|
20Ne1+ set up from the MWS and handed over to Sophia & Marco for accelerator recommissioning. Strip to 5+ at M:5. First day of beam. Happy St. Patrick's
Day.
Later... a Stripchart of beam today: baby-blue trace is FC6. Also, here are screenshots of the source. |

|
Partial disassembly of DB1 optics today. Shielding of insulators is definitely working and indicated for unshielded insulators. Discussion of possibilities
in progress. Wiring looks good, but one Kapton wire snapped at the connector upon disassembly (no force required). |

|
Preparations for rewiring the DB1/3 optics have begun. Sgan gas manifold work is in progress. Note: IOS:MP1 is scheduled for refit service shortly. We
received major rebuild kits a few days ago, one to replace the kit used when the previous MP1 failed last fall. It is not likely this pump requires it;
only the standard seal kit. |

|
Supernanogan cart removed from Faraday cage to dock today. Some beam safety tests on FC6 in progress presently. FC3 was already removed for replacement.
Optics Photos: Lots taken; selected ones here as time permits.
3-Way Switch (DSCN7285.jpg & DSCN7286.jpg) looks pretty good. There is some discoloration on a downstream insulator, but far from worrisome. |

Wed Feb 10 17:18:24 2010, Damien Gallop, , , OLIS Shutdown in progress
|
OLIS Shutdown has been in progress for a week. IOS is vented, was swiped clean and opened. DB3 was craned out, a precision job. Note to whover reinstalls
this box: Request Lu Sun to do it. He knows exactly how to tension the ropes so that the seals are not at risk of damage. Upstream optics
in DB1 were also removed in the standard three sections. No problem removing them. Photos and commentary to follow. Bellows downstream and ahead of separator |
|
Wed Feb 3 16:30:02 2010, Damien Gallop, , , OLIS Shutdown began today
|
We prepared stuff last night. This morning we vented IOS to argon, then swiped. Clean. Lu and Ajit craned out DB3 for us. Nice job, as usual. We will
remove it and its neighbors to the ISIS Lab for refurbishing. OLIS Shutdown is scheduled to go until March 10th. |

Tue Feb 2 10:06:41 2010, Damien Gallop, , , Supernanogan development wind-up 9x

We ran 32S5+ overnight. Keerthi has been working with the new surface source oven for the last couple of weeks. His results to come. Meanwhile, here
are a stripchart of overnight beam plus a few panels after my tweaking. Slits are at 5mm position.

Thu Jan 14 09:57:05 2010, Damien Gallop, , , 20Ne1+ beam from MWS for 8pi diagnosis 9x
|
Beam is on for 8pi diagnosis by special request.
We set up beam in IOS yesterday. However, beam blinked out last evening, likely due to insufficient source gas pressure. Source restarted with
just a little difficulty this morning. ICR adjusted downstream IOS optics to match into next section. Looking good, and they are tuning now, ~10:00 a.m. |
|
Wed Jan 13 18:16:22 2010, Damien Gallop, , , OLIS development with MWS at 28keV 6x
|
We will be delivering a 28keV beam to the tuning boys tomorrow for further diagnosis of the 8pi line. In anticipation, I restarted the MWS with 20Ne1+
beam. With slits out, there are around 2uA on FC6. Emittance scan of current tune below.
Same tune again with slits in a 1mm, emittance scan attached. |

Mon Jan 11 17:46:31 2010, Damien Gallop, , , OLIS development for 4He2+ beam loose ends
|
OLIS was shut down over Christmas. We did a "soft start" of the MWS last Tuesday, after refurbishing and installation before Christmas. Worked
like a jet.
Today: 4He2+ beam development + emittance scans. Here is the best so far. |
|
Mon Jan 11 17:40:07 2010, Damien Gallop, , , Happy New Year!
|
| Welcome to 2010. Shutdown is underway across the site, while beam development is going on at OLIS. |
|
Thu Dec 24 10:13:00 2009, Damien Gallop, , , OLIS development 20Ne1+ from MWS
|
The MWS stayed up flawlessly overnight. Beam grew from about 2µA to over 5µA this morning. Was it the pre-conditioning of the RF generator?
We will look at the beam for a bit now, then shut it down for Christmas. |

So... lots has happened.
* Supernanogan *
Heater components installed in plasma chamber. Cart reinstalled into Faraday cage. Scroll pump rebuilt! (Thanks, Dan and Edi!) Pumping started |

Mon Dec 21 10:22:33 2009, Damien Gallop, , , OLIS development for CUSP source - installation cont'd
|
Keerthi and Marco achieved visible 4He2+ through the RFQ on Friday (or so). Mass spec attached. Development continues today.
Update: First visible A/q=2 beam through the RFQ at about 14:00 on Friday, December 18th, seen on M:5, an historic milestone for ISAC. Beam later
observed on MEBT spectrometer around 16:00. |
|
Fri Dec 18 13:14:01 2009, Damien Gallop, , , OLIS development for CUSP source continued 9x
|
Yesterday: Busy! Source filment changed last night. Source pumped overnight. First start this morning.
Today: Busy! Nutshell: A/q=2 passed to Marco for isotope verification at MEBT.
Later ~16:00 Beam on MEBT:FC5, an historic first for achieving A/q = 2 through RFQ. 1.6enA of (likely) 4He2+. Tuning to FC7 continues. |
