There is a persian proverb says: " Universe has ear and eyes"
also there is another one says: " The wall has mouse, and mouse has ears"
It was not so easy to optimise the dipole magnet design with gradient and saturation fields, also give the results to beam physics person, to see how much harmful are the multipoles. It is still not finished, though i think the yesterday design would be good enough from the multipoles effect on the dynamic aperture.
