Abstract :
The chromatic effects of the phi -factory lattice are analyzed to optimize the location of the sextupole correctors. Five families of sextupoles are envisaged to compensate for the tune chromaticity as well as the chromatic dispersion and beta -functions. The approximate pi -relations in the betatron phase between the sextupoles are pursued to preserve the dynamic aperture, while the tolerance of breaking these relations is determined from the Hamiltonian treatment. Computer simulation results are discussed regarding the phi -factory lattice dynamic aperture and taking into account the synchrotron motion.<>
