CERN Accelerating science

Geant4 Users' Workshop, November 2002

Geant4 Users' Workshop


CERN, European Organization for Nuclear Research
November 11 - 15, 2002



This workshop is the first Geant4 users workshop to be held at CERN. The workshop consists of tutorials and presentations. Tutorials start at the novice level, which is aimed at the people who are new to Geant4, then proceed to advanced lectures for experienced users. Presentations are planned both from Geant4 users in various application fields and from Geant4 developers. Participants will be strongly encouraged to describe their own applications. Opportunities for discussions among users and developers will be scheduled.

The workshop will take place from November 11 through 15, 2002 at CERN, Geneva, Switzerland.
