Dynamics of Magnetic Evaporative Beamline Cooling for Preparation of Cold Atomic Beams

A. Ashtari Esfahani, S. Bhagvati, S. Böser +55

The most sensitive direct neutrino mass searches today are based on measurement of the endpoint of the beta spectrum of tritium to infer limits on the mass of the unobserved neutri…

Measurement of the inhomogeneity of the KATRIN tritium source electric potential by high-resolution spectroscopy of conversion electrons from Kr

H. Acharya, M. Aker, D. Batzler +130

Precision spectroscopy of the electron spectrum of the tritium -decay near the kinematic endpoint is a direct method to determine the effective electron antineutrino mass. The…

KARL -- A Monte Carlo model for atomic and molecular processes in the tritium atmosphere of the KATRIN experiment

Christian Sendlinger, Jonas Kellerer, Felix Spanier

A new parallelized simulation code is presented, which uses a Monte Carlo method to determine particle spectra in the KATRIN source. Reaction chains are generated from the decay of…

First constraints on general neutrino interactions based on KATRIN data

M. Aker, D. Batzler, A. Beglarian +130

The precision measurement of the tritium -decay spectrum performed by the KATRIN experiment provides a unique way to search for general neutrino interactions (GNI). All theoret…

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…
