论文摘要
在超偏好的透明度状态下，研究了辐射反应和Breit-theeler对的产生对由强烈线性偏振激光脉冲驱动的完全离子碳离子加速的影响。在最初的预期辐射反应和超高激光强度下的配对产生可增强离子获得的能量。电子失去了大部分横向动量，并在向前方向上沿向前方向共同产生的Breit轮毂电子和正电子的对等血浆，而不是以零以上的角度流动的现有电子。我们讨论了如何通过Buneman不稳定性的相位速度的变化来解释这些观察结果，这是通过在相对电子和离子流中利用自由能来帮助突破性地局部策略中有助于离子加速的。我们提供了证据表明，这些非古典作用可以进一步改善这种透明度制度中最高的碳离子能。
The impact of radiation reaction and Breit-Wheeler pair production on acceleration of fully ionized Carbon ions driven by an intense linearly-polarized laser pulse has been investigated in the ultra-relativistic transparency regime. Against initial expectations radiation reaction and pair production at ultra-high laser intensities is found to enhance the energy gained by the ions. The electrons lose most of their transverse momentum and the additionally produced pair plasma of Breit-Wheeler electrons and positrons co-stream in the forward direction as opposed to the existing electrons streaming at an angle above zero. We discuss how these observations could be explained by the changes in the phase velocity of the Buneman instability, that is known to aid ion acceleration in the Breakout-Afterburner regime, by tapping the free energy in the relative electron and ion streams. We present evidence that these non-classical effects can further improve the highest Carbon ion energies in this transparency regime.
