keyword=Owl shift summary
Hall was in controlled access until 1:08
Setup for H elastic kinematics Point 1 0.5577 GeV/c
Started with optics.
good runs are 1757 - 1759 (before the raster was not working, also the prescaler ps3 was too high). At end lost beam.
Switched to LH2 and started run 1760 at 2:37. Take data with 8uA since trigger rate is only 1k. Deadtime is about 16%.
After 2 hours the file split, but we stopped and started a new run.
The split file is very short.
6:45 changed to kin point 2 (0.5467 GeV/c). The trigger rate was now more than 3 k, reduced beam to 4 uA which gives 24% dead time and 1.9 k rate
started run 1763
