摘要
The target parameters of modern ultra-low emittance storage ring light sources are entering into a regime where intra-beam scattering（IBS） becomes important and, in the case of the Beijing Advanced Photon Source（BAPS）, which is being designed at the Institute of High Energy Physics（IHEP）, even a limitation for achieving the desired emittances in both transverse planes at the diffraction limit for X-ray wavelengths（≈10 pm）.Due to the low emittance, the IBS effect will be very strong. Accurate calculations are needed to check if the design goal（εh＋εv =20 pm） can be reached. In this paper, we present the results of numerical simulation studies of the IBS effect on a BAPS temporary design lattice.
