Neutrino Search
A hard-to-observe fundamental particle that travels alone, the neutrino has little or no mass, so rarely interacts with other particles.
Neutrinos are ubiquitous throughout our universe. They were produced during the Big Bang, and many of those are still around. New ones are constantly being created too, through natural occurrences like solar fusion in the sun's core, or radioactive elements decaying in the Earth's mantle, as well as when the particle accelerator at Fermilab purposely smashes protons into carbon foils.
Our sun produces so many that hundreds of billions are zinging through our bodies every second, Coan said. It's hoped the new detector can resolve questions surrounding three different kinds of neutrinos — electron, tau and muon — and their "oscillation" from one type to another as they travel, he said.
Scientists at the new detectors will analyze data from Fermilab's neutrino beam to observe evidence of neutrinos when the speedy, lightweight particles occasionally smash into the carbon nuclei in the scintillating oil of the detector, causing a burst of light flashes, Coan said.
NOvA is looking for the most elusive oscillation of the muon type of neutrino to the electron type, Cooper said.
