A lot has happened since the last entry. The source blinked out at some point. Cause cited was a PE short. Actions were taken, to be detailed later.
Source was re-lit. Beam on FC6 was unstable yet promising overnight last night. In the wee hours it blinked out again and is out presently. Remotely checked
vital signs. The only thing that appears to require immediate intervention is the source gas line, which looks very closed. ICR assisted with a check on |

After EOB activities from 15N4+ run that ended this morning, we have begun preparations to switch over the ion sources. Turbos off just after 11:00.
We have Mg source material ready. We will be using the MWS ion source. Due to the requirement to run the source at 53kV, we will also remove the Supernanogan
cart from the cage as a sparking precaution. |

On Saturday we opened the MWS and set it up for Mg operation. Everything went well. We are using the pair of half-moon Mg metal plates together with
a thin Mg foil liner inside a bottomless quartz liner. Tune setup for HEBT/SEBT operation set up yesterday. 26Mg is selected. MCOL3A/B tuning for true
centre is in progress right now while there is opportunity. |

Beam idle overnight. Beam is being used as a pilot beam for this run. Source was knocked off by a power
bump on Monday evening. Signs are that the root cause is the same as last time, loss of 24V to the IOS interlock panel. |

TUDA-II began taking beam around midnight
last night. Beam on FC6 for a good part of the night. Steady as she goes. |

Beam waiting quietly on FC6. There was a power
bump on Friday just after noon that tripped the world. Keerthi restarted OLIS. Beam never really came back to its former glory. We'll see if there
might be an opportunity to touch it up. |

Beam was redirected to TIGRESS yesterday. RIB delivery to TIDA-II was rendered impossible due to a failure in the target or module. We have a verbal
request in place now to change mass from 26Mg1+ to 24Mg1+. Attached is a plot of beam overnight on FC6 prior to changeover. |

MWS is producing 26Mg, presently parked. It was used over the weekend
for TUDA tuning. |

MWS ran fine overnight. It was shut off this morning to investigate bias sparking issue, noted on FR#4894. The two MCIS turbopump controllers are displaying
gibberish on their front panels this morning. There was one spark since yesterday, around 19:15 last evening. Due to a failure
at ITW - see here and here, |

Photo-finish for TIGRESS this morning, apart from a cavity trip
at around 6:00 a.m.. The MWS is running very well. Some EOB activities underway presently.
Plan for today: MWS pulldown for Mg removal and cleanup. If feasible, we will install the Supernanogan into the OLIS cage as well. |

The experiment ran overnight, smoothly, by the looks of it. Beam is on FC6 now, so they're likely done. EOB studies on Mg beam to commence shortly, with
source teardown and switchover to Rb beam to follow..
Emittance scans in progress, first at as-delivered settings: 5mm slits. Save: 101027_1102>snapiosfc6 |

Beam was switched from 24Mg5+ to 26Mg6+ on Canada
Day. Also, the source blinked out on Saturday. Remote restart okay. Source is running well.
Supernanogan maintenance continues. MCIS optics module was reassembled last week and installed this morning. Also a section of wveguide was replaced |

The MWS was restarted yesterday, and a 26Mg beam re-established. ICR set up into ISAC-II overnight, and tuning to TIGRESS
began this morning. Note the experiment change due to circumstances at the RIB
targets. |

A 26Mg beam was handed over to TIGRESS last
evening. It is 26Mg6+ through ISAC-I and further stripped to 26Mg10+ by the time they get it. Approximately 2.5pnA at FC6. |

Smooth delivery (from OLIS point-of-view) to TIGRESS over the weekend. An SCB RF amplifier failed yesterday and was replaced. Tuning was done. Source
is stable.
There were a couple of bias sparks over the weekend, expected during Mg runs. The mag stability program got knocked off at some point. Restart |

The TIGRESS run was scheduled to end at 08:30, but has been extended for 24h. The ICR reports that they are getting "good data" with the present
beam. Why mess with what works?
We will expect to begin the MWS switchover tomorrow. |

Mass change yesterday morning from 26Mg1+ to 24Mg1+ from the MWS. It was tough to get stable beam from the source, and there are signs of Mg plating
out on stuff. Keerthi was here last evening and again overnight to open the source and clean it up. Good job.
Later... There were a couple of power bumps over the lunch hour. One took out OLIS, the other didn't. Yes, the IOS Enable panel had to get a local |

Tuning into ISAC-II was done yesterday, and continues today. The source was idle overnight. There were a couple of magnesium hiccups. Beam is looking
fine right now. |
