• New requirements
  • ATLAS group suggest to have alternative advance tool to scan detector geometry. It was pointed out, that in release 4.1, more advanced commands for detecting ovelapping regions are available. The stand-alone tool adopted by CMS in the IGUANA Framework is now available as an extended example.

Cuts per region

• Presented proposal of Architecture Subgroup.
• Constrain of the current proposal: only one set of cuts for each LogicalVolume.
• Initialisation time and memory increase should be investigated.

Geant4 workshop

• Date: 30 September - 4 October 2002
