合肥800MeV电子储存环同步辐射特性

Characteristics of Synchrotron Radiation Emitted by Hefei 800 MeV Electron Storage Ring

以石英卤钨灯作为光谱辐照度标准光源，测量了在３００～８００ｎｍ波段的合肥８００ＭｅＶ电子储存环同步辐射的相对光谱分布；并在４０５ｎｍ波长处测量了辐射源的角分布和偏振特性．在实验误差范围内，测量结果与理论计算值相符．相对光谱分布偏差为１．５％，角分布和偏振特性偏差小于５％．

The relative spectral distribution of synchrotron radiation emitted by Hefei 800 MeV electron storage ring was measured in 300 ～ 800 nm range, by using quartz tungstan halogen lamp spectral irradiance working standard source. The polarization and the angular distribution were investigated at 405 nm. Within the experimental error, a good agreement was found between experimental results and values predicated by theory of synchrotron radiation derived by Schwinger. The difference of relative spectral distribution is less than 1.5%, and the angular distribution and the polarization is less than 5%.
