When the experiment is up and running, neutrinos will be created at Fermilab by smashing protons into a target to produce pions and kaons, which then decay into neutrinos. “They are simple and abundant and a perfect tool for tuning up a new detector.” “Everybody loves cosmic rays for this reason,” explains Fermilab’s Mat Muether. While this is exactly what NOvA scientists want to discriminate against when they are looking for neutrinos, such events are very useful when it comes to calibrating the detector. The above image shows a large shower of energetic particles created by a muon, which itself was created by a cosmic ray. By studying these tracks, physicists should be able to discern between the extremely rare detection of a neutrino and the much more common background noise from cosmic rays. The Far Detector is a series of liquid-scintillator sectors, and particles are tracked as they move from sector to sector. These are not of neutrinos, but of the trajectories of fast-moving particles that are created in a process that begins with a cosmic ray colliding with Earth’s atmosphere. Designed to register the arrival of neutrinos that will be created 810 km away at Fermilab near Chicago, the detector has recorded its first 3D images.
