[FFA_CEBAF_Collab] FFA at CEBAF WG mtg. this Friday, Jan. 5

[Roger Ruber]

Hi,

Apologies I missed the discussion this morning. I see in the minutes there
was a discussion about the CEBAF energy (20 or 22 GeV) and required SRF cryomodule
upgrades to keep the energy.

Probably this was already discussed earlier, so apologies for my question:

What are the approximate energy acceptance windows for the FFA arcs?

That would determine how many cavities/cryomodules we can afford to lose 
before we have to stop operation. Also, it would strongly point to how much
gradient headroom we want for acceptable operation.

With best regards,
Roger.
