Partial disassembly of DB1 optics today. Shielding of insulators is definitely working and indicated for unshielded insulators. Discussion of possibilities
in progress. Wiring looks good, but one Kapton wire snapped at the connector upon disassembly (no force required). |

Microwave source is up and running.
Supernanogan: grounding rod is stuck, RF generator does not clear the interlocks (controls?)
LEBT: FC3 air leak, in is out, out is in |

20Ne1+ set up from the MWS and handed over to Sophia & Marco for accelerator recommissioning. Strip to 5+ at M:5. First day of beam. Happy St. Patrick's
Day.
Later... a Stripchart of beam today: baby-blue trace is FC6. Also, here are screenshots of the source. |

Beam is on standby. Target snapshot
in IOPS elog. Over the last little while...
* IOS:IG1 repaired last evening. IOS vented to Ar, flowing for duration of repair. Standard Varian filament repair kit used with Dimo's instructions. |

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 |

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. |

| 16O1+ beam requested yesterday. Source switched over and beam ready by evening. Nice overnight Stripchart, attached. Sophia has the beam now. |

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. |

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 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. |

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. |

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

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