Science: A small neutrino detector has been found to actually work!
Science News reports : A tiny neutrino detector scored big at a nuclear reactor Conventional detectors of the subatomic particles require metric tons of material. But the new detector has a mass of less than 3 kilograms. Think chihuahua. And it successfully detected antineutrinos , the antimatter counterparts of neutrinos, streaming from a nuclear power plant in Leibstadt, Switzerland, researchers report in a paper submitted January 9 to arXiv.org . “This is actually huge,” says neutrino physicist Kate Scholberg of Duke University, who was not involved with the research. “People have been trying to do this for many decades and now have finally succeeded.” Similar scaled-down neutrino detectors have glimpsed neutrinos and antineutrinos created by laboratory sources of the particles. Nuclear reactors spit out relatively low-energy antineutrinos. By measuring those low-energy particles, such detectors could help test physics theories or reveal the inner workings of atomic nuclei.
