Description

Neutrino-nucleus interaction is one of the major sources of the uncertainty for neutrino oscillation experiments. The NINJA experiment aims to measure neutrino-water interactions containing low momentum secondary particles using a nuclear emulsion detector. Since nuclear emulsion has sub-micron position resolution, it allows us to observe the interaction vertices clearly, and is one of the most effective ways to measure low momentum secondary particles. Short proton tracks down to 200MeV/c momentum are expected to be measured which are hardly reconstructed in plastic scintillator based detectors. A series of test experiments has been carried out with prototype detectors at J-PARC. The latest run has $0.7\times10^{21}$ POT of anti-neutrino exposure on 4 kg water-target. More than 100 events of Charged-Current interactions on water are expected to be observed. Comparison between data and Monte Carlo simulation including track multiplicity and momentum distribution of secondary particles will be shown.
