Neutrinos interact with the main detector—a massive 14,000-ton device composed of about 344,000 small PVC plastic modules filled with a liquid, which emits light when a neutrino triggers the release of charged particles. “Detection is a challenge,” said Jeremy Wolcott. “We have to sort out oscillated neutrinos from the accelerator from unoscillated accelerator neutrinos, cosmic-ray particles, and other background particles that come in contact with the detector.”
