Shift summary 23-11 from 0-8 am.
On shift Mara Martini, Sheng Jin, and all the night the precious 
collaboration of Keith.

Beam momentum 4067.567 MeV/c 
Ecm 3097.565 MeV/c.
We started to take data at the beginning of the shift after a series of
DAQ resets.
The thresholds of the NUT (NeUtral Trigger) were changed by Sheng, 
and we prescaled by a factor of 10 the phi-phi trigger as well as the 
Etot (software prescale). 
We were running at 2.8x10^30cm-2s-1 during Run 823.

The tagger program showed a small number of events with respect the one 
expected, ie a cross section of 2nb instead of 18nb (from E760).

At 3:30 we call Paul who decelerated to Ecm = 3096.821 MeV/cm.
A little bit below the peak...
The cross section is around 11nb.

Run 824 has 29nb-1. 

We stopped because the acquisition hung. 
Now (8:15) we are running since 11 minutes without problem (Run 828).
We have called George.

Detector performances: several plots are glued on the logbook.

Cheers
