论文摘要
我们使用两个平行的传播激光脉冲为高度极化的质子梁提供了一个设置，该激光脉冲具有$π$的载体信封相位差。利用粒子中的模拟进行了检查，并将这种机制与通常用于磁性涡流加速的单个脉冲设置进行了比较。我们发现，双脉冲设置的使用允许峰值能量为124 MeV，并且对于两个具有归一化激光矢量电势的脉冲$ a_0 = 100 $的脉冲良好的角度扩散。与单个脉冲相比，我们进一步观察到加速束的极化更高。
We present a setup for highly polarized proton beams using two parallel propagating laser pulses that have a carrier envelope phase difference of $π$. This mechanism is examined utilizing particle-in-cell simulations and compared to a single-pulse setup commonly used for magnetic vortex acceleration. We find that the use of the dual-pulse setup allows for peak energies of 124 MeV and good angular spread for two pulses with normalized laser vector potential $a_0 = 100$. Compared to a single pulse, we further observe higher polarization of the accelerated bunch.
