[Halla_running] [New Logentry] Status Update

Yesterday we got CW beam to the hall and took short Production runs on thick carbon with 2 raster sizes at 65uA and on natural lead/diamond at 50uA. FFB work was done, but was ultimately unsuccessful. Current scans, PITA and IA scans, and BMW were performed. We left off last night trying to get a production run on thick carbon with BMW and parity feedback (no FFB). Plan to examine counting mode data when we get some beam (HallC tuning is happening) and track down possible rates differences in our left and right arms. Then continue with the 65uA/50uA plan on thick carbon and natural lead. 

-Detectors in counting mode
-Collimator temp has been ok
-target temp decreased this morning due to the coolant IN temperature being dropped lower than before (14K now)
-LHRS S0 work yet to be done
-Beam setup to go straight though (not through chicane) at the moment
-Compton background rates going straight through yesterday were 8000
