------------------------------------------------------------ Date: Sun Oct 21 16:00:52 2001, Shift: 08:00-16:00 Supervisor: KH, with: JC Log book#10 pages 39 - 42 Shift Summary: ------------------------------------------------------------ RHIC achieved beam after 45 hours down at 12:17. We ran for approximately 1 hour when there was B/Y Quench Link Interlock. After that they had numerous problems that prevented the delivery of more beam. Two runs during this time. run trig 1 trig 6 5460 39786 38720 taken after collisions; before fully steered 5461 93845 91203 after they announced fully steered There must have been some problem with beam anyway because although the B/Y ions were approximately 24e9 as usual nowadays, the ZDC rate was never more than 250 even after steering. They realized the discrepancy and were investigating, but did not understand it. Problems for computer experts: pii7 has gotten sick. The symptom was manifested by not being able to run xemacs. Then each terminal would hang when trying to do top or ps ax. I therefore rebooted it (gracefully) and when came up, it gave an error saying it could not bind to NIS Domain. I now cannot log on at the console, but I can through ssh from another machine. But the home directory is not there. Like I said; A problem for the computer experts ------------------------------------------------------------
