Two beam storage was made during the shift. The first one was cogged at 8:15. Blue/Yellow=27/33 ZDC=600. The beam was dumped at 13:15 after one hour gap cleaning with low rate. The second beam was cogged at 14:25 with the ZDC rate of 2700. 5 min. later the rate went down to 2200 and 10min. later to 1700. T3 currents at the beginning were 75, 65, 60 micro amps. 20min. later Yellow ring lost 30% of its beam suddenly and the rate went down to 900. After that the beam became more or less stable. 2. run trigger 6 Setting 5939 170K FS 8deg-2/3A MRS same sa before 5940 32K FS 8deg-1/8A but wrong D3,D4 current setup. 5941 15K same as above 5942 TPC Pedestal run 5943 DVM 5944 pedestal run 5945 106K FS 8deg-1/8A with right current for D3,D4.
