Test Area
- Notes:
- Area in the test lab is 20'6" x 25'9", currently filled with coils and coil parts.
- Bob Bennett is Test Lab "space czar."
- Wayne is designing overall layout.
- Will use SRF storage area for large power supply (6' x 5', 5' H, 5000 lbs) and switch (QWeak area unavailable).
- Must maintain clear areas around racks and power supply, and cannot block pedestrian walkways.
- Platform is 172" x 160", cryo can will sit on top.
- Platform must be removed to swap coils, and all connections to it must be broken.
- Area has two 25T cranes, but need both (and strongback) to lift heaviest pieces (up to 45 tons).
- Only a few dual-crane lifts needed.
- Need come-alongs and anchors to move yokes and coils along rails.
- Some areas will need to be roped off due to high B fields (5 G for pacemakers; other limits 60 G 8-hr body, 600 G 8-hr limb).
- May need to remove some fences.
- Magnet forces: 5 kG == 1 Atm, scales as square of B field.
- When done, may leave infrastructure in place for magnet tests for other halls.
- Coil center located 1/3 of the way along the long axis of our test area.
- When saturated low field regions extend fairly uniformly around coil center in all directions. When not saturated low field regions extend out mainly along coil axis.
