Origin of high energy Galactic cosmic raysThe flux of cosmic ray antiprotons and the chemical composition in the region of the 'knee' of the cosmic ray energy spectrum are discussed. The importance of a direct determination of the energy spectrum of each major component of cosmic radiation through the knee region is stressed, and the necessary kinds of experiments are described. It is emphasized that antiprotons are a unique probe of acceleration and propagation of energetic particles in the galaxy because of the high threshold for their production.
