A few lost events were occurring in PDP as the eventfile was getting very large (I think). I started a new event file and the trouble went away.
Unfortunately, the new version of PDP does not permit a new eventfile without a new baseline file. A new eventfile can be created, but it cannot access the orevious basefiles for some reason. We'll be fixing this in the coming days, I hope. Usually we'd start a new event file every shift, but this bug is preventing this. If someone starts a new eventfile, a new basefile and thus new baseline is necessary. DO NOT START NEW EVENTFILES FOR NOW!!!
We stopped beam and microwaves for 5 minutes while I took a new baseline on the top cup.
The material is performing very well, decaying from -90% to -80% over about 12 hours. This is thanks to the low beam current (50nA). I expect the polarization will stay above 60% for the rest of the night, so we should continue production data on this cup. The bottom cup material was annealled a bit too much, so I doubt switching to it tonight will be advantageous to the current material's decay with dose.
Tomorrow we'll be taking a new thermal equilibrium measurement to double check these high polarizations.
