TL;DR: An upper limit of 1.1 eV (90% confidence level) is derived on the absolute mass scale of neutrinos on the Karlsruhe Tritium Neutrino experiment KATRIN, which improves upon previous mass limits from kinematic measurements by almost a factor of 2 and provides model-independent input to cosmological studies of structure formation.

TL;DR: Kassiopeia as discussed by the authors is an object-oriented software package using modern C++ techniques, written originally to meet the needs of the Katrin collaboration, which is capable of simulating particle trajectories governed by arbitrarily complex differential equations of motion.

TL;DR: In this article, a consistent theoretical description of the electron energy spectrum in the endpoint region, an accurate model of the apparatus response function, and the statistical approaches suited to interpret and analyze tritium data observed with KATRIN with the envisaged precision are presented.

TL;DR: Arenz et al. as mentioned in this paper presented the configuration, the commissioning with bake-out at 300◦C, and the performance of this system and demonstrated that the performance is already close to these stringent functional requirements for the KATRIN experiment, which will start at the end of 2016.
