Description
Understanding of neutrino-nucleus interactions for energies around 1 GeV is of great importance to us because one of the major systematic uncertainties in current neutrino oscillation experiments comes from nuclear effects in those interactions.
The NINJA collaboration aims to study neutrino-nucleus interactions in the energy range of hundreds of MeV to a few GeV by using emulsion-based detector. Nuclear emulsion is well suited for precise measurement of positions and angles of interacting particles since it has sub-micron spatial resolution. It is capable of detecting slow protons as low as 200 MeV/c, which is its advantage over other detectors.
In this talk, we use the data collected in 2016, corresponding to $0.40\times10^{20}$ protons on target. Based on a few hundred events in the target, we will present a measurement of the neutrino charged current cross section on iron with the emulsion cloud chamber (ECC). This is the first measurement using the iron ECC in this energy region.
