Detector (KamLAND)
Buried 1 kilometer under earth, in an old mine at the northwest of
Tokyo, the KamLand is waiting
for the neutrinos emitted by Japan's nuclear
power reactors. These particles are very reluctant to interact with matter,
which makes them difficult to be detected. They interact with other
subatomic particles only through weak forces, the forces involved in certain
radioactive decays. But they are not completely invisible. When a neutrino
collides with neutrons or protons in an atomic nuclei, some high-speed particles are produced. If this interaction has place in a medium in which the
velocity of these particles is greater than the velocity of light in this medium, these particles emit blue flashes of light known as Cherenkov radiation.
In most neutrino experiments the medium is water and the flashes of light are
detected by photomultiplier tubes placed around.
