Optimal 3.0 based Layout 1 with normal bending angle of the existing ATF bending magnet.

Optimal 3.0 based Layout 2 with the modified bending angle of the existing ATF bending magnet. ( 15mrad weaker than nominal bending angle )

Optimal 3.0-like Extraction Optics

Dispersion Matching and Phase advance between kickers were fixed.

but … The distance between bends should be extended by 3 m.The K-value of QP9X is too strong (～ 2.5 ).
