Shift Crew: F. Benmokhtar, H. Fenker, M. Khandaker18:00 Sweeping the hall is done 18:10 Moved the HMS back to 17.96 deg. 18:55 Production mode started. All is smooth. Few warnings of roc 14 and 13, but they didn't crash at all. We took 3 long runs.
21:50 MCC took beam to investigate soem vaccum problems in the north linac. He thinks that Hall C beam is causing it and this is disturbing the other two halls.
23:15 MCC is still investigating the orgin of the vaccum problems in the
north linac. He could go to 60 uA, so I called them to say we can take this 60 uA. BUT they say that they found out that these vaccum trips are not really dUE to the beam current they do exist at high or low current and they want tO investigate more.
00:00 MCC called, they arestll working on the beam, they said it will take them 15 more minutes. They wil ltry to put us off, when the other halls are on.
