Source pumped overnight to previous baseline (red trace on attached Stripchart). IOPS conditioned it up to 42kV without a hitch.

Close Ne source gas line and pump out flow controller... noticeable improvement.

Bias conditioned up to 50kV.

Bias conditioning at 58.5kV with MW at 600W. Raising the RF outgassed the plasma chamber for the first while then went quiet again.

Bias set to 55.08kV for 27Al+1 run. Source lit around 14:30.

15:30: IOS:FC3 = 1.9e-5 (no bias); IOS:FC6 = 9.3e-9. It's coffee time.

16:40: IOS:FC6 = 4.9e-9 (attached)) after settling and a few little tweaks. We're just about ready.

16:45: Hand it over to ICR.
