Effect of Skew SX comp. of B Skew SX comp. of B2 seems most severe for vertical beam size. SK2=1 sy=49nm Horizontal beam size does not change for Abs[SK2]<1.5 B2’’/B0=SK2/ANGLE ANGLE=0.0499(B5) 0.0302(B2) 0.0538(B1) B2/B0=1/2 B2’’/B0 r2 SK2=1, r=10mm B2/B0=1.00e-3(B5) 1.66e-3(B2) 9.29e-4(B1) For 5% beam size growth, i.e. sy=37nm(s0y=35nm) SK2=0.74(B5) 0.33(B2) 0.49(B1) Corresponding B2/B0=7.40e-4(B5) 5.48e-4(B2) 4.55e-4(B1) Due to the B strength, the min. B2/B0 is 4.55e-4 for B1
