Present situation

• R_Light_01_01 (R) ATL-CSC-01-00-00
• primary numbers coming from plans
• Reference allow cross check and debugging with
  Alignment software
• R_Light_01_01_EGG(R')
• egg shape (7.5 mm in vertical direction, except
  BEE)

• R_Light_01_01_EGG_RNDM (R) ATL-CSC-01-01-00
• egg shape (7.5 mm in vertical direction) overest
  imated (4mm)
• shifts 1mm in 3 space directions underestimat
  ed (2 to 4 mm)
• tilts 1mrd in 3 space directions underestimat
  ed (2 to 4 mm)

all chambers barrel end cap are moved

Missing elements

• Saddle
• Small big wheel supports
• MDT barrel supports
• CSC supports
• ID patch panels
• Access platforms
• Platforms sector 13
• Services (cable tray...)
• Tomograph data
• ....

• Black already in primary numbers (AMDB) but not
  in GeoModel/G4
• Red not yet implemented anywhere

Primary numbers

• Primary numbers coming from plans
• active part MDT,RPC,TGC,CSC
• dead part coils, feet, cryostat ,..
• 50 000 parameters
• No clashes only one way to debug PERSINT

• AMDB description
• D-line objects Dimensions
• P-line objects Positioning
• H-line Cuts out
• A-line alignment correction (x,y,z,,qxqy,qz)
• B-line MDT deformations (8 parameters)
• never been tested

7
Oracle(1)

• Old way to update Oracle DB
• Active part
• complicated chain to create SQL files
• no maintenance possible
• primary numbers vs Oracle checked (AmdcOracle
  Svc)
• position deduced from primary number vs GeoModel
  checked (AmdcMGM)
• Dead part
• complicated chain, no maintenance possible,
  update very difficult
• no way to compare easily primary numbers and
  Oracle parameters due the absence of BREP'S
  Boolean in GeoModel/G4
• coil, feet, ... done long time ago, parameters no
  coming from primary numbers gt CLASHES

8
Oracle(2)

• New way to update Oracle DB
• Active part New chain, clean, from primary
  numbers to SQL files
• NTU Athena / Saclay share the job
• SQL files are easier to update Oracle DB
• CSC cosmic set-up do in that way
• need to validate with r_01_01 the new path
• need to update primary numbers to Oracle
• Dead part
• primary numbers already in Oracle

9
GeoModel

• New way to update GeoModel
• Dead part
• Source-to-source translator written to
  automatically go from XML to C
• prototype ok
• update on BREP'S G4 in place
• Work to be done to validate the new path
• stopper need to debug GeoModel for BREP'S
• need to validate G4 new volumes
• read at initialisation phase primary numbers from
  oracle DB
• validation for an already existing volume (ex.
  Voussoirs) with muons
• update all dead matters parameters
• full validation
