2. About the stave 2

3. Drawings : 3 Drawings on EDMS(cern) :EDMS Stave assembly : ATU-SYS-ED-0007, version 5,ATU-SYS-ED-0007, version 5 Stave omega : ATU-SYS-ED-0005, version 3,ATU-SYS-ED-0005, version 3 Stave pipe : ATU-SYS-ED-0011, version 3,ATU-SYS-ED-0011, version 3 Stave foam : ATU-SYS-ED-0004, version 3,ATU-SYS-ED-0004, version 3 Stave face plate : ATU-SYS-ED-0008, version 2,ATU-SYS-ED-0008, version 2 Stave end block – side A : ATU-SYS-ED-0006, version 5,ATU-SYS-ED-0006, version 5 Stave end block – side C : ATU-SYS-ED-0009, version 5,ATU-SYS-ED-0009, version 5 Stave middle leg : ATU-SYS-ED-0010, version 5,ATU-SYS-ED-0010, version 5 Half central ring : ATU-SYS-ED-0027, version 1,ATU-SYS-ED-0027, version 1 Blocage central : ATU-SYS-ED-0028, version 1,ATU-SYS-ED-0028, version 1 3D model on EDMS (in2p3): I-027361, V.2 : 16 aout 2011

4. Modules drawings 4 ATU-SYS-ED-0012 : Chip 3D sensor position, ATU-SYS-ED-0013 : Double chip planar sensor position layout, ATU-SYS-ED-0014 : Simple chip planar sensor position layout, No drawing about mix sensor choice !!!

5. Module on stave 5

6. IBL layout Stave orientation If α 12,24° Flex gap : 0,28 mm/1,058mm Module radius : R 33,25mm If α 14° Flex gap : 0,8 mm/1,405 mm Module radius : R 32,77mm 6

7. Prototype 7

8. Next step : part I – We need to validate details drawings, tolerances – IBL layout, (12,24° / 14°), – Sensors drawing (mix choice), – Interface : Flex, Beam Pipe, IST,….) – Reduce material (yes or no ?) – Prototype aluminium -> prototype PEEK PEEK from CERN, Machining at LPNHE Paris, – Planning… 8

9. Stave assembly on support With Unige 9

10. container 10 Length : 8900 mm !!!

11. Dummy stave -> Final stave 11 Length : 7000 mm (2750+1500+2750)

12. Assembly scenario 12

13. Next step : part II – We need : Final pieces (LPNHE Paris): – End ring side A – End ring side C – Centrale ring : Dummy stave (x14) (who?), All interfaces pièces, Planning. 13
