Outline of Final Research Achievements

I developed the large statistical analysis method of cosmic-ray emulsion chamber to analyze the balloon chambers (RUNJOB, JACEE), which was conducted a few years ago . These chambers recorded a huge amount of cosmic ray particles. I established the method of re-glycerine process of these emulsions to read out these films by using latest scanning system. And also, I established the analyzing method and validated the separation between proton and other heavy particles. In addition, I applied this method to measure cosmic-ray muon flux by using new emulsion chamber on the ground.
