On Shift: RC, MA Some problems during run: - Constant luminosity mode failure ( ACNET connection failed) Started again and was OK. - Lum_mon data acquisition failed. Restart PC but still no data. Started again with the help of XF. - During run 845 ( at 1:00 pm) the beam shown a strong instability (loss rate 15 mA/h!) for less than a minute. We lost a few mA (from 59mA to 56mA). DAQ paused. Jet target off. The beam drifted at a value p_beam=6235 MeV/c (3 MeV/c higher what we need). MCR is still investigating to understand beam instability and to set the correct value of p_beam. Integrated luminosity ===================== RUN 843 212 nb-1 RUN 844 210 nb-1 RUN 845 36 nb-1 At present ( 6:15 pm) work on the beam still in progress ( no data taking). Happy Thanksgiving Roberto
