Modules drawings

• 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 !!!

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

Prototype

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…

container

Length : 8900 mm !!!

Dummy stave -> Final stave

Length : 7000 mm (2750+1500+2750)

Assembly scenario

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.
