| Outline of Final Research Achievements |
In this project, I developed the analysis method of neutrino interactions at the range of sub-GeV to multi-GeV in order to provide the detail information，using a feature of fine position resolution of emulsion films. The method of electron energy measurement has been developed. As the result, it was shown that the energy (500MeV - 2GeV) is estimated with 70% error. The test exposure to the emulsion detector has been carried out at the neutrino beamline at J-PARC, which was equipped with emulsion shifter. Neutrino interactions have been detected and some secondary particles were added time information. And then they were matched with INGRID tracking information. New type emulsion with a thick base was developed and it has 2.7 times higher angle accuracy than current one.
