Owl shift summary: Miha Mihovilovic (SL), Huan Yao (TO)

===================================================================



EVENTS

------

00:00  Start of the OWL shift. We are in production mode

	   and are taking 3He data (Kinematics 4C).

	   

01:42  Changed the momentum of the HRS-L spectrometer to

       0.6 GeV (Moved to kinematics 4A.) and moved the target 

       to Nitrogen. The pressure in the target was 114psi.

       

02:27  We moved the target back to the 3He target.



02:28  There is missing a End-of-run-file for the HRS-L

	   run #20674.

	   

04:18  There was a trip in Big-Bites second wire chamber.

       The channel L14.6 tripped. We have stopped both

       runs (#2146, #20676), waited a few minutes and than 

       proceeded with production runs.

       

05:15  We made a NMR measuremend of the target. The polarization

       is 62.47%

       

08:00  At 07:55 MCC started giving us only 0.5 uA beam. I have

       called them and asked why? They had no good explanation,

       and promised to give us back 15 uA.
