Dan,

We are in the process on getting a new NMR and I noticed in the "site 
preparation" from Varian that they strongly recommend not having 
carpet.  Static buildup apparently can have adverse effects on the 
homogeneity of the magnetic field.  The extent of the effect will depend on 
how much shielding your magnet has.  It might not hurt to run the carpet 
request by your NMR vendor.
