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…
Calibration of Troitsk nu-mass detector readout electronics by signal digital filters
S. B. Abdiganieva, A. I. Berlev, M. A. Bochkov +3
We present the results of tuning and calibration of the detector electronics in the signal digitization mode. The goal of the experiment is to search for a possible sterile neutrin…
Measurements with a TRISTAN prototype detector system at the "Troitsk nu-mass" experiment in integral and differential mode
Tim Brunst, Thibaut Houdy, Susanne Mertens +22
Sterile neutrinos emerge in minimal extensions of the Standard Model which can solve a number of open questions in astroparticle physics. For example, sterile neutrinos in the keV-…
First operation of the KATRIN experiment with tritium
M. Aker, K. Altenmüller, M. Arenz +168
The determination of the neutrino mass is one of the major challenges in astroparticle physics today. Direct neutrino mass experiments, based solely on the kinematics of beta-decay…
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…
First measeurements in search for keV-sterile neutrino in tritium beta-decay by Troitsk nu-mass experiment
J. N. Abdurashitov, A. I. Belesev, V. G. Chernov +11
We present the first measurements of tritium beta-decay spectrum in the electron energy range 16-18.6 keV. The goal is to find distortions which may correspond to the presence of a…
Electron scattering on hydrogen and deuterium molecules at 14-25 keV by the "Troitsk nu-mass" experiment
D. N. Abdurashitov, A. I. Belesev, V. G. Chernov +9
We've performed precise measurements of electron scattering on molecular hydrogen and deuterium by using the "Troitsk nu-mass" setup. Electrons were generated by the electron gun w…
The current status of "Troitsk nu-mass" experiment in search for sterile neutrino
D. N. Abdurashitov, A. I. Belesev, A. I. Berlev +15
We propose a new experiment to search for a sterile neutrino in a few keV mass range at the "Troitsk nu-mass" facility. The expected signature corresponds to a kink in the electron…
The KATRIN Pre-Spectrometer at reduced Filter Energy
M. Prall, P. Renschler, F. Glück +13
The KArlsruhe TRItium Neutrino experiment, KATRIN, will determine the mass of the electron neutrino with a sensitivity of 0.2 eV (90% C.L.) via a measurement of the beta-spectrum o…
An upper limit on electron antineutrino mass from Troitsk experiment
V. N. Aseev, A. I. Belesev, A. I. Berlev +10
An electron antineutrino mass has been measured in tritium beta-decay in the "Troitsk nu-mass" experiment. The setup consists of a windowless gaseous tritium source and an electros…
