Dear AMMRL;
Full rebuild of the magnet in July 2015.
Measured 4.882 Hz/Hr. May 16, 2016.
Plotted the lockfreq vs date from before we reenergized it till now. Attached.
What could have caused such a sudden decrease in lockfreq? I'm still gathering data such as boiloff logs and a new drift rate which I'll update later.
Thanks,
