Discovering the Secrets of Neutrinos
 |
When operating at the highest intensity, the NuMI beam line will transport a package of 20,000 billion protons every two seconds to a graphite target. The target converts the protons into bursts of particles with exotic names such as kaons and pions. Like a beam of light emerging from a flashlight, the particles form a wide cone when leaving the target. A set of two special lenses, called horns (pictured), is the key instrument to focus the beam and send it in the right direction. The beam particles decay and produce muon neutrinos, which travel in the same direction.FULL STORY >>
