为了研究超强激光等离子体相互作用中的离子加速，我们测量了靶体中D-D离子核反应的中子谱。50-100TW/0.5-1 ps的激光以不同的激光偏振和强度斜照射变性塑料固体目标。中子能谱与三维蒙特卡罗模拟结果的对比表明，在任意偏振方向上，离子在近目标法向上均有加速，且离子能量随激光强度的增加而增加。
In order to study the ion acceleration in ultra-intense laser plasma interactions, we measured neutron spectra from the D-D ion nuclear reactions in the target. 50-100TW/0.5-1 ps laser light irradiated obliquely dueterated plastic solid targets with different laser polarizations and intensities. Comparing the neutron spectra with the 3D Monte-Carlo simulation indicates ion acceleration in the near target normal direction at any polarization and increases in the ion energy with laser intensity.
