Adding New Volumes to G4 geometry Baseline

1. Adding New Volumes to G4 geometry Baseline Alexander Sharmazanashvili, GCCEC

2. 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

3. Models Anatomy • ST models in many of cases describing just outer envelops • ST models don’t have descriptions of materials • “As-built” geometry and G4 using different sources SmarTeam ST Blue Print G4 / XML As-Built

4. ST Outer Envelops Reproduced Model in CATIA Using Manufacturing Drawings for Reproduction ST Model

5. ST vs G4 Comparison and Reproduction XML ST Models Repro-duction in CATIA Identification of Missing Parts CATIA Comparison G4 Volume ST Model

6. Simplification and XML coding Detailed Volume: ~4418cm3 Simplified Volume: ~4485cm3 CATIA Simplification XML Coding XML Coding

7. Loop for XML Overlaps Checking CATIA Crosscheck Simplified Model XML ATHENA VP1 .iv .WRL

8. New Volumes Adding Life Cycle G4 Volume XML ST Identification of Missing Parts CATIA Comparison ST Model Models Repro-duction in CATIA XML Coding Simplification in CATIA Update G4 with new XML ATHENA CATIA Crosscheck VP1 Nok Ok
