Positron acceleration in the wakefield of symmetric and asymmetric laser pulses

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,得到了在对称高斯脉冲和非对称高斯脉冲驱动的尾波场中被加速的正电子的能量。结果表明,非对称高斯脉冲驱动尾场中的正电子的能量比对称高斯脉冲驱动尾场中的正电子的能量高。

Abstract: In order to study the kinetic energy of accelerated positrons in the laser-driven wakefield, the positron kinetic energy in the wakefield driven by symmetric and asymmetric Gaussian laser pulse was simulated. Numerical result shows that the positron kinetic energy driven by asymmetric Gaussian laser pulses is higher than that driven by quasi-Gaussian laser pulses.
