  The KamLAND detector is located in a cylindrical cavern of 20-meter diameter and 20-meter deep in the Kamioka Mine (Kamioka Town, Hida City, Gifu Prefecture) with 1000-meter’s rock overburden. Why the detector is located in such a deep underground ? Because it must be shielded against cosmic rays...

  In KamLAND, neutrinos are detected using 1000-ton of liquid scintillator. The amount of light produced by charged particles in liquid scintillator is several tens of times larger than that of Cherenkov light at Kamiokande. Therefore, lower energy neutrinos can be detected using the liquid scintillator...

  The liquid scintillator in the balloon and the buffer oil are contained in a 18-meter diameter spherical stainless steel tank (3000m^3). On the surface, this tank looks like a large green gas tank existing everywhere. However,the difference from these gas tanks is that it is made of stainless steel to...

  Between the stainless steel spherical tank and the detector cavity, 3000m^3 (3000ton) of ultrapure water is filled and the spherical tank sinks in it completely. Also, the ultrapure water is surrounded with 255 20-inch PMTs and serves two important functions. One is to detect cosmic-ray muons traversing...
