Contribution

It introduces a novel experimental setup with three detectors to improve measurement sensitivity of θ13 in reactor neutrino oscillation studies.

Findings

Design of a three-detector system for neutrino flux measurement

Potential to detect small neutrino flux deficits

Enhanced sensitivity to neutrino oscillation parameters

Abstract

A new reactor-neutrino oscillation experiment, KASKA, is proposed to measure the unknown neutrino-mixing angle $\theta_{13}$ using the world's most powerful Kashiwazaki-Kariwa nuclear power station. It will measure a very small deficit of reactor-neutrino flux using three identical detectors, two placed just close to the sources and one at a distance of about 1.8km. Its conceptual design and physics reach are discussed.
