Abstract
Atomic vapor laser isotope separation has been studied at the Institute for Advanced Studies for nuclear purposes since 1982, and recently it has been questioned about its potentialities for the aerospace area. Many applica- tions from nuclear propulsion to electricity generation and space navigation have been found, which justify the study of isotope separation for aerospace applications. 2ne of the Ney process, and the orst step for atomic vapor laser isotope separation, is the production of a neutral vapor jet. This paper discussed the potentiality of using laser ablation as a tool to generate neutral metal vapor jet for isotope separation purposes. The basis for the discussion is a set of experimental results obtained at the Institute for Advanced Studies. The experiments were described, the results were analyzed using basic theoretical treatment found in the literature, and it was concluded that laser ablation is a potential tool for the generation of a neutral vapor jet for atomic vapor laser isotope separation purposes.
Highlights
Both stable and radioactive isotopes have many important applications in the aerospace area
Lithium niobate is an optical material broadly used in electro-optics devices and circuits used in inertial optical platforms: lithium niobate with low content of 6Li is shown to be less sensitive to cosmic radiation and to have a longer operational life than the ordinary LiNb (Riley, 1999)
This paper presents an experimental study in order to investigate the assumption that laser ablation can be used to prepare a neutral atomic jet for AVLIS purposes
Summary
Both stable and radioactive isotopes have many important applications in the aerospace area. Short-laser pulses can remove a fraction of a target surface, generating a plume made of neutral atoms, ions, clusters, and GURSOHWVRIOLTXL¿HGPDWHULDO $PRUXVRet al., 1999; Capitelli et al, 2004; Noll, 2012). The interest for isotope separation is far from the target surface, where the plume is not collisional anymore and most of the ions and neutral atoms have decayed to the ground or metastable states. Under our experimental conditions, laser ablation is a potential method for neutral jet production for further isotope separation, at least when tiny amounts of material are desired.
