Introduction T. Fukuda, NEUTRINO2016

There are many projects of next generation large scale neutrino experiments which aim at finding the CP violating phase in the PMNS matrix, probing the neutrino mass hierarchy, measuring ultra high energy cosmic neutrinos and so on.

Large detectors high statistics

Novel (near) detectors reducing systematic uncertainty

Summary • There are many projects of next generation large scale neutrino

experiments which aim at finding the CP violating phase in the PMNS matrix, probing the neutrino mass hierarchy, measuring ultra high energy cosmic neutrinos and so on.

• These experiment plan to discover the rare effects and study them by measuring neutrino interactions precisely with large detectors. Toward these goals, a lot of R&D activities for novel (near) detectors are also going on in order to reduce systematic uncertainties.

• In the next decade, these detector R&D and construction is essential to achieve the goal.

• In this talk, I Introduced some of Large Water Cherenkov, Large Schintillator, and Large Magnetized Iron Calorimeter Detectors. For novel detectors, Water target detectors are mainly reviewed. Then the nuclear emulsion detector for these purpose is introduced.
