纯热传导冷却产生软X射线激光

Soft-X-ray laser in plasma cooled only by themal conduction

本文通过n_e=1×10^(19)cm^(-3)的热等离子体,在纯热传导冷却机制下的计算,得到了等离子体温度的时空变化,并运用碰撞-辐射模型计算了在这种条件下,类锂铝离子4f-3d,5f-3d跃迁的增益系数,计算表明:只要有合适的初始条件,用纯热传导冷却机制,也能产生软X射线激光增益.

Through the calculation of plasma with electron density of 1 × 1019 cm-3, and cooled only by electron thermal conduction, we got the plasma parameters varied with time and space. Under this contition, we calculated the gains of 5f-3d and 4f-3d of Li-like Al ions using C-R model. It is shown that once there are suitable initial plasma conditions, the soft-X-ray gains can be produced in plasma cooled only by thermal conduction.
