[3dem] How close can a NMR machine be installed next to a TEM

[Ron Milligan]

Henning,

We had a 600 within 4-5 M and there was no noticeable effect.  The  
field falls off very rapidly in the horizontal direction and is  
extremely constant - more constant and weaker than the earth's  
magnetic field at these distances. And the field is never switched  
off. If the machine does crash then you simply do a minor alignment.   
Buy a "Gauss Maus" and you will find that all sorts of small innocent  
looking lab equipment  are MUCH MUCH more of a problem....

Ron.
