【摘要】：為了研究超強(qiáng)激光與相對(duì)論電子束相互作用中的正負(fù)電子對(duì)產(chǎn)生等量子電動(dòng)力學(xué)效應(yīng),用二維粒子模擬方法對(duì)相互作用中產(chǎn)生的光子和正電子的空間分布和能譜進(jìn)行了數(shù)值模擬研究。探討圓偏振和線偏振激光條件下光子和正電子密度和能量分布的變化情況。結(jié)果表明,圓偏振激光條件下可以產(chǎn)生更多能量更高的光子和正電子。
[Abstract]:In order to study the equivalent quantum electrodynamics effect of positron and negative electron pair in the interaction between super laser and relativistic electron beam,The spatial distribution and energy spectrum of photons and positron produced in the interaction are numerically simulated by two-dimensional particle simulation method.The variation of photon and positron density and energy distribution in circularly polarized and linearly polarized lasers is discussed.The results show that more photons and positron with higher energy can be produced under circularly polarized laser.
