Dear AMMRL:
Would a temperature fluctuation of 0.1-0.2 degree be expected to cause a
visible change in shimming?
One of my users is running experiments at 323K and has complained that the
shimming (i.e. lineshape) degrades over several hours. He attributes this
to poor temperature stability. I had considered +/- 0.1 to be good for
temperature control, especially since the temperature reading is only to the
tenth of a degree, but would appreciate any insight from the group.
Thanks,
Stephanie
