The International Symposium on Very High Energy Cosmic Ray Interactions (ISVHECRI) is a biennial conference series supported by the International Union of Pure and Applied Physics (IUPAP). Its primary objective is to provide a forum for the discussion of very high energy interactions for the interpretation of cosmic ray data based on the information available from both accelerator and cosmic ray experiments. This unique series brings together cosmic ray physicists and scientists involved with high energy accelerators and colliding beam facilities
