Mechanical GSEMechanical GSE

1. Frame: connecting to Grid bosses and Frame Support Fixture

2. Worm Gear Reducers: connect to Frame and Frame Support Fixture. 360 degree rotation.

3. Frame Support Fixture: connects to floor and Frame via Worm Gear Reducers

4. TKR Unit Lift Fixture: maintains stability for Unit as it is connected to Grid.

5. CAL Unit Lift Fixture: maintains stability for Unit as it is connected to Grid.

6. CAL Container: connects to Frame and contains nitrogen flow to CAL.

7. Overhead Crane: 5 ton overhead crane for lowering subsystems and lifting integrated LAT

8. ACD Lift Fixture: connects to ACD and crane rigging.

9. Metrology Fixtures: strategic location of laser tracker balls for measurement of fiducial points

10.Fixtures for integrated LAT testing: SLAC test beam, shipping, thermal vacuum, vibration table
