Description
The NINJA collaboration aims to study neutrino-nucleus interactions in the energy range of hundreds of MeV to a few GeV using an emulsion-based detector. Nuclear emulsion is suitable for precise measurement of positions and angles of charged particles from neutrino interactions since it has a sub-$\mu$m spatial resolution. It is capable of detecting slow protons as low as 200$\,$MeV/$c$, which is a distinct advantage compared to other detectors. Data in this presentation was taken from the exposure of a 65$\,$kg iron target in 2016 to the neutrino beam corresponding to $4.0 \times 10^{19}$ protons on target. Based on 183 candidate events of neutrino-iron charged current interactions in the target, the cross section was successfully measured using the emulsion detector. In addition, multiplicities and kinematics of muons, charged pions and protons emitted from the events were measured and compared with a Monte Carlo simulation. We will present these results of the NINJA 65$\,$kg iron target run.
