Beyond cryogen fills, I'm wondering if systems can be left without shimming for up to several months, or if it may be wise to keep a sample locked in the magnet for field stability, etc.
Recently energized magnets especially might be prone to faster shim drift, but I wondered how long a stable system can be left before shims are too bad to recover using routine procedures.
Feedback welcome, and I will try to share results with the group (unless requested not to). Thanks.
