|
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. |
|
Tue Jun 29 09:16:33 2010, Damien Gallop, , , 24Mg5+ to TIGRESS 6x
|
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. |

| Delivery / standby continues. |
|
Mon Jul 5 11:58:49 2010, Damien Gallop, , , 26Mg6+ for TIGRESS
|
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. |
|
Tue Jul 6 19:10:33 2010, Damien Gallop, , , OLIS Maintenance
|
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 |

Thu Jul 8 09:38:36 2010, Damien Gallop, , , 16O1+ at 32.64keV for accelerator commissioning
|
| Beam idle overnight. Source conditioned and changed a bit. Slight tweaking required to bring it back to stable. |
|
Fri Jul 9 10:00:03 2010, Damien Gallop, , , 16O1+ at 32.64keV for accelerator commissioning 8x
|
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 |

Mon Jul 12 10:55:14 2010, Damien Gallop, , , 16O1+ at 32.64keV for accelerator commissioning
|
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. |
|
Tue Jul 13 18:33:04 2010, Damien Gallop, , , OLIS Maintenance and Development
|
A source switchover day was negotiated, with a goal to provide 12C2+ beam. As a practical matter, it's been an OLIS Maintenance Day, at least for the
morning. Controls installed a cable to provide remote reset capability for the OLIS Enable interlock panel. However, it did not perform as expected first
time, so Controls has elected to pursue this another time. Meanwhile, the remote cable is at the rear of the OLIS Enable panel, ready to be connected next |
|
Wed Jul 14 09:23:19 2010, Damien Gallop, , , 12C2+ for TIGRESS
|
OLIS is set up for 12C2+ delivery, with about 13enA on FC6 from the Supernanogan source presently. Beam was reasonably stable overnight, and should condition
out better over time as well. Initial tuning into ISAC-I is planned to begin this morning. |
|
Fri Jul 16 10:22:35 2010, Damien Gallop, , , 12C2+ for TIGRESS
|
Tuning to TIGRESS is continuing. There is a full expectation that they will take RIB over the weekend.
As it stands, the beam schedule shows switchover from TIGRESS to TITAN on Sunday evening. For a couple of reasons, it would make sense to move
that time into Monday or so. |
|
Mon Jul 19 10:56:53 2010, Damien Gallop, , , 12C2+ for TIGRESS
|
Beam from the Supernanogan remains on standby for TIGRESS pilot beam. There were a couple of source trips over the weekend, at least one a consequence
of a power bump that took out a few other things too.
We have had a couple of pending work permits in the queue for a while. One is for germanium beam development, |
|
Tue Jul 20 09:38:45 2010, Damien Gallop, , , OLIS Maintenance
|
Our work permit to leakcheck the Supernanogan and IOS was signed this morning. The source is off presently, and work is underway. The 12C2+ beam was
not used overnight. |
|
Thu Jul 22 09:25:21 2010, Damien Gallop, , , 74Ge1+ to TITAN
|
The Supernanogan is producing 74Ge using the heater source, a first for the Supernanogan.
Development done over the last couple of days and completed
yesterday. Tuning using mass 76 (76Ge or 76Se?) |
|
Fri Jul 23 13:00:04 2010, Damien Gallop, , , 74Ge1+ to TITAN
|
Beam remained on FC6 overnight. Beam was used for a tune check this morning. At noon today beam was switched to 4He.
Later... Outcome of 4He development with Supernanogan: beam comes with other isotopes. e.g. 12C3+ and 16O4+. Verdict: 4He1+ beam is better produced
with the MWS. |
|
Mon Jul 26 09:41:46 2010, Damien Gallop, , , 74Ge1+ to TITAN
|
Beam is sitting on FC6 presently. Good source operation over the weekend. Some pics to come. RIB delivery to TITAN ended at 08:30 this morning. OLIS
is scheduled for a beam switch tomorrow morning.
Later... A power bump knocked us out |
|
Tue Jul 27 08:55:49 2010, Damien Gallop, , , OLIS Maintenance
|
Today we switch from 74Ge1+ to 4He1+, about as wide a switch as we've done at OLIS. We will use the MWS for the 4He.
Later... sources lit. First mass scan attached. Intensity is pretty low for now.
Later... MWS optimized better. Optimal He gas pressure is somewhere between zero and the leakthrough rate on the flow controller set at zero. Stripchart |
