This issue of Laser and Particle Beams contains 25
papers that were presented at the conference on “Matter
in Super-Intense Laser Fields: Short Pulse, Superstrong
Laser-Plasma Interactions,” held in S. Feliu de Guixols,
Spain, from 29 September to 4 October 2001. Almost 100 scientists
and young researchers (Ph.D. students and Post Docs) took part
in this successful event, despite the terrible terrorist acts
of September 11, 2001 in New York, which prevented many speakers
from taking part, especially those coming from the United States.
