|
| Source set up for a cocktail beam since yesterday, Sunday. |
Tue Oct 18 10:27:44 2011, Damien Gallop, , , 19F/38Ar from MCIS for Beam Development 
|
| Cocktail beams continue today. |
|
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. |
|
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. |
|
Fri Oct 28 10:18:53 2011, Damien Gallop, , , 33S+6 from MCIS to DRAGON
|
| Delivery continued overnight. |
|
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 31 11:06:58 2011, Damien Gallop, , , OLIS Shutdown
|
Two weeks of OLIS Shutdown have begun. The plan is to complete refurbishing this week and pump next week, with 36Ar+6 beam ready at the end of it. IOS
is vented and open. The Supernanogan cart is out, vented and open. Plasma chamber cleaning and refurbishing in situ are in progress. The IOS upstream optics
DB1-3 have been removed for refurbishing on the bench. |
|
Tue Nov 1 10:18:02 2011, Damien Gallop, , , OLIS Shutdown
|
| MCIS pumped overnight. Still coming down. |
|
Wed Nov 2 10:16:49 2011, Damien Gallop, , , OLIS Shutdown
|
MCIS pumpdown continues well. IOS optics coming along. DB3 installed last night and IOS is under vacuum very early. DB1/2 optics will remain out until
the end of the next-up MCIS run. |
|
Thu Nov 3 09:50:05 2011, Damien Gallop, , , OLIS Shutdown
|
MCIS pumped well overnight. Source development imminent.
Later... possible IOS intervention. Spin down turbos in anticipation... Meanwhile, MCIS pressure was at 7.8e-8 Tott at the start, and dropped to
7.4e-8 Torr immediately upon closure of MCIS:IV1. Note that IOS:IV0 remains open with interlocks bypassed. |
|
Fri Nov 4 09:41:32 2011, Damien Gallop, , , OLIS Shutdown
|
MCIS continues to pump well. IOS DB assembly planned for today.
Later... DB assembly complete and IOS under vacuum. Present pressure: 1e-6 Torr at ~18:00. All optics hold voltage. |
|
Mon Nov 7 09:58:17 2011, Damien Gallop, , , OLIS Shutdown
|
IOS pumped well over the weekend. Present pressure is 1.5e-7. MCIS pumps off
for setup.
Later... Supernanogan is online with better than 250enA of 36Ar7+ on FC6 presently ~17:00. Note: MCIS:TP3 is off by intention for this run. |
|
Tue Nov 8 10:02:54 2011, Damien Gallop, , , OLIS Shutdown
|
Supernanogan is online with 36Ar+7 on FC6 overnight. Looks good. Note: The source gas arrangement (enriched 36Ar) utilizes double buffer canisters and
calibrated leaks, and requires MCIS:TP3 off.
Controls is preparing to perform an IOSIOS reboot for the sake of new code for ILT:RPM8 or something like that. |
|
Wed Nov 9 11:40:35 2011, Damien Gallop, , , OLIS Shutdown
|
Supernanogan 36Ar+7 source development in progress. RF frequency scans are the agenda for today.
Later... Some good beam results and 300enA beam on FC6. Note: 5mm slits are in. |
|
Thu Nov 10 09:57:57 2011, Damien Gallop, , , OLIS Shutdown
|
Supernanogan on overnight with 36Ar+7 on FC6. Nice.
Today is the last day of scheduled OLIS Shutdown. Expect more source development today followed by a hand-off to ICR at some point. |
|
Wed May 23 17:11:57 2012, Keerthi Jayamanna, , , Changed beam to 12C++ beam
|
Removed titanium from the back plate and clean the source.
But left the PE titanium insert since Bob and Marco badly want the 12C++ beam from the source fast.
Background 12C++ was only 400pA so installed a small canister with CO in it with bellow atm. pressure. |
|
Sun Dec 2 22:34:09 2012, Keerthi Jayamanna, , , Just finished 136Xe+25. ISAC reached 1GeV yesterday using OLIS Xe beam
|

|
Fri Dec 14 17:30:47 2012, Keerthi Jayamanna, , , 18OH2 and 40Ar+2 delivary
|
During the last week we delivered 18O+2 from microwave ion source to Ritu.
Over the week end changed to 40Ar+2.
Ritu informed us 18OH2 is coming with 40Ar+2. |
