An active Transverse Energy Filter based on microstructured Si-PIN diodes with an angular-selective detection efficiency
S. Schneidewind, K. Gauda, K. Blümer +10
Si-PIN detectors can be microstructured to achieve angular-selective particle detection capabilities, which we call active Transverse Energy Filter (aTEF). The microstructuring con…

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…
