对波荡器谐波辐射的空间分布作了分析 ,并对上海同步辐射装置 (SSRF)的波荡器U3 6 5辐射强度的空间分布进行数值模拟研究。在此基础上 ,探讨了波荡器辐射的接受孔尺寸选择 ,并模拟计算了SSRFU3 6

Theoretical discussion of spatial photon distribution of undulator radiation was presented, and the result of spatial photon distribution of SSRF U3.65 was given by numerical simulation. According to the spatial photon distribution, the selecting aperture dimension was determined, and transmission photon flux and power through aperture were calculated. The spatial photon distribution at fundamental resonant energy and third harmonic energy from SSRF U3.65 were described. The tuning curves for the flux through aperture and the curves for the bandwidth of radiation at fundamental resonant wavelength from SSRF U3.65 with respect to aperture were plotted.
