keyword=Owl shift summary
We started the shift after the Moller commissioning. Getting the beam
back to the previous setting took some time, and the quality was poor
(very high Compton rates, frequent ion chamber trips). We could not do
any work on the Compton.
We did some BPM studies (see related entry). BMPs are still saturating
and need some expert look.
We shot some beam on solid targets to see backgrounds on the calorimeter
(PMT anode currents in particular). At first look, we don't see any
significant values, but since the target is warm we couldn't run any high
beam current.
At around 5:30 we turned the beam over to MCC for them to perform some
multiharp scans. We'll request controlled access as soon as they are
finished.
