1 of 4 guide cams
1 of 4 carriage rails
1 of 8 rail bond pads
display state: disappear fixtures and ist
3 kinematic mounts with bond pads
display state: disappear fixtures

PXL kinematic mount bond pad on outside of PST
IST support frame

4. PIT_rail_mount_20mm.SLDASM
removable post allows disconnect from rails , required to
remove rail bonding fixture
connect and disconnect from external test supports

5. PIT_fixture_assembly.SLDASM (display state: Default_DisplayState-1)
grand_master_kin_assembly.SLDASM
external rail supports for testing insertion of detector and engagement with kinematic mounts before PIT exists
rail_holder_assembly.SLDASM
end supports
position end flanges for bonding to PIT and
position rail_holder_assembly.SLDASM
note: the external rail support and PIT don’t occur together as shown here. It is either one or the other supporting the rails

6. rail_holder_assembly.SLDASM
provides precision placement of the rails for two gluing operations:
bonding to PIT
match bonding to external rail supports
precision drivers:
glue bond gap to PIT ( 50 m )
avoid binding ( 25 m or 200 m, depends on carriage design)
proper engagement with kinematic mounts ( 400 m )
detector collision avoidance ( 250 m )
with rails
numbers give allowable envelope size

7. grand_master_kin_assembly.SLDASM
this assembly (shown with a PXL half) has 3 functions:
placement of the kinematic mounts for bonding to the PST
support of the kinematic mounts for tests of detector insertion mechanism
Support of detector halves in the Coordinate Measuring machine for spatial mapping operation. Position of the kinematic mounts should accurately match the locations in the PST

9. MSC.SLDASM
used latest model from Eric and Jason with following changes:
increased length of PIT
added a flange at the original PIT ending
drilled some holes for the rail mounts and kinematic mounts
cleaned up some coordinate frame alignments
