Entry number 186281

Shift start in middle of run 1035

Run 1035 Sieve right arm single C

Run 1036 Sieve right arm optics target



Switch to LH2 target. Had problems detail in separate elog.

Lost one hour of beam time.



Limited to about 60uA on LH2 to keep ESR flow to Hall A < 12



Run 1037 Sieve right arm 318K events



Steffen decides to skip the LH2 Right arm open and sieve Left arm

to see if something can be done with target to allow more

beam current.



Run 1038 LH2 production at 0% delta with FPP doors at 9+3" . 1.1M events.



Run 1039 LH2 production at 0% delta with FPP doors at 6+3" . 5M events.



Find that the efficiency dropped when conetest is included when

going with thicker doors.



Run 1040 LH2 production at 0% delta with FPP doors at 6+3" . 5M events.



Run 1041 LH2 production at 0% delta with FPP doors at 6+3" . 2.8M events. Ended run early becuase Alex changed the delays which modified

the trigger timing and we had no T5 triggers. Reloaded trigger



Run 1042 LH2 production at 0% delta with FPP doors at 6+3" . 5M events.



Run 1043 LH2 production at 0% delta with FPP doors at 6+3" . 5M events.



Run 1044 LH2 production at 0% delta with FPP doors at 6+3" . 5M events.



Run 1045 LH2 production at 0% delta with FPP doors at 6+3" . 5M events.



Run 1046 LH2 production at 0% delta with FPP doors at 6+3" . 5M events. During run reset right arm magnet IOC so EPICS values

will be wrong during run.
