Cosmic Ray Acceleration in Supernova Remnants and Transport in Galactic Magnetic Fields

The spectra of high-energy protons and nuclei accelerated by supernova blast waves are calculated for different types of supernova remnants during their evolution. The amplification of magnetic field by accelerated particles at the shock precursor is taken into account. The overall energy spectrum and elemental composition after propagation through the Galaxy are found and compared to the observations at the solar system.
