本文对长质子束团在沿束路沿着有线性密度梯度的等离子体中的自调制进行了数值模拟和实验研究，模拟结果与文献[F. Braunmller，T. Nechaevaet al.（Awake Collaboration），Phys. Rev. Lett. 125，264801（2020）PRLTA 00031 -900710.1103/PhysRevLett.125.264801]：在负梯度的情况下，调制聚束的电荷低于在正梯度的情况下。此外，聚束调制频率随梯度变化。模拟结果表明，尾流场相对于相对论质子沿着的退相是电荷损失的主要原因。调制频率的研究揭示了自调制过程沿着等离子体演化的细节。特别是对于负梯度，跨聚束的时间分辨图像的调制频率指示质子离开尾场的沿着等离子体的位置。模拟和实验结果非常吻合。
We present numerical simulations and experimental results of the self-modulation of a long proton bunch in a plasma with linear density gradients along the beam path. Simulation results agree with the experimental results reported [F. Braunmller, T. Nechaevaet al.(AWAKE Collaboration), Phys. Rev. Lett. 125, 264801 (2020)PRLTAO0031-900710.1103/PhysRevLett.125.264801]: with negative gradients, the charge of the modulated bunch is lower than with positive gradients. In addition, the bunch modulation frequency varies with gradient. Simulation results show that dephasing of the wakefields with respect to the relativistic protons along the plasma is the main cause for the loss of charge. The study of the modulation frequency reveals details about the evolution of the self-modulation process along the plasma. In particular for negative gradients, the modulation frequency across time-resolved images of the bunch indicates the position along the plasma where protons leave the wakefields. Simulations and experimental results are in excellent agreement.
