粒子能量啁啾被证明是分级激光尾流场加速的有用工具，旨在产生高质量的密集电子束。啁啾是补偿纵向加速度场的不均匀性并实现能量分散的本质减少的必要工具。这通过利用等离子体和束电子分裂技术的细胞内粒子模拟得到了证明。正确选择的光束啁啾可以在加速到 GeV 能量范围的过程中使每个阶段的能量色散减少一个数量级。
Particle energy chirp is shown to be a useful instrument in the staging laser wake field acceleration directed to generation of high-quality dense electron beams. The chirp is a necessary tool to compensate non-uniformity of acceleration field in longitudinal direction and achieve essential reduction of energy dispersion. This is demonstrated via particle-in-cell simulations exploiting the splitting technique for plasma and beam electrons. Properly chosen beam chirps allow decrease in the energy dispersion of order of magnitude in every single stage during acceleration to the GeV energy range.
