Ecm = 3525.25 MeV  (1P1 peak?)

Run 5771  nb^-1  

initial Ibeam  : 18.19 mA       final Ibeam  : 10.76  mA 

average instant. luminosity :  2.2 10^31 cm^-2 s^-1 
Sigma Ecm 300-330 KeV 

Comments:

17:30 Steve Werkema calls. A quadrupole has been found with wrong setting.
      This was likely the cause of the beam problems occurred so far.
      He will try to fix the problem.

17:52 Steve says to turn on very very slowly the jet target while he moves
      the bean energy to 3526.25 MeV, since it has dropped to 3525.67 MeV.

18:56 Ecm is now 3525.25 MeV, sigma Ecm = 310 KeV, Ibeam = 12.66 mA. 
      We start run 5771 with jet density = 3.9 x 10^14 cm^-3 and 
      lumin = 2.2 x 10^31 cm^-2 s^-1.

Unclugging performed 3 times. No DAQ hungs.

22:00 end of run and stack. MCR will investigate the quadrupole problem.
      Thanks to MO and MN for helping doing the end of stack procedure.

Buonanotte,
