RHIC started filling at 2200. Since then we had good beam. 2. Run4831 with trigger1=145K, with T3 Anode1 tripping. Run4831 with trigger1=80K, with troubled T3,T4,T5. Magnet setting MRS 4A, FS 1/5 A 3. HV mainframe 4 and 5 has been bypassed by remote control. HV default settings for these mainframes were checked and control was set to local control during an access to IR as an emergency measure. The mainframe 4 and 5 should not be recycled until the next access. T3 Anode-1 and Cathode-1 could not be turned on. Ramiro suspects there is a short in Anode-1 and Cathode-1 of T3. 4. Run 4831 has pulser Trigger 7, scaled down by 70, with with drift velocity monitor pulser so that DVM is now integrated into data runs. Remember that Mainframe 4 and 5 should not be cycled until the next access. ------------------------------------------------------------
