摘要 为了研究在激光驱动的尾场中被加速正电子的动能,采用数值模拟方法,得到了非对称sine脉冲、flat-top脉冲和Gaussian脉冲驱动的尾场中被加速的正电子的能量。结果表明,非对称sine脉冲驱动尾场中正电子得到的能量比flat-top脉冲和Gaussian脉冲驱动尾场中得到的能量高一些。 In order to study the kinetic energy of the accelerated positrons in the wakefield of different laser pulses, by means of numerical simulation, the kinetic energy was obtained in the wakefiled of sine, fiat-top and Gaussian asymmetric laser pulses. Simulation results show the energy driven by asymmetric sine pulses is higher than those driven by fiat-top and Gaussian laser pulses.
