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…
Tritium Beta Spectrum and Neutrino Mass Limit from Cyclotron Radiation Emission Spectroscopy
Project 8 Collaboration, A. Ashtari Esfahani, S. Böser +56
The absolute scale of the neutrino mass plays a critical role in physics at every scale, from the particle to the cosmological. Measurements of the tritium endpoint spectrum have p…
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…
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 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…
