Trends in Astroparticle-Physics

From October 10 to 12, 1991 the Second International Conference on Trends in Astroparticle-Physics took place at Aachen, Germany. The meeting was the second in a series that started in 1990 at UCLA. It was attended by about 100 physicists from allover the world and covered the interface of elementary particles and astrophysics. Topics covered included Neutrino-Telescopes in preparation, high energy gamma ray physics, but also new ideas for future detectors. detectors, cosmology and particle Many people have worked hard on the preparation for the meeting and deserve many thanks, in particular D. Rein, L. Sehgal, U. Berson, G. Wurm, C. Wiebusch, C. Ley, and U. Braun. Representing the conference secretariat, I. Goidie, U. Packbier, and L. Jenckins were of great help. We also would like to thank the Stadtsparkasse Aachen, in particular Mr. Fischer, Mrs Cremers and Direktor Schwind for their support and providing the meeting facilities as well as making possible in parallel a public exhibition on the topic of the conference. Very special thanks goes to H. Geller, without whom this conference could not have taken place. Last but not least we wish to thank the speakers for taking their time in preparing their talks and presenting their results, making this publication possible.
