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.
