The Design, Construction, and Commissioning of the KATRIN Experiment
M. Aker, K. Altenmüller, J. F. Amsbaugh +226
The KArlsruhe TRItium Neutrino (KATRIN) experiment, which aims to make a direct and model-independent determination of the absolute neutrino mass scale, is a complex experiment wit…
Experimental evidence of (M1+E2) mixed character of the 9.2 keV transition in Th and its consequence for spin-interpretation of low-lying levels
A. Kovalík, A. Kh. Inoyatov, L. L. Perevoshchikov +4
The 9.2 keV nuclear transition in Th populated in the -decay of Ac was studied by means of the internal conversion electron spectroscopy. Its multipolarity was p…
Analysis methods for the first KATRIN neutrino-mass measurement
M. Aker, K. Altenmüller, A. Beglarian +126
We report on the data set, data handling, and detailed analysis techniques of the first neutrino-mass measurement by the Karlsruhe Tritium Neutrino (KATRIN) experiment, which probe…
Suppression of Penning discharges between the KATRIN spectrometers
M. Aker, K. Altenmüller, A. Beglarian +151
The KArlsruhe TRItium Neutrino experiment (KATRIN) aims to determine the effective electron (anti)neutrino mass with a sensitivity of (90 C.L.) by precise…
High-resolution spectroscopy of gaseous Kr conversion electrons with the KATRIN experiment
K. Altenmüller, M. Arenz, W. -J. Baek +124
In this work, we present the first spectroscopic measurements of conversion electrons originating from the decay of metastable gaseous Kr with the Karlsruhe Tritium…
Gamma-induced background in the KATRIN main spectrometer
K. Altenmüller, M. Arenz, W. -J. Baek +123
The KATRIN experiment aims to measure the effective electron antineutrino mass with a sensitivity of 0.2 eV/c using a gaseous tritium source combined with th…
