[FFA_CEBAF_Collab] [EXTERNAL] Re: FFA at CEBAF WG mtg. this Friday, May 30

[Berg, J Scott]

A couple more thoughts on the discussion we had:

  *
What about putting the cell on a mover that lets us change x-z, to help with setting up different initial conditions?
  *
I'm mildly concerned with a design where we can only probe one side of the aperture, and close to the limit. There seems to be a lot of risk there (beam is not in the mood to reach the energy, magnets come in with a lower Br than expected, etc.). How about a design where we don't quite imitate our cell, but maybe use the same magnet cross sections, but remove one or two slices from each magnet? We could even see if we could have two options, one where we remove the end slices, and one where we have all the slices. I'm being sloppy on details here, so maybe it's not as straightforward as I'm imagining, but it seems something like this could be made to work.

Hi All,

Great discussion today. Attached are the meeting notes (FFA_at_CEBAF_Minutes_20250530.pdf<https://urldefense.com/v3/__https://jeffersonlab-my.sharepoint.com/:b:/r/personal/tristan_jlab_org/Documents/Grad*20Student*202019/Graduate*20Student*20Steering/CEBAF*20FFA*20Working*20Group/Minutes/FFA_at_CEBAF_Minutes_20250530.pdf?csf=1&web=1&e=5tBLcc__;JSUlJSUlJQ!!P4SdNyxKAPE!Hth8QVRfyn3UHMdYpmsUIuQaHu7wl7enJtqrepyyyPNres8ltwkhDBquAHIBTrSS8cL07zX9yEwDBFKmHyDGs-zE5g$ >).

Have a great weekend,
