• 100 Hz, two bunch; to drive two HXR line with 65 MV/m gradient

• 250 Hz, two bunch to drive two SXR line with ~20 MV/m gradient

• 100 Hz, two bunch to drive SXR & HXR line with 65 MV/m gradient

~300 MeV~50 fs

~1 GeV~2-50 fs

~3-5.5 GeV~2-50 fs For HXR at 100 Hz

Funded by the

European UnionBasic Lattice

• FODO type of lattice is going to used• But FODO is simple to operate, less number of elements etc..

• Instead of BPMs wakefield monitors (Andrea)

• Instead of independent correctors integrated quad-corrector is proposed (Jim)

• Number of structures between quads can be: 1, 2, 4 (3 is not preferable) (Walter)

For long time we could not make meeting, most of the

talks are reminder and status..

• XLS parameter update: James Anthony Clarke

• Comparison of Injector Options:Anna Giribono

• S-Band Based Injector Layout: S2E modelling:Edu

• Discussion¶

Funded by the

European UnionMeeting at Frascati

• we are supposed to decide the injector for CompactLight. But on which comparative terms?

• Comparison of a common system, e.g. Injector + magnetic compressors at 300 MeV or up to 2nd BC?• like length

• number of elements

• sensitivities to various dynamic imperfections

• risk factors

• charge profile,

• uncorrelated energy spread
