| 英文摘要 | In this paper, short pulse radiation in Shanghai Synchrotron Radiation Facility (SSRF) is generated by the low momentum compaction factor (alpha(C)) optics, and three kinds of the low-alpha(C) optics are found, with the very low alpha(C) being adopted by reducing dispersion in the straight section to negative value in the SSRF. Energy acceptance is selected as objective functions in nonlinear optimization rather than the second order alpha(C) or other nonlinear driving terms. The optimal result is improved step-by-step by randomly setting harmonic sextupole strengths. Two optics modes, i.e. low positive alpha(C) and low negative alpha(C), are analyzed. In order to get a large energy acceptance and only one stable point in longitudinal phase space, the low negative alpha(C) optics is taken as an operation mode for the short pulse radiation in the SSRF. |
