论文摘要
粒子能量呼叫被证明是针对高质量致密电子梁的分期激光唤醒场加速度中的有用仪器。 CHIRP是沿纵向方向弥补加速场非均匀性并实现能量分散基本的必要工具。这是通过利用血浆和梁电子分裂技术的粒子模拟来证明的。正确选择的光束呼声可以减少加速到GEV能量范围内每个阶段的数量级的能量分散。
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.
