Dear all,
Thank you for your responses. According to everyone's feedback, vibrations
from construction work 100 ft away won't affect NMR magnets.
Thank you,
Thomas

Thomas,
You could check for vibrations like GE NMR engineers did; set a cup of coffee
on the floor and look for ripples. I concur with Gary, but the gross vibration
test will put your mind at ease.

Dear all,
We have a water leak outside the building housing three NMR magnets, and our
university Facility Services have to demolish concrete slabs (stairs) to
fix the leak. They used an excavator breaker to break part of the concrete,
creating a vibration in the building. The construction site is about 80ft
and 100 ft from two magnets with ANTIVIBRATIONFEET TYP A STAND and about 120
ft from a 700 MHz Ascend magnet. Do we have to worry about the vibration
messing up the magnets (we are not worried about experiments currently running)?
Thank you.
