On Shift: XF and GG

   Continue to take data at Ecm = 3620 MeV for etac prime.

   Smooth shift. Totally we have 1088 /nb at this energy point so far.

RUN  Luminosity
902    145.6 /nb   (inherited from last shift)
903    146.4 /nb
904    150.4 /nb  
905    under way 

   Beam current dropped from 18mA to 14mA, gas density was changed
several times to keep the luminosity between 1.8-2.0E31.

   By looking at online monitor, we saw that straw HV tripped at 6:20am
and tripped again at 6:40am (RUN 904), reset straw HV twice. 

   Argon Mix for the straws: the bottles probably should be swapped in
the early afternoon of today. Instructions are on the gas check list
(12/7, 4:50am).

   Cheers.
