FEL用于阈能反应分子法激光分离铀同位素研究

A POTENTIAL APPLICATION OF FREE ELECTRON LASER -Laser-based uranium enrichment(threshold reaction method in molecular forms)

提出了自由电子激光 ( FEL)的一种可能应用。指出静电电子加速器驱动的 FEL技术目前已有能力满足阈能反应分子法激光分离铀同位素的要求。阈能反应分子法由于只需一次激光激发 ,因此从原理上讲 ,它的一次分离系数很高 ,优于原子法与其他分子法 ,在高浓铀小规模 ( 1 0 kg/ a)生产中有其可行性。

In this paper a potential application of free electron laser was pointed out. Threshold chemical reaction method (TCR) for laser-based separation of uranium isotopes in molecular forms has advantage of avoiding second excitation over the atomic and other molecular forms. It has larger single-pass separation factor than the atomic and other molecular forms in principle. The requirements for laser adopted in the method can be met by the available technology of FEL driven by electro-static accelerator. It is able to product highly enriched uranium in a small scale of 10kg per year using TCR.
