Delivery to S1151 went quietly overnight for their last few hours. The run ended at ~08:30 as scheduled. Marco and ICR did some EOB checks. Also, a quick
EOB emittance scan is attached. There were problems
with the beam tune save files, since resolved. Among the last ones are 100430_0918.snapiossebt2 (missing SEBT optics) and 100429_2023.snapiossebt2. |

| 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. |

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. |

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 |

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. |

| Beam idle overnight. Source conditioned and changed a bit. Slight tweaking required to bring it back to stable. |

Source drifted overnight. Operators made a slight correction to silence an alarm. I have tweaked this up. Shown below are before and after. Marco believes
present beam is unstable. I will see if I can tweak up the intensity, and perhaps that will satisfy all requirements.
Later... ~13:00 this is just about as good as it gets. Stripchart of the last couple of hours plus current excellent source parameters appended |

Beam used sporadically over the weekend. Note temperature response in beam. A power bump occurred at about 10:00, knocking out OLIS. It was challenging
to come back to where it was before. |

MCIS finished xenon development. MCIS is off and isolation valve is shut.
A new oxygen gas line is installed to microwave ion source via a hand valve neat PE.
Hand valve is tuned as a small leak so that the plasma can run with all other gas valves are shut.

Delivery to TIGRESS ended this morning as scheduled. ICR took nice emittance
scans and is completing a target snapshot now. Canister still at -22"Hg and MCIS at 7.3e-8 Torr.
Chance to snap some wirescans. Attached. |
