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: In this paper, a detailed overview of the KATRIN experiment in its phase of building and testing of the first components is presented, along with the physical parameters as well as the schemes for the technical realization of the central experimental components and their status.

TL;DR: The first operation of KATRIN with tritium neutrino was reported in 2018, and stable conditions over a time period of 13 days could be established as discussed by the authors.

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.

TL;DR: The Karlsruhe Tritium Neutrino (KATRIN) experiment is a large-scale effort to probe the absolute neutrino mass scale with a sensitivity of 0.2 eV (90% confidence level) via a precise measurement of the endpoint spectrum of tritium β-decay.
