How much does a neutrino weigh? The KATRIN Experiment at KIT (2019)

Commissioning of the KATRIN experiment from 2001 to 2018

How heavy are neutrinos? This inconspicuous question is one of the most important questions in modern particle physics and cosmology. The Karlsruhe Tritium Neutrino (KATRIN) experiment brings us a big step closer to the answer. It was set up at the Karlsruhe Institute of Technology (KIT) by an international collaboration in a 15-year construction period and began its multi-year measurement in June 2018.

The video, an updated and extended version of a film already produced in 2012 (https://youtu.be/cnu79iC0C1M), shows how the international collaboration of 140 scientists and engineers intends to determine the neutrino mass with the KATRIN experiment. Neutrinos are the most common massive particles in the universe and thus a key particle in our understanding of the universe. Discussions with scientists will show why the neutrino mass, which has been sought for more than 80 years, is so important for fundamental questions in physics.
