Outline of Final Research Achievements

The development of the analysis method and the data analysis have been performed for the purpose of the initial analysis of the cosmic ray nuclei which have been observed by the CALET detector onboard the International Space Station.
At first, the development and the improvement of the track reconstruction algorithm have been done as same as the alignment calibration of the scintillating fibers in the detector. These have successfully improved the accuracy of the track reconstruction.Then the analysis of the observed data has been done basing on the established charge determination and energy estimation procedures. The detection efficiencies have been calculated in parallel with simulation calculations.
The absolute fluxes of proton and helium, the ratio of boron relative to carbon are now under calculation basing of above results.
