We completed the services by end of last week. Of course they could always be better, but everything is fine for this iteration. Keerthi had a first beam out of the source (to FC3) on Friday, with no source gas flowing. Today we started it up, and got first beam this morning. First 4He beam was observed on FC6 at around 10:45, and 4He2+ a few minutes later. Plenty of development to go, but it works.

Later... Light it up and tweak. Filament is at 125A and arc at 100V. Bias is 10kV. 4He2+ on FC6 = 580enA. Save: 091130_1600.snapiocf6

Let it sit for a while. Filament p/s is running in local and V regulating mode for safety.

Latter... Stripchart attached of beam and playing over the last hour. It would be nice to have a loop adjusting the EL against SK-MSBR, which seems to track beam at FC6 quite well. Source on for the night to condition. ICR apprised.
