The 24th International Werner Brandt Workshop on Particle Penetration Phenomena and Excitations of Solids will be held at Humboldt-University Berlin, Germany, from July 12 - 14, 2004. We intend to continue a series of workshops which was held in recent years in Bariloche (Argentina, 1999), Gainesville (USA, 2000), San Sebastian (Spain, 2001), Namur (Belgium 2002), and Playa del Carmen (Mexico, 2003).

The workshop will focus on various topics of current interest in the field of particle-solid interactions as, e.g., dynamic effects in particle penetration and electronic excitations, nonlinear and many-body phenomena, charge exchange and screening in collisions with metal and insulators, processes at surfaces.

The members of the International Committee are: N. Arista, R. Baragiola, G. Basbas, O.H. Crawford, S. Cruz, P.M. Echenique, F.Flores, A. Lucas, R.H. Ritchie, J.R. Sabin, and Y. Yamazaki.

Local Organizing Committee: H. Winter, H. Niehus, M. Busch, M. Gruyters, S. Lederer, A. Mertens
