Un/Under-defined Utilities

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

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

Refrigeration Protection Communication Need similar layouts for DAQ/CCS Fibers and Refrigeration Lines Credit: P. Hascall

Tooling Needed for Integration

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

Bulkhead Plate as Viewed from Camera Tolerance for center bearing?

Cable Wrap and Bulkhead Plate

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)
