These conferences are the major forum for dissemination of new research results by cosmic ray physicists. The proceedings cover all aspects of research on cosmic ray: observations of cosmic rays from ground-based large detector arrays, balloon-borne instruments and satellite detectors; observations of radio waves and gamma rays produced by cosmic rays in distant galaxies, supernova remnants in our own galaxy, and around other objects such as neutron stars and even our own sun; propagation of cosmic rays within the production source, within the galaxy and within the solar system and near earth environment; theoretical models for production of cosmic rays; cosmic rays as a probe of particle physics at high energy.
