KamLAND is marked by the ability to detect anti-neutrino signals at 1,000 ton of ultra-pure liquid scintillator. In 2009 the KamLAND collaboration started a campaign to purify the liquid scintillator and ultimately achieved a twentyfold reduction of 210Po, the dominant background in the prompt energy region below 3.0 MeV. This reduction give a better signal-to-background ratio for the geo-neutrino flux estimation and enhances sensitivity to reactor neutrino oscillation below 2.6 MeV. Last year, we presented new knowledges concerning anti-neutrino studies …
