Professor of physics Joseph Formaggio is part of the team of scientists that will get a first look at KATRIN's data as they come in. Formaggio and others from MIT helped construct part of the detector's apparatus and developed software to simulate the trajectory of particles passing through the detector. His group is now working along with a team of scientists around the world on software to analyze the data for signs of neutrino mass. MIT News sat down with Formaggio ahead of the experiment's launch, for a chat about KATRIN and the monumental structure built to search for an infinitesimal signal.

Q: How will KATRIN measure the mass of a neutrino?
