Abstract

We are reporting laser enhanced chemical reaction for the formation of LiH inside crossed arms heat pipe oven that may be aimed towards the laser enrichment of the isotope of interest. In addition, an interesting feature of particle formation in the crossed arms region of the heat pipe oven (HPO) is presented. The temperature gradient between the cold and hot parts across the crossed arms region causes the convection currents to develop, that results in the formation of fog due to the lithium clusters in the presence of helium as buffer gas. When helium gas is replaced by hydrogen, large size particles were observed through naked eye from the scattering of laser light passing through the HPO. At the interface between the localized cold and hot regions of the convection currents, the density of LiH molecules increases up to certain limit where they condense into bigger particles. Gravity forces the particles to fall down and they are forced to follow the convection current flow path.
