By agreement, we are providing OLIS beam to the Beam Delivery group for the purpose of checking out transmission in the 8pi line. We have set up a 20Ne1+ beam at 28keV. There are some 3nA on FC6.
Here are optics numbers for IOS section:

An initial emittance scan is attached, raw and filtered. A higher resolution follows. Surprisingly, it is grainier than the earlier one. Slits are at 5mm setting.
Milestone note: The commencement of using this beam today at around 14:00 marks the first time in ISAC history that a filament ion source is used to deliver a beam to a user. Hooray! |
