判断同步辐射偏振方向的一种方法

A METHOD TO DETERMINE THE POLARIZATION DIRECTION OF SYNCHROTRON RADIATION

电子在磁场中作加速运动时所发出的辐射一般为椭圆偏振波．本文将同步辐射的偏振特性与电子运动的回旋方向和视轨迹形状联系起来，得到了由观察者的位矢与磁场方向的夹角θ和电子运动方向与磁场方向之间的夹角α之间的关系来确定同步辐射的偏振特性的方法．

The radiation from an electron gyrating in a magnetic field is general elliptical polarization waves.The characters of the elliptical polarization waves can be determined by the angle between position vector of the observer and direction of magnetic field and by the pitch angle of the electron in the magnetic field.
