Explorations of Neutrino Detectors Here are some links to the homepages of neutrino "observatories" that are in operation around the world. All of the sites will be displayed in another window. 1. The Borexino detector uses 300 tons of liquid scintillator (an organic liquid much like mineral oil that gives off light when charged particles interact in it) to detect low-energy neutrinos produced in the Beryllium-7 electron-capture process in nuclear fusion in the Sun. It is buried far below a mountain in Italy. 2. The Sudbury Neutrino Observatory Plus (SNO+) will use 1000 tons of liquid scintillator (specifically, linear alkyl benzene, LAB) with dissolved neodymium buried far below ground outside of Sudbury, Ontario (Canada) to search for a particular neutrino reaction as well as being able to detect low-energy neutrinos. SNO+ is the followup to the Sudbury Neutrino Observatory that used 1000 tons of "heavy water" in the same container as SNO+. Heavy water uses the deuterium isotope of hydrogen instead of the
