  453   Wed Oct 19 09:53:27 2011 Damien Gallop  33S from MCIS to HE Development Setup

MCIS configured for 33S+6 yesterday afternoon. Beam grew nicely overnight. Beam development expected after source hand-off.

  452   Tue Oct 18 10:27:44 2011 Damien Gallop  19F/38Ar from MCIS for Beam Development

Cocktail beams continue today.

  451   Mon Oct 17 11:33:03 2011 Damien Gallop  19F/38Ar from MCIS for Beam Development

Source set up for a cocktail beam since yesterday, Sunday.

  450   Thu Oct 13 11:11:14 2011 Damien Gallop  14N+2 from MWS to SEBT for Beam Development

Source setup took place earlier this morning.

  449   Thu Oct 6 15:15:09 2011 Damien Gallop  19F/40Ar from MCIS for Beam Development

Slit calibration exercise was wound up this morning. MCIS source gases were reconfigured with 19F and 40Ar by request. A "cocktail" beam will be used for HE development over the Thanksgiving weekend. A mass scan is in progress presently.

  448   Wed Oct 5 10:11:28 2011 Damien Gallop  33S from MCIS Source Development

The source stayed up overnight. A little RF tweak, but 33S+6 beam still on FC6.

Later... IOS:MCOL3 slits calibration with beam in progress.

  447   Tue Oct 4 10:37:38 2011 Damien Gallop  33S from MCIS Source Development Setup

Beam development with 116Sn+18 finished last evening around 21:00. Source was off overnight. 33S material loaded into MCIS oven. Source pumped overnight.

Later... source is lit. 33S+6 on FC6 and growing.

  446   Mon Oct 3 10:08:50 2011 Damien Gallop  116Sn+18 & 118Sn+19 from MCIS for Development

On Friday there was a request to repeat some of the findings with tin beams. An agreement was made to use OLIS for development in lieu of Shutdown MRO as scheduled. MRO is planned for November 2nd &ff. HE development took place over the weekend with 116Sn+18, A/q=6.44.

Next up: 33S source development. Setup this evening.

  445   Thu Sep 29 10:50:30 2011 Damien Gallop  36/40Ar development with MCIS

Development with Supernanogan source continues. Present beam is 40Ar+7, about 70enA.

  444   Wed Sep 28 11:56:15 2011 Damien Gallop  36/40Ar development with MCIS

40Ar source gas, ergo 40Ar+x beams. 40Ar+6 earlier, and 40Ar+7 presently.

  443   Tue Sep 27 13:29:23 2011 Damien Gallop  36/40Ar development with MCIS

Beam development for forthcoming 36Ar run is in progress. Initial yield numbers have been determined. Source is running with Ar plasma presently, and tests will be repeated after source has conditioned for a while. The goal is to determine yield numbers of 40Ar and scale these to beam to be produced with source gas of enriched 36Ar. FYI:

Naturally occuring isotopes of argon:

Ar-36 ( 0.3365% )
Ar-38 ( 0.0632% )
Ar-40 ( 99.6003% )

  442   Mon Sep 26 09:47:12 2011 Damien Gallop  13C+3 from MCIS to TACTIC

The 17O+3 (A/q=5.66) run to TACTIC finished yesterday morning. Then a source switchover was done to deliver 13C+3 (A/q=4.33) using enriched 13CO2 source gas.

Later... TACTIC is done. Next up: beam development at MCIS for upcoming 36Ar run.

  441   Fri Sep 23 14:59:14 2011 Damien Gallop  14N+3 & 17O+3 from MCIS to TACTIC at HEBT

Delivery continues. 14N+3 until mid-morning, then a switch to 17O+3 for tuning. The switchover from 116Sn to TIGRESS to 14N+3 to TACTIC was done on Tuesday mid-morning.

  440   Mon Sep 19 10:27:36 2011 Damien Gallop  116Sn+18 & 118Sn+19 from MCIS to TIGRESS

Delivery continued over the weekend with some interruptions here and there. A source intervention was made late last night and into the wee hours, and again this morning. Tuning to TIGRESS has resumed.

Note that ICR was using a 12C+2 beam for setup purposes. Their procedure was to turn off MCIS when beam not in use to minimize carbon contamination in the source. 12C+2 -> 116Sn+18 last evening around 21:00 with source expert present.

  439   Fri Sep 16 10:02:33 2011 Damien Gallop  116Sn+18 & 118Sn+19 from MCIS to TIGRESS

Beam was changed to 14N+2 last evening for sake of tuning to front of RFQ. Source was tweaked earlier. Beam is presently set to 116Sn+18 with tuning activities in progress.

  438   Thu Sep 15 12:09:25 2011 Damien Gallop  116Sn+18 & 118Sn+19 from MCIS to TIGRESS Setup

Source switchover began last night after 22:00. There are some 200epA of A/q=6.46 (116Sn+18) on FC6 presently. Setup and tuning continue.

Natural abundances of Sn:

Sn-116 ( 14.54% )
Sn-117 ( 7.68% )
Sn-118 ( 24.22% )
Sn-119 ( 8.58% )
Sn-120 ( 32.59% )
Sn-122 ( 4.63% )
Sn-124 ( 5.79% )

Later... ~70epA at FC6 after some conditioning and fiddling.

  437   Thu Sep 15 11:29:39 2011 Damien Gallop  12C+2 from MCIS to DRAGON EOB

Beam delivery was scheduled to end last evening at 20:30. It was extended to around 22:00, at which point source switchover began.

  436   Wed Sep 14 10:00:05 2011 Damien Gallop  12C+2 from MCIS to DRAGON

Delivery continues. Nice consistency. See attached Stripchart. A source switchover is scheduled for today, tonight, as it turns out. Good luck with that.

  435   Tue Sep 13 10:00:56 2011 Damien Gallop  12C+2 from MCIS to DRAGON

Delivery continued through the night. User was taking the beam. Recovery from a DTL tank trip is happening at the moment. Otherwise, beam is very good. And strong.

  434   Mon Sep 12 10:07:36 2011 Damien Gallop  12C+2 from MCIS to DRAGON Setup

Setup began around 09:00. 400enA of A/q=6 on FC6 presently.

Later... By ~14:00 beam looks pretty good. See Stripchart below.
