2017年,AWAKE展示了来自CERN超级质子同步加速器(SPS)的400 GeV质子束的种子自调制(SSM)。由于SSM偏转的质子的角分布是一个定量测量的过程,这与模拟的二维(轴对称)粒子在细胞的代码LCODE。对于1011和3×1011粒子之间的束群,各种等离子体密度梯度(−20 <$20%)和两种等离子体密度(2 × 1014 cm −3和7 × 1014 cm −3),都实现了一致性。只有在足够宽的模拟箱(至少五个等离子体波长)的情况下,才能达成协议。
In 2017, AWAKE demonstrated the seeded self-modulation (SSM) of a 400 GeV proton beam from the Super Proton Synchrotron (SPS) at CERN. The angular distribution of the protons deflected due to SSM is a quantitative measure of the process, which agrees with simulations by the two-dimensional (axisymmetric) particle-in-cell code LCODE. Agreement is achieved for beam populations between 1011 and 3×1011 particles, various plasma density gradients (−20 ÷ 20%) and two plasma densities (2 × 1014cm−3 and 7 × 1014cm−3 ). The agreement is reached only in the case of a wide enough simulation box (at least five plasma wavelengths).
