Status of RI background reduction for SK-Gd

Super-Kamiokande Collaboration

Research output: Contribution to journalConference articlepeer-review


The Super Kamiokande-Gadolinium (SK-Gd) project is the upgrade of the Super-Kamiokande (SK) detector in order to discover Supernova Relic Neutrinos (SRNs) by loading 0.2% of Gd2(SO4)3 into a 50 kton of the SK water tank. In order to continue solar neutrino measurement with low energy threshold at ∼3.5 MeV, radioactive isotopes (RI) should be reduced before loading. In this talk, the methods to measure RI in Gd2(SO4)3 and the current status of RI background reduction will be presented.
