Accelerator Update - June 9-June 11
D0 came out of access at 8:31 AM.
The TeV front end crashed. A controls expert rebooted the computer at 3:12 PM.
At 10:38 PM, a Main Injector (MI) expert began conducting studies.
At 1:41 AM, Operations terminated store 2667. D0 accessed their collision hall.
D0 came out of access at 5:30 AM.
At 6:15 AM, TeV experts began a period of beam maintenance focusing on the sextupole magnets.
Operations put the TeV through a dry squeeze at 1:24 PM and then put the TeV into shot setup at 1:51 PM.
D0 reported having some trouble with their toroid magnet at 2:12 PM. An expert had the toroid working normally forty minutes later.
At 3:30 PM, Operations established store 2671 with an initial luminosity of 28.04E30.
Linac techs completed their work on LRF2 at 4:57 AM. Pbar resumed stacking and MiniBooNE resumed taking beam.
The Collider Detector Facility (CDF) called complaining about the Tune of the beam. Operators made a horizontal change, which resolved the problem.
Wednesday June 11
Operations terminated store 2671 at 6:13 AM. TeV experts began a beam maintenance period.
A Switchyard expert began a study period at 6:23 AM. The expert reported getting beam to TeV sector F49 on the first pulse. This sector is the point where beam leaves the TeV tunnel and enters the Switchyard transfer lines.
