Preliminary PXL support models with assembly fixtures

1 of 4 guide cams MSC_PXL. SLDASM 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

PIT_rail_mount_20 mm. SLDASM removable post allows disconnect from rails , required to • remove rail bonding fixture • connect and disconnect from external test supports

PIT_fixture_assembly. SLDASM (display state: Default_Display. State-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

rail_holder_assembly. SLDASM provides precision placement of the rails for two gluing operations: 1. bonding to PIT 2. match bonding to external rail supports with rails 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 ) numbers give allowable envelope size

grand_master_kin_assembly. SLDASM this assembly (shown with a PXL half) has 3 functions: 1. placement of the kinematic mounts for bonding to the PST 2. support of the kinematic mounts for tests of detector insertion mechanism 3. 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

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
