|
Setup into ISAC-II began last night. Tuning is in progress now. Beam on FC6 overnight. Canister pressure is -22"Hg and MCIS pressure=7.1e-8 Torr.
Pressure showed correlation with temperature. It is overcast today and cool, suggesting a fairly flat response today. |

Delivery to TIGRESS began yesterday
or so. ICR reported beam intensity drops overnight. I'll look at it presently. Meanwhile, canister pressure is still ~-22"Hg and MCIS pressure is
7.09e-8 Torr. |

|
Delivery of 15N4+ to TIGRESS continues. Source gas canister is still at ~-22"Hg, and MCIS pressure is 7.2e-8 Torr. ICR reported intensity drops
a couple of times this morning. The attached Stripchart suggests beam from the source is down to about a third from status quo. We will look into it now. |

Sat Jun 12 10:20:14 2010, Damien Gallop, , , 15N4+ to TIGRESS done 13x
|
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. |

|
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. |

|
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. |

| Delivery looks like it was pretty smooth over the weekend. TIGRESS expects to receive 24Na from ITW via the CSB this week. Yield goes today. |

|
Delivery to TIGRESS has begun. Beam from the source looks perfect. Looks like happy times for them. The plan is to eventually deliver 24Na5+ via the
CSB. Maintenance Day for the radioactive lines is in progress now.
Later... This is about as good as it gets for magnesium beams from the MWS. Attached are screen shots of the source setup. |

|
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 |

Tue Jul 6 08:57:33 2010, Damien Gallop, , , 26Mg6+ for TIGRESS EOB
|
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. |

|
Source pulled down for Mg removal and cleanup. Done. Supernanogan refurbishing of MCIS optics complete, plus a comple of other items. Opened joints leackchecked
and okay. MCISIOC was in a partial state, where devices worked but not interlocks. It turns out that Controls knows about this. Msg to investigate in the
morning. Meanwhile, MWS is up with a 16O1+ beam on FC6 presently. FYI, the vacuum pumpdown curve during leakcheck and startup operations. |
|
Wed Jul 7 15:21:36 2010, Damien Gallop, , , 16O1+ for SCC Commissioning
|
A 16O1+ beam from the MWS is being used for SCC development and commissioning by agreement. Some sideshows getting there.
Later... At approximately 13:15, some event, a bias spark, it appears, took out a number of devices, most of which IOPS reset. The FUG blew a fuse
on startup. Replacement OK. However, there remains an interlock light on the IOS:BIAS panel with no apparently unsatisfied interlocks showing. Controls |

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