers (TPCs) have proven to be a successful technology in studying physical phenomena that require low-background conditions. With 40t of liqui…
ViMA -- the spinning rotor gauge to measure the viscosity of tritium between 77 and 300 K
Johanna Wydra, Alexander Marsteller, Robin Größle +2
Experimental values for the viscosity of the radioactive hydrogen isotope tritium (T) are currently unavailable in literature. The value of this material property over a wide t…
Viscosity measurements of gaseous H2 between 200 K to 300 K with a spinning rotor gauge
Johanna Wydra, Robin Größle, Alexander Marsteller +4
Experimental values for the viscosity of the radioactive hydrogen isotopologue tritium are still unknown in literature. Existing values from ab initio calculations disregard quantu…
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…
A Next-Generation Liquid Xenon Observatory for Dark Matter and Neutrino Physics
J. Aalbers, K. Abe, V. Aerne +591
The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leadi…
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…
First direct neutrino-mass measurement with sub-eV sensitivity
M. Aker, A. Beglarian, J. Behrens +125
We report the results of the second measurement campaign of the Karlsruhe Tritium Neutrino (KATRIN) experiment. KATRIN probes the effective electron anti-neutrino mass, , via…
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…
