keyword=New Cavity phases since cavity cables were swapped
Pavel switched the electronics for the cavity monitors so that the upstream
electronics (cav2) is now connected to the cavity which is physically the
downstream cavity and the downstream electronics (cav3) is now connected to the
cavity which is upstream. The new phases are shown below. Things aren't
perfect, but perhaps they are good enough for now to identify whether the
pickup problem we see is from the cavity or the cavity electronics.
I was changing the cavity phases a lot during HAPPEX runs 6475-6479. I took
spectrometer runs 3076-3079 to look at the quality of the phase values.
