Module Assembly I We plan to assemble the modules in Smith Lab. Severe space constraints (Tour)

Module Assembly II 4 Assembly Stations Source Scan Station Super Box (Tube storage in hallway)

Tube Handling (Baseline) Bring box to door Line up table Slide tubes onto scan table Line up scan table Slide tubes onto assembly station Reverse for complete modules

Tube Handling (Carrier) Super Box with tubes Tube Carrier Fixed to wall or floor In hallway

Tube Handling (Carrier)

Tube Handling (Carrier) Scan Table “J” Carrier Questions: Is this an acceptable solution? Can we do something similar for modules?
