本文采用电子计算机数值分析方法对静电离心系统中电子的非圆轨道运动的规律进行了研究,通过大量的数值计算、分析和研究发现:电子做非圆轨道运动时,其运动存在着角向和径向周期性,且这种周期性只与电子的横向注入速度、注入位置及系统中所加的静电电压有关,而几乎与其横向注入角度无关;不同参量下的电子运动的径向周期与角向周期之比均趋近于同一常数;当电子注的横向注入速度较小(≤0.35c)时,电子运动的径向周期与系统中所加的静电电压的平方根成反比;不同参量下的电子运动的径向周期均近似等于相应系统中的特征振荡周期。
In this paper, the electronic numerical method is used to study the law of non-circular orbit of electrons in the electrostatic centrifugal system. Through a great deal of numerical calculation, analysis and research, it is found that when the electrons do non-circular orbit, Radial periodicity, and this periodicity is only related to the lateral electron injection speed, implantation position and electrostatic voltage applied in the system, but almost independent of its lateral injection angle; the radial period and angle of electron movement under different parameters When the electron injection lateral injection speed is smaller (≤0.35c), the radial period of electron movement is inversely proportional to the square root of the electrostatic voltage applied in the system. The radial period of electron motion is approximately equal to the characteristic oscillation period in the corresponding system.
