List of SLAC items
-Can the rollers/cams be swapped for different support mounts?
-Rubber diaphragm around bar box head; do these still exist? What condition?
-How/where can I safely clamp around the bar box or affix a bracket? – this is so we can build a feature in the holding structure to advance the bar boxes into the mirror boxes…movement in X
-Alignment gauge 22L7484, does this exist? Was this simply used to check roller slots in original structure?
-Any useful leftover parts?
-What type of dimensional variance can be expected between bar boxes, as far as roller location? Did the above gauge cover max expected variance?
-How long can we go without N2 supplied to boxes? - Has been previously discussed but may want to cover again.
-Discuss and understand overpressure valves.
-Do any provisions need to be made for gas supply in the structure?
-What epoxy was used to affix the roller tracks in the bulkheads? Were any fasteners used or just epoxy? Any observed failure?
-Are there any outstanding features on the bar boxes that would cause interference while sliding in X? Anything outside the expected profile (fittings, fasteners, etc.)?
-Dimension sanity/consistency checks – some of these are to verify some dimensions we’ve had to piece together from assumptions:
-box width -box thickness -box head dimensions -cross check roller locations with tape measure – to ensure I’ve placed the support bulkheads correctly.
-Take another good look at the lifting/positioning fixture, in the event we need one…lots of pictures.
