Tracker Mock-up Engineering DevelopmentTracker Mock-up Engineering Development
• CMM Program established from Tower Mock-up model
Developed in Bay area and at INFN
• Experience gained from Mock-up
Tower to Grid simulator installation
Alignment of Eccentric cones
Testing of the CMM program
• Differences between Mock-up model and E.M. (Flight like) model
Corner Flexures are non flight like (older rev.)
Does not contain corner brackets or flight like reflector ball nests

Tower Alignment SummaryTower Alignment Summary
• Measurements at INFN
– Used their CMM which runs PC-DMIS
– Created measurement scripts for automated measurements
– Derived CS which puts tower in optimized position, i.e. Z-axis vertical wrt gravity, X, Y symmetrical to actual shape
– Determined coordinates of flexure conicals in tower CS
– Comparing actuals vs design yields dial-in settings for cones
– Applied settings, mounted tower to base
– Cross-checks good to 500 µm (TBs too small and loose)
• Planned measurements at SLAC
– Verify procedure by independently creating equivalent measurement routine on our Leitz PMM using Quindos
– Repeat measurement / alignment cycle at least three times

+X, +y designates the stud on the + y side of the flexure which is on located on the +X side wall.
For all side flexures, the side flexure identifier is capitalized, while the side flexure conical(stud) is in lower case.

Installation Procedure (Static test) - INFNInstallation Procedure (Static test) - INFN
• Refer to section 2.1 of LAT-DS-0425-01
• Installed Grid simulator with no Aligning– Performed on Tower Mock-up– requires no Aligning tools– Adjusting tools required
• Preset three inner and outer cones to the concentric position
For three reference locationsUsed to locate the position of TowerAlign slots on both cones
• Remaining cones are to be “Dithered”Process in which cones seat to their required position

Presetting ProcedurePresetting Procedure
Refer to section 6.1 of LAT-DS-04245
Section 6.1.9: determine α by using Matlab program “angtool”
Setting α, “inner to outer cone angle”

Tower C.S +Z
Struc C.S +Z
Tower C.S +Z
Define a coordinate systembased on the location of
Top and Bottom Tray Hardware. Then move it so it is centered on the shape and size of the
Sidewalls
Calculate Flexure Point offsets from nominal
and check against available travel
Set Eccentric Cone rotation,
then mount Grid Simulator
and fit with shims.
Determine β for each reference locationLAT-PS-04245: Section 2.3
