DRAGON continues to take MWS beam.
Later... 14:00 EOB. Prepare for Mini-Shutdown. |

Mon Aug 9 10:38:43 2010, Damien Gallop, , , 4He1+ Setup for SCC Development
|
We have a request for changing over the source to 4He1+ operation
from the MWS.
Later... OLIS opened. Canister purged with N2 and pumped via IOS, then valved off and disconnected. ICR has restored a recent 4He1+ tune. |

Mon Jul 18 09:53:05 2011, Damien Gallop, , , 4He from MCIS to HERACLES done Saturday and Sunday
|
Keerthi came in on Saturday morning and set up the Supernanogan source for 4He delivery. It looks like it went well. The original intent was to use the
MWS for this, but sputtering got in the way. He also came in yesterday to tweak the recipe to minimize 16O4+ and 12C3+ (A/q=4) contribution to the beam.
The run finished last night. |

Thu Sep 8 11:21:45 2011, Damien Gallop, , , 4He from MCIS to DRAGON Setup
|
The 58Ni delivery from MWS to TITAN ended last evening. Beam was unused from about 18:30, and source switchover began at about 22:00. A 4He1+ beam from
MCIS was established by 03:00 this morning.
Around 35pA is available on FC6 presently. Note that at A/q=4, there are likely contributions from 12C+3 and 16O+4. |
|
Mon Sep 12 10:04:42 2011, Damien Gallop, , , 4He from MCIS to DRAGON EOB
|
| Delivery continued through the weekend. Some 300nA on FC6. The run ended at around 09:00. Source switchover is in progress now. |
|
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: |
|
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. |
|
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. |
|
Thu Aug 5 18:56:48 2010, Damien Gallop, , , 35Cl2+ setup for DRAGON
|
OLIS off Wednesday morning for source changeover from 16O3+ to 35Cl2+. We have elected to use the MWS for this run. Supernanogan is removed from OLIS
and parked at its service dock. Lots of leakchecking done on both sources. Both sources are under high vacuum presently and improving. MWS will be ready
to start in the morning. |
|
Fri Aug 6 09:50:22 2010, Damien Gallop, , , 35Cl2+ setup for DRAGON 6x
|
First beam appearing on FC6 presently, after the source pumped overnight. Source gas valving set up earlier this morning.
Later... We have a whopping 5nA of 35Cl1+. We expect orders of magnitude more. Mass scans and investigation in progress.
Later... Another scan after some source gas changes. Much better. 35Cl+1 = 575nA 35Cl+2 = 3.5pnA with 1mm slits. |
|
Mon Aug 9 09:09:36 2010, Damien Gallop, , , 35Cl2+ for DRAGON
|
Beam ran quietly over the weekend, with the anticipated intensity drop-off. Source gas canister at ~15"Hg and IOS at 3.3e-7 presently. Several DRAGON
energy changes were done as planned.
Later... at ~09:45 DRAGON is done. |
|
Fri Oct 2 09:38:26 2009, Keerthi, Routine, General, 33Sulfur development completed successfully.
|
Sulfur-33 development completed successfully.
Three times of the requested
amount produced (1e9 x 3) from the source and two times
delivered to the DRAGON for verification.

Wed Sep 30 15:30:04 2009, Damien Gallop, , , 33S6+ from MCIS for DRAGON setup
|
Beam is stable enough to let Marco set up something to DRAGON. We are a couple of days early.
Also, we tested the attenuators, previously noted to be operating oddly:

|
Mon Sep 28 14:12:17 2009, Damien Gallop, , , 33S5+ from MCIS on Friday 25-Sep-2009
|
A sustained 33S5+ beam was generated in the Supernanogan on Friday, September 25th. Attached is a trar plot.
Source gas: SO2 through either of two calibrated leaks: 10-4 and 10-5ccm.
FC6 = 1enA. |
|
Mon Oct 31 11:04:06 2011, Damien Gallop, , , 33S+6 from MCIS to DRAGON EOB
|
Deliver concluded yesterday morning around 09:00.
Pity to have to switch off the source. OLIS is now in its Shutdown. |
|
Mon Oct 24 10:10:34 2011, Damien Gallop, , , 33S+6 from MCIS to DRAGON
|
Delivery since Friday Beam on but intensity
is dropping, suggesting that enriched 33S powder is running out. Plan in place to add more this evening. |
|
Tue Oct 25 09:41:32 2011, Damien Gallop, , , 33S+6 from MCIS to DRAGON
|
Beam petered out earlier this morning after an attempt to tweak the RF frequency. Restored. Plasma was on throughout. ICR has lowered RF amplitude to
match beam intensity to yesterday's running conditions. |
|
Wed Oct 26 10:17:53 2011, Damien Gallop, , , 33S+6 from MCIS to DRAGON
|
Delivery continued uneventfully overnight
and is continuing.
Later... source is just getting better and better. See Stripchart below. |
