Weighing the Invisible

Friday Apr 17, 2026, 9:00 AM → 8:00 PM Europe/Berlin

FTU Aula (KIT)

The Karlsruhe Tritium Neutrino experiment (KATRIN) is nearing the conclusion of its precision measurement campaigns in the search for the neutrino mass.
Over more than 1,000 measurement days, the collaboration has probed the endpoint region of the tritium beta-decay spectrum with unprecedented sensitivity, setting new standards for precision direct neutrino-mass searches. While the analysis of the full dataset is still ongoing, the completion of this first measurement phase marks an important milestone.

We wish to celebrate this occasion with a symposium bringing together our colleagues from the international research community, collaborators, and institutional stakeholders whose support has been essential to advancing neutrino research. The event will highlight KATRIN’s scientific achievements and outline perspectives towards the future, with the TRISTAN and KATRIN++ phases.

We will entertain you with science talks on neutrino physics, greetings from all over the world, visits to the KATRIN experiment and accompanying music. 

We are looking forward to welcome you.
