10. Un/Under-defined Utilities

11. Utility interfaces are defined in LSE-64 and LSE-65 Still Need:
Utility Topics
Utility interfaces are defined in LSE-64 and LSE-65
Still Need:
Better definition of utility locations in Camera Maintenance Area
Topic is covered by LCR-917
Addition of power for Camera Integration Stand
Topic is covered by LCR-949
Define end-to-end connections of refrigeration protection
See following slides
Define end-to-end connections of refrigeration
Define end-to-end connections of fiber optics
Utilities need to connect to both Camera UT and back of Cable Wrap

12. Updated Staging Area Utilities
Additional Nitrogen Tap
New 220VAC/3-phase/48A per phase for Camera Integration
DAQ/CCS Fiber Optic
Refrigeration Isolation Valve Panel
380VAC/3-phase outside White Room door

13. Refrigeration Protection Communication
Need similar layouts for DAQ/CCS Fibers and Refrigeration Lines

14. Tooling Needed for Integration

15. Mounted to the Integrating Structure
How do we keep the bulkhead plate in position during integration?
Need to align bulkhead plate to top end assy center bearing
Camera needs a restraint for holding in
place during shipping

16. Bulkhead Plate as Viewed from Camera
Tolerance for center bearing?

17. Cable Wrap and Bulkhead Plate

18. T&S provides cart to hold Top End Assy
Tooling Questions
Camera provides lift fixture to move Camera from Integration/Test stand to Top End Assy
T&S provides cart to hold Top End Assy
Camera provides bulkhead plate restraint?
Requirements?
Guiding of Camera into Top End Assy provided by T&S?
Tooling required for this?
If so, must use features already defined in ICD (LSE-18)
