All,
For as long as I can remember, I'd been told that the way to cool off your
cryoprobe was to set the improve vacuum duration such that it pumps overnight,
heat the probe up to help bake off impurities, and then burn it in with an
appropriate pulse sequence the next morning when it is cold. As I was cooling
one down today, I actually thought about it and realized heating the probe
is not going to do anything as the coil is insulated from the sample portion
so it won't get warmed by turning up the temperature. So, is turning the
sample temperature up futile, or do I not understand the process correctly?
Thanks,
John
