We are experiencing a new wave (so to speak) of 10 Hz building vibration
issues with our 600/51 magnet. The magnet's TMC legs afford only
minimal attentuation for frequencies that low.
One contemplated solution that seems easier than getting Physical
Plant to fix the source of the vibrations is to relocate the magnet
about 25 feet to the south on a much quieter part of the floor.
So, the question is: do any of you have experience with the live-move of
magnets as large as a 600?
I've long been an advocate and participant in moving smaller live magnets,
We recently hauled our 500 out-the-door-and-down-the-hall to another room
with no problems. Lineshape in the new room was better than ever with
just basic reworking of the RT shims. Then, of course, there was the time
when the cowboys at GE trucked a live 500 to Asilomar...
The 600 is a lot bigger and more daunting, but the trajectory seems simple
enough --a straight slide across a smooth, level floor in a room with high
ceilings.
Possible responses:
[ ] you've got to be out of your mind
[ ] do-able with the right preparation & equipment
[ ] piece of cake... just do it!
[ ] OK, but don't tell the Office of Risk Assessment
[ ] we've always wanted to visualize a 90-flip in the laboratory frame
