Shift Summary 4/15/2000 Evening: Beam at start: 28 mA; Beam at end: 19.8 mA ; Typical Lumin. (2.0-2.5) x 10^31 Data type: chi0 background (Ecm = 3385) Runs 5491 (185.0 nb-1) (inherited) 5492 (224.2 nb-1) 5493 (222.4 nb-1) 5494 in progress Shifters: DB, WB Log Book 7 Pages 60-64 Summary: Data taking at Ecm = 3385. Approximately 1.5 hours into the shift mainframe 2 went off. We stopped the run (5491), power-cycled the mainframe and turned it on again. After that it worked fine. We ran the gas jet in regulating mode most of the time. Still we had to adjust the density a couple of times as it was drifting upwards resulting in too high a rate. Other than that: few DAQ hangs successfully taken care of with RESET and two acnet alarms (fixed by MCR). Diego and Wander
