Operator: manouch

Very smooth shift, 200 mA on ABS D2 target. Still running 250 k events lasting 15 minutes each. No WC trips during this shift. No target polarization number yet.

It was discovered that the HV Overright Control for DAQ was left in PERMIT since yesterday (Cosmic runs!). As a result, all runs since last night including run#13933 have been tainted by incorrect charge counting (counting charge while injecting or HV trip). Please see elog # 33205 by Kdow. These runs may be salvageable but require some work. The problem was fixed at around 11:30 in the middle of run 13934.

Good runs since 11:30 this morning are: 13935-41, and 13942-50.

Also for run 13938, I started the next run before elog screen was submited. In the elog record end of run forr 13938 is showns as 13939. Because of this, could not submit another one for run 13939.

Keep running.
