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…
Bound on 3+1 active-sterile neutrino mixing from the first four-week science run of KATRIN
M. Aker, K. Altenmueller, A. Beglarian +126
We report on the light sterile neutrino search from the first four-week science run of the KATRIN experiment in~2019. Beta-decay electrons from a high-purity gaseous molecular trit…
An improved upper limit on the neutrino mass from a direct kinematic method by KATRIN
M. Aker, K. Altenmüller, M. Arenz +205
We report on the neutrino mass measurement result from the first four-week science run of the Karlsruhe Tritium Neutrino experiment KATRIN in spring 2019. Beta-decay electrons from…
The KLM+KLN Auger electron spectrum of rubidium in different matrices
A. Kh. Inoyatov, A. Kovalík, L. L. Perevoshchikov +5
The KLM+KLN Auger electron spectrum of rubidium (Z=37) emitted in the electron capture decay of radioactive Sr in a polycrystalline platinum matrix and also Sr in pol…
Reduction of stored-particle background by a magnetic pulse method at the KATRIN experiment
KATRIN Collaboration, M. Arenz, W. -J. Baek +127
The KATRIN experiment aims to determine the effective electron neutrino mass with a sensitivity of (90\% C.L.) by precision measurement of the shape of the t…
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-…
Feasibility of photoelectron sources for testing the energy scale stablity of the KATRIN beta-ray spectrometer
O. Dragoun, A. Spalek, J. Kaspar +5
Photoabsorption of nuclear gamma-rays in thin metallic convertors was examined with the aim to produce monoenergetic photoelectrons of kinetic energy around 18.6 keV and natural wi…
Long term stability of the energy of conversion electrons emitted from solid 83Rb/83mKr source
D. Venos, J. Kaspar, M. Zboril +8
The mono-energetic conversion electrons from the decay of 83mKr represent a unique tool for the energy calibration, energy scale monitoring and systematic studies of the tritium be…
Final Results from phase II of the Mainz Neutrino Mass Search in Tritium Decay
Ch. Kraus, B. Bornschein, L. Bornschein +8
The paper reports on the improved Mainz experiment on tritum spectroscopy which yields a 10 times' higher signal to background ratio than before. The main experimental effects…
