The intensity of virtual sextupole and the spiral step for the typical synchrotron are obtained theoretically. A customized synchrotron of extraction components placed in dispersion section is designed and the tracking code of slow extraction is developed, thus the theoretical spiral step is comparative studied. To study the beam loss, three layouts of extraction are also designed based on the synchrotron. The result shows that the beam losses at extraction point are different for three cases and it is advantage to beam loss for extraction components placed in dispersion-free straight section.
