At 5:00 this morning, after a lengthy battle with cancer, Mike passed from this life to his eternal reward. He has left us a great legacy. May he rest
in peace. |

Tue Jul 7 15:43:19 2009, Damien Gallop, Routine, General, ISIS emittance rig tests this morning
|
Keerthi and I were front and centre doing ISIS emittance rig testing this morning. He ran it, and I tried to find ways to run the data in Matlab afterwards.
Main limitation up there at the ISIS Console is lack of any ssh-enabled terminals. Keerthi's wireless laptop is okay, but this stuff pushes the poor little
thing to the edge. Plus, there were some X display issues on it. He has Matlab installed locally, but it takes a bit of a rocket scientist to run it, and |

IRIS beam delivery is completed with extra 3 days of beam providing to them.
18O2 and 40Ar+2 were delivered with few attenuators i place. |

Thu Oct 29 09:42:23 2009, Damien Gallop, , , IOSIOC work in progress
|
Yesterday there was an IOSIOC reboot for a purpose. It was an opportunity to demonstrate to Controls that IOSIOC reboots materially affect the IOS section.
Controls responded to an ICR fault report on it, and have not reported back to ICR so far. The source was off overnight and remains off now. I have informed
ICR that if nothing happens this morning, I will restart the source after lunch. |

Wed Mar 9 11:09:02 2011, Keerthi Jayamanna, , , IOS:SSW failed
|
| IOS:SSW failed unexpectedly. No reason found. Came back on easily. |

Fri Mar 12 11:33:09 2010, Keerthi, , , IOS:IG!
|
| IOS:IG1 is faulty. Need to replac it during next earliest window. |

Fri Feb 18 11:43:32 2011, Keerthi Jayamanna, , , IOS: EE Status
|
| IOS:EE found damaged. It has been replaced with IOS:SSEE-Michael B. |

Wed Jan 22 10:34:58 2014, Raymond Dubé, , , IN-line 100K for IOS:YCB1A removed
|
Last January 17th 2014 we removed an in-line resistor (100K 10W) from IOS:YCB1A because we do not think that it is needed.

| Welcome to 2010. Shutdown is underway across the site, while beam development is going on at OLIS. |

| Controls group may need some assistance from OLIS group in order to trouble shoot the problem. |

Mon Jun 22 16:00:04 2009, Damien Gallop, Routine, General, Emittance thoughts and other matters 7x
|
An emittance scan of the 16O7+ beam follows. Also, a stripchart of the same beam on FC6 overnight. Keerthi did some studies over the weekend. He found
that the characteristics of the amplifiers behind FC6 and the emittance rig cup differ significantly. That's disconcerting. We did a visual this morning,
and confirmed that the amplifiers are identical VME modules in the same crate. He believes it's a scaling thing. We will test again with a current source |

Mon Jun 8 09:31:39 2009, Damien Gallop, Routine, General, Emittance scan of 18O beam from MWS
|
The TIGRESS run ended this morning. Supernanogan Development begins now for two weeks. Begin an 18O1+ emittance scan and also take some fast FC6 current
measurements before we switch over. |

Wed Feb 22 21:46:27 2017, Keerthi Jayamanna, , , Elog is working now

| Elog is now functioning. We can start entering notes |

Tue Jun 23 10:33:43 2009, Damien Gallop, Routine, General, Effects of RF on charge state
|
Today is the last day of this set of Supernanogan Development. The source ran at 16KV overnight, in anticipation of 16O2+ delivery later today. I expected
more bias sparking, but it appears that it sparked off only once. So I will condition at a higher bias later today. Meanwhile, the operators reported touching
up the tune with the magnet and the RF. Perhaps we are seeing some temperature effect on the source, so I will be looking at effects of RF on 16O7+ for |

| Both EE and SSEE problems were solved. They are working OK now. |

| Cusp source water cooling (#4) interlick does not work. |

Tue Mar 29 15:32:08 2011, Damien Gallop, , , Controls and Panel MRO
|
Controls is working on an interlock issue. Electrical panel MCC-X maintenance is planned for tomorrow afternoon.
Loaned a Horiba SEC-7320 flow controller to Mel. This unit belongs to Friedhelm. |

Tue Jun 30 17:39:13 2009, Damien Gallop, Routine, General, Compare 16O2+ beam from start of run to today 6x
|
There seemed to be some small change to the beam over the week of TACTIC running. I would like to poke around a bit. The emittance plots suggest some
vertical movement at least. The two plots are the before (emittance)
and after (emittance). |
|
Thu Jun 18 09:38:52 2009, Damien Gallop, Routine, General, Check Supernanogan beam after IOC reboot yesterday 15x
|
As mentioned before, IOSIOC was rebooted yesterday afternoon to unfreeze the emittance rig panel. It cost us our tune, which unfortunately wasn't saved
very well. Lesson learned: Save often. I will run a mass scan now and check the mass correlations calibration. Then I will pick up with some 16On+ emittance
scans. Keerthi was here until late last night working with the beam also. He will have some results for sure. |
