Low-mode asymmetries represent an important obstacle to achieving high-gain inertial confinement fusion implosions. As a step in learning how to control such effects, an OMEGA experiment with imposed mode 2 laser drive asymmetries was done to study the expected signatures of this type of asymmetry [M. Gatu Johnson et al., PRE 2018]. In the present work, a 3D xRAGE simulation including the stalk mount has been brought to bear on the data from that experiment. Comprehensive comparisons between simulated and measured observables are made. Good agreement between simulated and measured x-ray image-inferred shell trajectories, bang times and neutron emission widths are seen, showing that the hydrodynamics are well captured in the simulation. Asymmetries seen in simulated and measured time-resolved and time-integrated x-ray images and areal densities also compare well, showing impact of both stalk and mode 2. On the other hand, important differences in measured and simulated neutron emission histories, yield, and ion temperature (T_ion) asymmetries are seen, suggesting that the simulation is overestimating shock yield. The results clearly demonstrate the importance of considering all asymmetry sources when interpreting measured signatures of asymmetry.

低模不对称性是实现高增益惯性约束聚变内爆的重要障碍。作为学习如何控制这种效果的一个步骤，我们进行了具有强制模式2激光驱动不对称性的OMEGA实验，以研究这种不对称性的预期特征。Gatu Johnson等，PRE 2018]。在当前的工作中，已将包括茎杆支架的3D xRAGE仿真用于该实验的数据。进行了模拟观测值和测量观测值之间的全面比较。可以看到模拟和测量的X射线图像推断的壳轨迹，爆炸时间和中子发射宽度之间的良好一致性，表明在模拟中很好地捕获了流体动力学。Ť_离子）的不对称被看见，这表明仿真高估休克收率。结果清楚地说明了在解释测得的不对称特征时考虑所有不对称源的重要性。
