1.   As a bonus, at least one major neutrino detector might see a sign that all the atoms in the universe are doomed to eventual decay.

2.   For all neutrino detectors, it is vital to screen out particles like Muons and cosmic rays that can simulate neutrino collisions.

3.   For this reason, all neutrino detectors look down through the Earth rather than up into the sky.

4.   If a muon happens to hit a neutrino detector consisting of water, it creates the same kind of light signal used to detect neutrinos.

5.   Like all major neutrino detectors, the Sudbury observatory is deep underground to shield it from cosmic rays that could mask the faint neutrino signals.

6.   Like other large neutrino detectors, SNO mainly consists of a huge water tank.

7.   Neutrino detectors must record the effects of these rare collisions with atoms, or measure losses in particle energies attributable to the emission of neutrinos.

8.   That includes the cost of buying a neutrino detector and other equipment and conducting experiments.

9.   The name refers to a big Japanese particle accelerator called KEK and to the underground neutrino detector called Super-Kamiokande at the Kamioka Observatory near here.

10.   They re-emerged on the other side of Earth, where they were sensed by neutrino detectors in Japan, Italy and Ohio.
