keyword=Switched Compton detector back to PbWO4
During the access, I moved the original PbWO4 crystal (central crystal of
Saclay array) back into position to take Compton photon data. I've
restored its cables (#013 signal, #029 HV) as well. The GSO is now
unconnected and not in the photon beamline.
I will restore the Compton DAQ to its original settings. When we start
taking beam, we'll see if we can get good spectra from the PbWO4; this
should help us identify the problems we've been having getting good GSO
spectra.
