First beam appearing on FC6 presently, after the source pumped overnight. Source gas valving set up earlier this morning.

Later... We have a whopping 5nA of 35Cl1+. We expect orders of magnitude more. Mass scans and investigation in progress.

Later... Another scan after some source gas changes. Much better. 35Cl+1 = 575nA 35Cl+2 = 3.5pnA with 1mm slits.

Neon support gas hand valve is closed. Source wuill require expert intervention to reignite, if there is a power bump, etc.

Later... Final tweaking done. ~10enA on FC6 with 1mm slits in, and ~23enA with 2.5mm slits in. A Stripchart of the last little while, plus present IOS tune and skimmers. Hand over to ICR at 13:25.
