摘要

分析估算和数值模拟被用来审查独立激光簇和激光簇等离子体焦点体积中核反应产物的产量。研究表明，短强激光脉冲的圆极化会产生平均磁场，使焦点体积的等离子体不会横向膨胀。在某些条件下，等离子体寿命的延长会导致 Li(D, n)8Be 反应中的中子产率显著增加（最多增加一倍），而在没有磁场的情况下，等离子体加热则是通过线性偏振激光脉冲进行的。

Increased Nuclear Reaction Yields in Cluster Targets Irradiated with Circularly Polarized, Short and Intense Laser Pulses

Analytical estimates and numerical simulation were used to review the yield of nuclear reaction products in a separate cluster and in the focal volume of laser cluster plasma. The circular polarization of a short intense laser pulse is shown to produce an average magnetic field that keeps the plasma of the focal volume from transverse expansion. An extension of plasma lifetime results under certain conditions in a significant (up to double) increase in neutron yield in the Li(D, n)⁸Be reaction compared to plasma heating by a linear polarization laser pulse when the magnetic field is absent.
