超冷中性等离子体的微波诊断

Microwave Diagnostics of Ultracold Neutral Plasma

Ronghua Lu, Li Guo, Shensheng han

摘要:

提出了一种利用微波辐射诊断超冷中性等离子体的方法。计算了超冷中性等离子体的微波散射。得到了简单的计算公式,并指出当$ω\ggω_{pe0}$时,超冷中性等离子体的偶极辐射功率不依赖于密度分布$n_e(r)$和$ω$,而依赖于总电子数$N_e$。该方法提供了等离子体的$N_e$信息,并由此得到了等离子体的三体复合率,这在超冷中性等离子体的研究中是非常重要的。

英文摘要:

We suggest an approach for using microwave radiation in diagnostics of ultracold neutral plasma. Microwave scattering from ultracold neutral plasma is calculated . Simple formulations are get and indicate that the dipole radiation power of ultracold neutral plasma does not depend on density profile $n_e(r)$ and $ω$ when $ω\ggω_{pe0}$, but on the total electron number $N_e$. This method provides the information of $N_e$ and from which we can get the three body recombination rate of the plasma, which is extremely important in the researches of ultracold neutral plasma.
