|
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. |

|
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. |
|
Mon Apr 26 10:58:46 2010, Damien Gallop, , , 16O1+ at 32.64keV to SEBT2
|
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. |

|
Nominal beam operation to SEBT2 overnight. A chart of beam over the last few days is attached. There is a step change in the separator field right around
midnight. Although the archive does not show it, in fact this was adjusted at 23:54 last night.

Beam delivery continued nicely through the night.
Yesterday Controls repaired and reinstalled the MCISRFIOC computer. It is working well. More details to come. |

| Another quiet night of beam to S1151. |

|
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. |

|
Mid-morning the source was switched over from 16O1+ to 22Ne2+ operation for a new experiment. OLIS will be used as the pilot beam during this 11Li run
to SEBT1/TUDA-II. |

| Beam was switched on Friday morning from 16O1+ to 22Ne2+. This time it's a pilot beam for a 11Li experiment. |
|
Tue May 4 14:19:18 2010, Damien Gallop, , , 22Ne2+ at 22.44keV for SEBT1
|
Beam from MWS continues for pilot beam use into SEBT1. There are cyclotron issues with cryogenics, so 11Li delivery from ITE is suspended temporarily.
Later... we purchased a small UPS for the MCISRFIOC server. It arrived yesterday. After overnight charging, we installed it today. This is in response
to the hardware failure a couple of weeks ago. |

| Beam on standby for pilot beam. Cyclotron is still down with vacuum troubles since ~03:00, so no RIB to ISAC. |
|
Thu May 6 14:33:07 2010, Damien Gallop, , , 22Ne2+ at 22.44keV for SEBT1
|
Beam from MWS remains quietly sitting on FC6, on standby for pilot beam use to SEBT1. The cyclotron is still down with cryogenerator issues. Latest prediction
is first protons this evening. |

Fri May 7 12:29:41 2010, Keerthi Jayamanna, , , Supernanogan development
|
Supernanogan development for 33S started. All MW and MW and MCIS power sypplies are off.
Gas for microwave source also closed from hand valve
Later... separator field stability development. Local Hall probe is online. Let it cook. |
|
Mon May 10 09:39:34 2010, Damien Gallop, , , 22Ne2+ at 22.44keV for SEBT1
|
Supernanogan development, mainly for the sake of the upcoming 33S run, took place for a little while on Friday. It was expected to go through tomorrow
(Tuesday), but we got the call for beam on Friday evening just before the Canucks game started. So it's up again. The beam was used for a while on Sunday
to check beam energy. |
|
Mon May 10 16:42:55 2010, Damien Gallop, , , Supernanogan development
|
By agreement, the source came down this morning for continuing Supernanogan development. Main event: leak detecting.
Later... Robert and Tim lead leak detectors. Synopsis: A minute leak at waveguide flange on plasma chamber. We decided to seal it with a drop of
vacuum sealant. Worked like a jet. Once Supernanogan beams are done for this beam schedule, we will remove the waveguide and re-machine and weld the flange. |
|
Tue May 11 08:55:41 2010, Damien Gallop, , , Supernanogan development
|
Leak checking on the Supernanogan continues today. We are preparing for an up-coming 33S run, for which we want "perfect" vacuum. We're close.
Later... MCIS backing line is now running on leak detector only. Calibration in progress... Done.
There was a short MCIS vacuum excursion at ~09:15. There were two similar ones overnight. Probable cause: sealant outgassing. |

Back to pilot beam status as of around 18:00 last night. A couple of sideshows through the evening. ICR made an elog entry about the IOS:MB field stability
program here. But the information shown
is inconclusive. As noted in a work permit, Magstab is in fact using our |

Beam continues to be reserved for E1147 pilot beam use. Beam was nice and stable overnight, as expected. Beam (blue) followed source (red), independently
of ambient temperature, roughly reflected in the nearby Supernanogan plasma chamber temperature (maroon).
Later... at 10:14 today there was a sitewide power bump due to an HPL test. It tripped the cyclotron and one isolated ISAC ion gauge. The ICR operators |
