Shift crew: MT,GS,PR,FM Run 594 ended at 1:35 Ecm=3685.6 MeV with an integrated luminosity of 216 nb-1. Deceleration to Ecm=3612 MeV (below the planned 3619 MeV) finished at 2:35. Data taking resumed then, run 596 (rather short) ended with a DYC hang up. Run 597 (~ 114 nb-1) went through 6:00 when the beam was dumped. Between 5 and 6 two quadrants of CCAL were intermittantly on with different gates. Flavio M.
