------------------------------------------------------------ Date: Wed Aug 30 00:22:16 2000, Shift: 16:00-24:00 Supervisor: FV, with: FV,KH Log book#5 pages 44 - 48 Shift Summary: ------------------------------------------------------------ Beam during shift from 16.00 to 20.30 where MCR called and announched they would debunch beam and perform studies for about an hour. Beam was dumped at about 21.30. Beam at injection at end of shift MCR needed an access to 12 o'clock. At about 18.00 Phobos requested dump of store, was called for advice. Since beam rate still quite good (75 Y.B.RC clock /sec) we did not recommend this. If we think beam is stil useful we should preferably continue. Two runs collected 2470 356K trigger-1 118K (6) estimated coll. 164K i.e. 42% 2471 282K - 95K estimated coll 137K Both runs 90/5 deg and B polarity. D3D4 at 0 field. During Run 2470 trigger 4 was not operational - The rhic yellow sync had changed about 45 nsec. Corrected before run 2471. Trigger 4 downscaled by 4. T3,T5 were included in data runs. Other accomplishments: a) - The new panels in Brahvo for T3 was tested and certified. - Do not use the T1,T2, MTPC1 and MTPC2 panels until checked. b) The TPC monitoring moved to SuperMonTPC to allow for higher collection rate for all other detectors. T3 monitoring added to SuperMon. Problems: The supermon summary plots for Tof detectors are not very useful e.g. the tof diff dist1 and " Time average" are essentially black due to dot size. ------------------------------------------------------------
