1 同步辐射的产生及特性同步辐射是存在于高能电子同步加速器和电子储存环中的电磁辐射现象。科学家在50年代的理论研究中描述了宇宙线中的高能电子在进入地球磁场后所产生的辐射性质,给出了辐射强度、角分布、波谱、极化等特性分析。粒子加速器专家也给出了高能电子在环形加速器中辐射性质,指出了电子能量丢失的原因。通过对电子运动的计算,可以得到同步辐射功率、辐射张角、光子特征波长和特征能量等参数。
1 Synchrotron radiation generation and characteristics Synchrotron radiation is the phenomenon of electromagnetic radiation existing in high-energy electron synchrotron and electron storage ring. In the 1950s, scientists described the radiation properties of high-energy electrons in cosmic rays after they entered the Earth’s magnetic field. The characteristics of radiation intensity, angular distribution, spectrum and polarization were also given. Particle accelerator experts have also given the radiation properties of high-energy electrons in a ring accelerator, pointing out the causes of electron energy loss. Through the calculation of the electron movement, the parameters of synchrotron radiation power, radiation angle, photon characteristic wavelength and characteristic energy can be obtained.
