The KATRIN experiment

Neutrinos are the most abundant matter particles of the Universe, but also the lightest! In 2015 the Nobel prize was awarded for the discovery of neutrino oscillations, which shows that neutrinos have mass. Their tiny mass is a compelling evidence for physics beyond the standard model of elementary particle physics. 

The absolute value of the neutrino masses is very important in understanding, which of the possible extensions or new theories beyond the Standard Model of particle physics is the right one.  In addition it is highly relevant for astrophysics and cosmology, because of the role of neutrinos in the formation of structures in the Universe. 

The current best laboratory upper limit to the electron anti-neutrino mass is 2.3 eV/c², by former experiments at Mainz and Troitsk. KATRIN will use similar techniques to improve the sensitivity by one order of magnitude down to 0.2 eV/c² (90% CL) or to discover the actual mass, if it is larger than 0.35 eV/c². This requires an improvement by two orders of  the detector systematic uncertainties.

The KArlsruhe TRItium Neutrino (KATRIN) experiment will investigate the absolute mass scale of electron neutrinos. The experimental setup is currently being commissioned at Tritium Laboratory Karlsruhe on the KIT Campus North site. KATRIN is designed to achieve an overall neutrino mass sensitivity of 200 meV at 90% C.L. after 3 years of data taking. The international KATRIN Collaboration consists of more than 150 scientists, engineers, technicians and students from 12 institutions in Germany, the United Kingdom, the Russian Federation, the Czech Republic, the United States, and France via the participation of CEA.
