摘要

利用线性流体理论推导了热等离子体负载自由电子激光器的色散方程。详细分析了该热等离子体自由电子激光器的特性。研究了等离子体密度和等离子体温度对FEL生长速率的影响。我们发现存在一个最佳的等离子体温度，在这个温度下，FEL的生长速度可以得到显著提高。随着等离子体密度的增加，FEL的生长速率降低。

The linear theory of thermal plasma free-electron laser

The dispersion equation of thermal plasma-loaded FEL is derived employing linear fluid theory. The characteristic of this thermal plasma FEL is analyzed in detail. FEL growth rate varying with plasma density and plasma temperature is investigated. We find there is an optimum plasma temperature where FEL growth rate can be enhanced considerably. The FEL growth rate is decreased accompanying plasma density rising.
