  53   Wed Jul 8 17:47:26 2009 Damien GallopRoutineGeneral18O4+ emittance scansFirst up is a check scan of 18O4+. There
is a definite vertical offset compared to
earlier today. Otherwise, it correlates well

progress. Data file (large): masscorr_mcis_090708.txt.
The source is optimized for 18O4+. Fishing

I settled on the 15.486GHz optimal frequency,
and tweaked that for effect. Then I ran a

the 18O source gas valve, I restarted the
Supernanogan source last evening around 18:00

  47   Tue Jul 7 17:47:14 2009 Damien GallopRoutineGeneral18On+ beam & emittanceAs noted earlier, we have 17O and 18O source
gas attached to the Supernanogan source chamber.
Both are valved off presently. The source

ISIS emittance rig testing this morning.
He ran it, and I tried to find ways to run

reboot occurred mid-afternoon Friday unfortunately.
Operators restored beam at about 06:00 on

MCIS beam on FC3 overnight. A bit inconclusive,
but there may be a temperature correlation.

versus beam current for 16O2+. Starting RF

I noticed a long-term trend in beam
intensity. I have every reason to believe

  39   Tue Jun 30 17:39:13 2009 Damien GallopRoutineGeneralCompare 16O2+ beam from start of run to todayThere seemed to be some small change to
the beam over the week of TACTIC running.
I would like to poke around a bit. The emittance

with both open. Original slit setting was
1mm. Finally, restore slits to 1mm and see

it auto-restarted just before the previous
scan had finished. I thought the resulting

The TACTIC run, which ended around 08:30
today, appears to have been a success. TACTIC

morning to Sophia for TACTIC setup. On our
side, everything went well. TACTIC switched
