COSMIC PLASMA PHYSICS Proceedings of the Conference on Cosmic Plasma Physics Held at the European Space Research Institute (ESRIN), Frascati, Italy, September 20-24, 1971

The plan to hold a conference on cosmic plasma physics originated in the Plasma Physics Division of the European Physical Society, whose chairman, B. Lehnert, took the first steps towards its realization. - ESRIN readily adopted this idea, and preliminary contacts with a number of other groups showed that there was a good deal of interest in bringing to­ gether people working in different areas of the field of cosmic plasma physics. It was clearly felt that an exchange of views and experience, and an attempt to define problem areas, would be profitable. In this spirit a programme was de­ vised which covered a large variety of topics, ranging from ionospheric to galactic structures. A diversified programme of this kind runs the risk that the communication between the various fields of specialization remains insufficient. It was gratifying to find that within the wide field of cosmic plasma physics a lively dialogue was in fact possible. The Conference was sponsored by the European Physical Society. Financial support was provided by ESRO. It is a pleasure to acknowledge the excellent suggestions of the programme committee members L. Biermann, N. D'Angelo, R. Gendrin, and B. Lehnert. I should like to thank my colleagues B. Bertotti, K. Lackner, and J.F. McKenzie, and numerous other ESRIN staff members, for their valuable help. I feel particularly indebted to the conference secretary, Miss Sachs, who did the real work while I just signed the letters.
