On shift: WR & WB 

Log Book #9 Pages 25

Energy: Psi' peak

Beam Current at the beginning of the shift: 17.34mA, 15.65mA at the end  
 

Data taking summary:

run#     Integrated-lum 

7250     ~400 nb^-1 (scaling the luminosity of the last psi' run for the  
                    the number of events on tapes) 
7251       under way 
  

What happened:

17:20 Some problems with the motorized plates(?) that cause a drift
      in the energy. Steve Werkema asked to turn off the jet to bring it 
      back to the right value.  


19:15 Jet on 

Nothing else happened, apart from the instability of the jet that kept us
awake
