Genesis and Propagation of Cosmic Rays [antikvár]

PREFACEThe fifth Course of the International School of Cosmic-Ray Astrophysics "Genesis and Propagation of Cosmic Rays," which gave rise to this volume, was held in June, 1986 at the Ettore Majorana Center for Scientific Culture (CCSEM) in Erice, Sicily. Its recognition and co-sponsorship as an Advanced Study Institute (ASI) by NATO contributed much to the success of the Course. Valuable support was also rendered by the European Physical Society,, the Italian Ministry of Education, the Italian Ministry of Scientific and Technological Research,the Sicilian Regional Government, and the National Science Foundation of the United States.For a decade the International School of Cosmic-Ray Astrophysics has consistently aimed to reflect the interdisciplinary character of this field of research. This Course was no exception; it extended the astrophysical horizons of students and senior participants. While the sessions were jnainly pedagogical, they also served as a workshop, dealing with current and controversial research issues. Nearly all participants were active investigators in cosmic radiation and related fields.The Editors, who were co-directors of the Institute, owe thanks to the sponsors and to many colleagues: notably to Lecturers and other participants who made this volume possible; to Professor Antonino Zi-chichi, Director of CCSEM; to Assistant Secretary General Professor Henry Durand and Dr. Craig Sinclair of NATO's Scientific Affairs Division; to the distinguished members of NATO's Scientific Committee; to Dr. Alberto Gabriele, Dr. Pinola Savalli and Ms. Sandra Wefel for unstinting administrative support. We acknowledge the patient editorial help of Ms. N. M. Pols-v.d. Heijden and her associates at the D. Reidel Publishing Company.Members of the Scientific Advisory Committee of the School have gi-ven timely advice: Professors Pierre Auger, G.P.S. Occhialini, Bruno Rossi, Maurice Shapiro (Director of the School), Rein Silberberg, John Simpson, James A. Van Allen, and Antonino Zichichi.This volume helps celebrate a noteworthy milestone in the history of cosmic raysthe seventy-fifth anniversary of their discovery.
