On shift : RC, DB ( + GG) LOGBOOK #7, pag. 34-37 We continued the run at the chi_0 background (3470 MeV) with a constant luminosity of about 2 * 10^31 cm^(-2)s^(-1). At the end of the shift the beam was dumped. Beam stable (initial current 17.3 mA, final current 11.5 mA). Jet quite unstable. Smooth shift. We warm up the nozzle 4 times to unclog it. 7 DAQ hangs, reset works OK for all cases. LUMINOSITY SUMMARY RUN 5461 Integrated Luminosity: 308.9 nb^(-1) (inherited) 5462 Integrated luminosity: 280.9 nb^(-1) 5463 Integrated Luminosity: 273.1 nb^(-1) Total integrated luminosity for this run 862.9 nb^(-1) Total integrated luminosity for this energy 2557.8 nb^(-1) ( more than 1.7 pb^(-1)/day ) Roberto and Diego
