论文摘要
偏振氘 - 三位体（DT）融合血浆的自旋转运方程是用密度基质配方得出的，该密度矩阵配方用于研究间接驱动的惯性惯性限量融合融合期间极化DT-GAS填充靶标的流体动力学。通过强型自生成的磁场对DT离子的去极化可以通过自旋传输方程捕获。中子产率，角分布和中子束极化是从目标内爆的三维自旋传输流体动力学模拟获得的。仿真结果表明，极化靶标的优化的自旋对齐可以减少DT离子的去极化，并在间接驱动的内爆中通过极性模式不对称诱导的中子束。
The spin transport equations for polarized deuterium-tritium (DT) fusion plasma are derived with the density matrix formulation, which are used to investigate the hydrodynamics of polarized DT-gas-filled targets during indirectly driven inertial confinement fusion implosions. The depolarization of DT ions by strong self-generated magnetic fields can be captured by the spin transport equation. The neutron yield, angular distribution and neutron beam polarization are obtained from three-dimensional spin transport hydrodynamics simulations of the target implosions. The simulation results indicate that an optimized spin alignment of the polarized target can reduce the depolarization of DT ions and the neutron beams induced by polar mode asymmetries in indirectly driven implosions.
