Future Solar Neutrino Experiments

Solar neutrino experiments have resolved the long-standing puzzle of the missing neutrinos by the discovery of neutrino oscillations. This chapter presents a brief review of future experiments on solar neutrinos, indicating in particular their potential and the scale of time. These projects include the sudbury neutrino observatory+ at Sudbury, Canada; the Jiangmen Underground Neutrino Observatory (JUNO) project in south of China; the Low Energy Neutrino Astrophysics (LENA) collaboration at Pyhsalmi mine in Finland; the water Cherenkov Hyper-Kamiokande detector; and the deep underground neutrino experiment (DUNE) at Illinois and South Dakota in the United States. The JUNO project consists of new underground laboratory at a depth of about 700 m. The LENA collaboration involves the construction of a deep underground liquid scintillator detector with a total mass of about 50 kt. The DUNE is a next-generation project for neutrino physics and proton decay.
