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 (Just started with Kinematics 4F).



02:17  The CODA for HRS-L spectrometer crashed. We stopped both

       runs (HRS-L and BB), restarted the CODA for HRS-L and

       started new runs. 

	   

04:00  We have changed the momentum of the HRS-L spectrometer 

       to the 0.6GeV/c and started taking data for kinematics

       4A.	  



04:12  BB Deadtime monitor started showing negative deadtime (-70%).

       We stopped both runs (#20717, #2209), killed BB CODA, 

       started new coda and started new runs. Dead time was still 

       negative, but after a while, it became positive again. We

       have decided to leave  runs (#20718 and #2210) running, 

       because in online analysis all data seemed to be fine, except

       for the deadtime, which was negative (-15%).

       

07:02  MCC took our beem away and they asked us to move the target to 

       empty.

	   

07:15  We are in Controlled Access
