摘      要：Background The Hefei Advanced Light Facility(HALF)will be a VUV and soft X-ray diffraction-limited storage ring(DLSR),and its high density of electron bunches makes the intra-beam scattering(IBS)effect very *** An IBS module used in the IMPACT code is developed,where the scattering process of IBS is described by the Piwinski model in Monte Carlo *** the IMPACT code with IBS module,the macroparticle beam in storage ring is numerically tracked,including motion under external electromagnetic field and the IBS scattering *** the long-term tracking results of macroparticle beam are statistically *** and conclusions The results of IBS effect in the HALF storage ring studied by this new code are *** benchmarking,the IMPACT code with IBS module is compared with the ELEGANT code and a semi-analytic code using Bane’s model,and the results agree well with each *** various countermeasures,the IBS impact can be controlled to a certain extent,and the expected beam emittance is approximately 59 pm·rad.
