 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. |
Thu Oct 8 09:39:52 2009, Damien Gallop, , , CSB Development with MCIS 
|
Friedhelm and Marco have requested 20Ne2+ from the Supernanogan, and plan to bring up the same from the CSB today. I am beginning MCIS bias conditioning.
Goal: 24kV, maybe 25. Last save: 091008_0933.snapiosfc6
Later... Conditioning completed to 26kV. Set up a 20Ne2+ tune. It's largely a manual operation. Q3 off in keeping with the failure that occurred |

Wed Jul 15 16:37:01 2009, Damien Gallop, , , Bias for IOS emittance rig
|
Graham looked up the list of IOS bias assignments. None was form the emittance rig. I quickly tested the list in ILT, but nothing jumped out. Keerthi
provided a battery setup, which I have now installed. Here are example scans, untouched, of forward and reverse bias. I leave it to you, dear reader, to
figure out which is which. |

Wed Jun 10 17:49:40 2009, Damien Gallop, Routine, General, Beam to RFQ
|
We handed over the beam to Sophia for testing Rick's new tune. Although there are RF issues at the RFQ presently, her feedback to the operators is so
far, so good. TBC tomorrow morning. Right now, we will open the OLIS cage and install a couple of source gases in preparation for our presentation on Friday. |

Mon Jul 6 10:57:08 2009, Damien Gallop, Routine, General, Beam stability versus temperature over weekend
|
We had 16O3+ on FC6 on Friday. An IOSIOC reboot occurred mid-afternoon Friday unfortunately. Operators restored beam at about 06:00 on Saturday. Beam
came back fine. I requested FC3 in at 18:00 Saturday to get some temperature correlation with total beam. Maybe there is a correlation, but a longer stretch
is needed. Something stopped at 18:00 on Sunday. Keerthi told me this morning that he found steerers off, and switching them on restored beam instantly. |

Tue Sep 8 15:14:45 2009, Damien Gallop, , , Back from vacation
|
I'm back from vacation. Physically, anyway. Keerthi did comprehensive emittance scans during Supernanogan Development over the last couple of weeks.
He is very happy with the results so far. We are doing come post-analysis comparisons presently. Meanwhile, DRAGON is taking 16O3+. Some sideshows, including
power bumps this morning which knocked out MCIS and many other systems. The mag stab facility was offline while I was away. I restarted it around noon. |

| DRAGON has been taking various species of Na and Rb using the MWS. Run ended this morning. Emittance scan of 23Na attached. Mass scan in progress. |

Wed Jul 20 01:37:46 2011, Keerthi Jayamanna, , , Al beam development:
|
Supernanogan is tested for Al+6 beam production.
A 8nA of mass 4.5 is seen. Background pressure is not good enough to
produce
more Al+6. Attempt to increase Al beam current with higher sputtering
voltages resulted in fast destruction of the Al sample.

Tue Nov 18 08:56:23 2014, Brian Minato, Other, General, ALGA Update
|
There has been no noticeable loss of communication to the ALGA 50watt amplifier. As a test, the ethernet cable was removed for about a minute and
then reconnected. The amplifer re-established communication without issue. This test was done twice.
Now, the CPI ethernet cable has been returned to the CPI amplifier. The original ALGA ethernet cable (blue) has been reconnected to the ALGA. |
|
Thu Oct 23 10:52:21 2014, Brian Minato, Routine, General, ALGA Amplifier
|
The ALGA amplifier and its signal generator have been turned off at the request of Controls. They have had communication issues and are looking
for any recent changes. |

Tue Nov 23 10:31:27 2010, Damien Gallop, , , 85Rb for TITAN
|
We are back to running a Rb beam using the MWS. The run started last Thursday, November 18th. The previous Rb run ended on Monday, November 8th, at which
point a 12C2+ beam was established, using both sources; the Supernanogan was selected for final delivery to DRAGON. Users reported excellent beam. That
run ended last Monday, November 15th, after |
|
Wed Nov 24 14:02:14 2010, Damien Gallop, , , 85Rb for TITAN
|
Last day of 85Rb delivery. Save: 101124_1400_snapiostitan. Next up: 12C2+ for SEBT commissioning. We took a few minutes earlier
to see if this is available with the source as-is. No such luck. Plan is to shut off mid-afternoon, and prepare to switch over to 12C2+ operation from
the MWS. |
|
Wed Nov 3 09:22:38 2010, Damien Gallop, , , 85Rb for Polarizer
|
Yesterday we handed over a 85Rb beam to ICR. It will be used for a LEBT run using the Polarizer line. Beam stayed on FC6 overnight. Note the source spark
at around midnight, after which the bias current readback was higher. Real or artifact?
Later... Beam status over last couple of hours. Looks like tuning has begun. |
|
Thu Nov 4 09:18:15 2010, Damien Gallop, , , 85Rb for Polarizer
|
| Source ran nicely overnight. ICR team set up a tune into the Polarizer line. Experiment setup is scheduled to start tomorrow morning. |
|
Fri Nov 5 09:23:53 2010, Damien Gallop, , , 85Rb for Polarizer
|
Beam was used yesterday. Mostly idle overnight. Looks like a plasma mode change happened at around 19:00 yesterday. It happens. Or perhaps just an artifact
again. Shortly after, beam was moved to 87Rb, which is where it is right now. Once again, another milestone first at OLIS: 87Rb from the MWS.
Natural abundance of Rb: Rb-85 ( 72.165% ) Rb-87 |

Mon Aug 15 10:19:18 2011, Damien Gallop, , , 84Kr from MWS to TITAN
|
| The source was configured and switched over on Friday. Some teething pains over the weekend. Beam is on FC6 presently. |
|
Mon Jun 15 17:49:23 2009, Damien Gallop, Routine, General, 84Kr charge states begun
|
We began looking at 84Kr this weekend. Keerthi had 84Kr19+ on FC6 this morning, which I was able to tweak up from ~300epA to about 600epA. Not bad! This
evening it is down to 100pA at best. I think there is a correlation of multi-charge production and room temperature. (It's warm today.) Keerthi noticed
tat an entire mass scan this afternoon was suppressed, where I had a solid scan earlier, the two taken the same way. Let's see what happens to FC6 overnight. |

|
The previous 12C2+ development run from the Supernanogan ended Friday morning. Starting Friday afternoon, the Supernanogan was prepared for an upcoming
SEBT development using krypton beams. The source was ready overnight.
There were some teething pains over the weekend. An A/q=5.71 beam is sitting on FC6 presently. The beam schedule shows an experiment change on Thursday |

| Development should continue today. Looks like Supernanogan went through a plasma mode change overnight and settled into a new mode. |
