Source started. 33S5+ beam on FC6 using gas flow determined yesterday. At first blush, it appears we need a slightly higher flow. But for now we will spend some time optimizing with what we have. We may open and adjust the flow later.

Later... This flow is okay for now. It requires a *really* fine control, which we do not have at present. 3enA with 10W of power. One source spark about a half hour ago. Mainly it knocked off the separator PS. Spill characteristics are slightly different also.
