Hi All,
I'm seeking the collective wisdom regarding a site planning pickle.
We're replacing our old 400 MHz magnet/console later this summer. The grant
also included a full helium recovery system with three medium pressure storage
tanks that we're in the midst of installing. I think it was assumed the new
magnet would be installed before the recovery system, and that didn't happen.
The old magnet hasn't been decommissioned yet and it's unshielded. The 5 gauss
line extends ~7ft from the magnet, and the plan has one of the tanks crossing
it by a full foot. Each tank is 8.5ft ht, 3ft dm, magnetically susceptible
(steel?), and ~400 lbs. We have to permanently bolt down all three next week.
I can rearrange the plan, but it would be a tragedy for the lab layout, and
I'd never hear the end of it.
Does it seem like an acceptable risk to put that much metal inside the stray
field?
My building manager thinks we could slide the magnet a foot or two out of the
way with johnson bars. I've only ever heard the direst of warnings about
trying to move a magnet, and I'm skeptical we could even pull it off if
we tried.
Kind regards,
Luke
