The 16O5+ beam stayed up OK overnight. ICR took some emittance scans this morning. They look interesting. A finer resolution scan is in progress presently. Goals today:

1. Comprehensive mass scan to A/q=100

2. Characterize 16On+ states, including emittance scans where possible.

Mass scan is in progress now. First look is attached below. The full scan is shown in Gabe's Calibrate application. Note the apparent lack of 84Kr, after a night of pumping with the source gas valve closed. A subsequent scan from A/q=0 to 20 is shown next. The same scan zoomed in at yesterday's scale is also shown for comparison of background intensities, particularly 16O5+ with A/q=3.2, which are higher today due to source tweaking this morning. Now I will start a series of emittance scans, starting with 16O5+ as a benchmark. I expect it to be near-identical with this morning's scan.
