Keeping an eye on the polarization of the target when it should be stable is part of the TO's responsibilities. One easy way to check that the target polarization is working well is to look at the lock-in peak heights. The TO should make a log entry of these peaks once per shift or any time they change significantly.

If you are ramping up at target, these peaks will be steadily increasing in height. You want to watch for a sudden drop. If this happens, call an expert.
