KATRIN Sensitivity to keV Sterile Neutrinos with the TRISTAN Detector Upgrade
H. Acharya, M. Aker, D. Batzler +127
Sterile neutrinos in the keV mass range are a well-motivated extension of the Standard Model and viable dark matter candidates. Their existence can be probed in laboratory experime…
Cyclotron Radiation Signal Characterization in Resonant Cavities for the Project 8 Neutrino Mass Experiment
A. Ashtari Esfahani, S. Bhagvati, H. P. Binney +60
Many experimental methods in physics require understanding radiation from single particles into non-trivial electromagnetic mode structures. Such characterization is critical for C…
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…
Antenna Arrays for CRES-based Neutrino Mass Measurement
A. Ashtari Esfahani, S. Bhagvati, S. Böser +65
CRES is a technique for precision measurements of kinetic energies of charged particles, pioneered by the Project 8 experiment to measure the neutrino mass using the tritium endpoi…
Sterile-neutrino search based on 259 days of KATRIN data
Himal Acharya, Max Aker, Dominic Batzler +132
Neutrinos are the most abundant fundamental matter particles in the Universe and play a crucial role in particle physics and cosmology. Neutrino oscillation, discovered about 25 ye…
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…
