Recent advances in laser-plasma accelerators have made possible the production of high-power beams with very low divergence. In this paper, the carbon heavy-ion beam was used to provide optimal conditions for the ignition of P– $$^{\mathrm {11}}$$ 11 B clean fuel pellets using the Deira-4 simulation code. The calculations showed that generating maximum ion heating of about 140 keV requires a laser with an intensity of $$10^{\mathrm {21}}\,\hbox {W}/\hbox {cm}^{\mathrm {2}}$$ 10 21 W / cm 2 and a radiation time of 20 ps, which provide medium heating conditions for ignition.

无中子聚变反应中重离子束的能量沉积

激光等离子体加速器的最新进展使得产生发散度非常低的高功率光束成为可能。在本文中，碳重离子束用于使用 Deira-4 模拟代码为 P–$$^{\mathrm {11}}$$ 11 B 清洁燃料芯块的点火提供最佳条件。计算表明，产生约 140 keV 的最大离子加热需要强度为 $$10^{\mathrm {21}}\,\hbox {W}/\hbox {cm}^{\mathrm {2}} 的激光$$ 10 21 W / cm 2 和20 ps的辐射时间，为点火提供中等加热条件。
