global fundamental search effort to determine the mass of neutrinos.

What is the mass of neutrinos?  To answer one of the most fundamental and important open questions in modern particle physics and cosmology, the KATRIN experiment was designed and built by an international collaboration at Karlsruhe Institute of Technology (KIT) in southwest Germany. A special Inauguration Colloquium on June 11 marked the start of its long-term data taking phase.

KATRIN now starts to weigh the mass of neutrinos. Following the electrostatic spectrometer and the detector unit, the tritium source was installed as the last of the large components of KATRIN. The ambitious and highly motivated team of physicists, engineers, and technicians is well-trained and looks forward to the challenges in determining the neutrino mass.

Germany’s Federal Minister of Research Anja Karliczek said ”KATRIN is an experiment of superlatives and will complement the knowledge about our universe by a decisive piece of the puzzle.”

APPEC strongly supports the present range of direct neutrino-mass measurements and searches for neutrino-less double-beta decay. Guided by the results of experiments currently in operation and in consultation with its global partners, APPEC intends to converge on a roadmap for the next generation of experiments into neutrino mass and nature by 2020.
