| Outline of Final Research Achievements |
The Galactic cosmic rays are considered to be originated in supernova remnants (SNR) by considerations of energetics, detections of very high energy gamma ray emissions from SNRs, and quite effective acceleration by the associated shock waves. We numerically investigated the propagation process of the cosmic rays from SNRS where they are accelerated to the solar system based on stochastic differential equation methods by fully taking into account the discreteness of the occurrences of supernova explosions in the Galaxy. Calculated energy dependence of B/C which is the most important parameters to characterize the propagation process nicely agrees with the recent observational results by AMS-02. This result suggests the structure of turbulent interstellar magnetic field is described by the Kraichnan model.
