Our first experiment of the year started right around midnight last night, after extensive tuning. As I understand it, S1151
will confirm the age of the universe. The MWS source performed flawlessly over the weekend. |

Marco and experimenters are busy at it, tuning the DTL. Regarding the source, he is "happy as always!" Well, that makes at least two of us.
After this segment of tuning is complete, then he will move on to setup for the upcoming S1151 run at SEBT2 on Sunday. |

Accelerator development continued this morning. Beam from source was reported to be "good". ICR showed me their long-term Stripchart
of our beam. There is a clear daily correlation of beam intensity with weather. Interesting. Beam idle on FC6 since ~lunchtime. I took the opportunity
to do a little magstab development. The server now runs Konstantin's ser2net patch which fixes |

Beam up as of last evening. Controls performed some network upgrades today, which impacted beam operations. One glitch on our side: OLIS:MB drive bit
was lost. Fault report. Otherwise, all's
right with the world, and Sophia has resumed accelerator development. |

Maintenance Day for OLIS started late yesterday afternoon. Source up at end of the day. See attached Stripchart and in particular how the source (blue
trace is beam at FC6) came back to its nominal state within a reasonable time. Maintenance TBC after lunch.
Later... Hardware maintenance complete. Source HV and source gas tests followed by source startup around 16:30. Next up: magstab development. |

Just in: an active work permit for OLIS maintenance. Underway through tomorrow (Tuesday) evening.

Later... done for today. Source is on for the night. |

Development on Friday; idle over the weekend. Stripchart attached.
Meanwhile, there was a power bump at around 09:30, and the source went out. Restarted OK. |

Beam reserved for continuing accelerator development, but there are some ISAC-I RF phase troubles. However, maintenance was not permitted today... until
just now. Too late for today. |

Beam was used last week for DRAGON commissioning. Successful run, completed yesterday, as reported by Colin this morning.
Milestone: First coasting beam through
new SCC on Thursday, 8-Apr-2010 at ~20:00, using 16O(1+)4+ at 1.5MeV/u from MWS. |

Beam idle overnight. Another night of super-stable beam. If no users today, then we may take it for MRO.
Later... Check out magstab program while we have quiet time. Test outcomes when serial link is opened. Purpose: Improve fault tolerance. Done.
Sophia will take the beam shortly. |

OLIS sprung a water leak last night. Problem was sparking through a coiled cooling line. I replaced the pair of cooling lines and rerouted them
somewhat. Source is up again now. |

Beam idling overnight. Yesterday ICR called me regarding an IOSIOC reboot and consequent fallout. In short, it turned off IOS:MB. Not good. While the
fix was easy enough, it took time to find it, which would translate to downtime during regular delivery. A lesson learned. I just noticed now that the
magnet stability program was out of range and obviously had been since the IOC reboot. I reset the power supply and field. This procedure will need to |
