We invite you to visit the KArlsruhe TRItium Neutrino (KATRIN) Experiment located at KIT Campus North.
KATRIN is an international project for fundamental research. Its goal is to measure the neutrino mass by precisely analysing the beta-electron spectrum of tritium. Neutrinos are the most abundant particle species in the universe. They are described in the standard model of elementary particles as being massless. However, observations of solar and atmospheric neutrinos have led to the conclusion that neutrinos indeed carry a tiny, but non-zero mass. In order to determine this mass KATRIN uses a high-luminosity tritium source and a spectrometer with 10m in diameter. With this experimental setup KATRIN holds the world-best current limit on the neutrino mass of 0.8 eV at 90% confidence level and is continuing to take data for a target sensitivity of 0.2 eV.
