The 16O3+ DRAGON run just finished. MCIS Development begins this morning for a few days. The goal is to install and characterize the new sputter ion source.

Below are vacuum pics before and after closing MCIS:IV0. There was a bit of a spike during closing. All three turbos switched off. TP3 is down now.

Later... Keerthi requests we look at 16O7+ production as a measure of source performance. Done. Chart appended below, with source panels. Mass scan next.
