Some recent developments show that a neutral-particle accelerator (e.g., a molecular accelerator) can be an important tool not only to the chemical investigator but may also have potential use in an entirely new field namely solid-state device fabrication. Experimental evidence of alternate gradient focusing of neutral particles has already been reported by one of the authors elsewhere. This paper now presents a theoretical analysis and considers the possibilities of extending the work for construction of a neutral-particle accelerator. An ammonia molecular-beam is considered as an example. A particular advantage in this case is that the transported molecular beam can be analyzed in a conventional superheterodyne set up.
