6/9/00 Day Shift Summary: (Log Book: #8, p.69-71) On shift: SS,MG Data Type: 1p1 bkg (Ecm=3529 MeV) Beam current at start: ~32 mA . Beam current at end: 26 mA . Typical Luminosity: 2.4 x 10^31 cm^-2s^-1 Run: 5792 (341.2 nb-1) inherited 5793 (335.4nb-1) 5794 in progress Typical SigmaP--~1.5 MeV Comments: Wide beam and high loss rate... 17:50--Loss rate=~1.2->contacted Giulio and this was reduced to ~0.8 20:10--Loss rate shot up to 2.2 (after nozzle unclog?)->Martin Hu worked on getting it back down to under 1.0 22:55--sigmaP drifted up to ~1.8MeV->Martin got it back down to 1.4 3 DAQ hangs 2 nozzle unclogs Have a good night...
