摘要:

研究了带相反电荷的粒子相互作用过程中辐射反应(束辐射)对粒子动力学的影响。结果表明,由于光束辐射,光束聚焦可以得到很强的增强。导出了包含辐射反作用力的运动方程的近似解析解。计算了经典区和量子区的束致辐射破裂参数。通过QED-PIC模拟验证了该模型的正确性。本文还建立了在相互作用过程中经历多个电子感应加速器振荡的长束的正面碰撞模型。结果表明,束辐射增强破裂效应在未来的强流粒子束轻子对撞机中将发挥重要作用。

英文摘要:

The radiation reaction (beamstrahlung) effect on particle dynamics during interaction of oppositely charged beams is studied. It is shown that the beam focusing can be strongly enhanced due to beamstrahlung. An approximate analytical solution of the motion equation including the radiation reaction force is derived. The disruption parameter is calculated for classical and quantum regime of beamstrahlung. The analytical model is verified by QED-PIC simulations. The model for head-on collision of long beams undergoing a number of betatron oscillation during interaction is also developed. It is demonstrated that the beamstrahlung-enhanced disruption effect can play a significant role in future lepton colliders with high-current particle beams.
