Study of neutrino charged current interactions on iron in the NINJA experiment

Emulsion Cloud Chamber with 65kg iron target was exposed to the neutrino beam at J-PARC neutrino beam line in 2016. It is capable of detecting short proton tracks down to 200 MeV/c. Data presented in this document corresponds to 0.40 x 10(2) POT. The 194 neutrino-iron charged current interactions were successfully reconstructed in the target. Numbers of protons and charged pions in the final state of each event were measured and compared with those of a Monte Carlo simulation.
