Adding New Volumes to G4 geometry Baseline

Alexander Sharmazanashvili, GCCEC

Requirements for Adding New Volumes Development of G4 geometry Baseline is

multidirectional activity Requirements for Adding:

Missing parts in G4 Detectors updates

CATIA tolls should be used for this activity We know CATIA well We now how to integrate in CATIA both “as built”

geometry and G4 We can use power of this tool itself

Models Anatomy

ST models in many of cases describing just outer envelops

ST models don’t have descriptions of materials
