Light weight Rubidium-Metal Vapor Circulating System

Frederick T. Elder & Associates(FTEA) proposes an approach to the development of a closed-cycle Helium-Rubidium(He-Rb) circulator that allows for FTEA to ensure safety throughout the project, to manufacture a prototype at a reasonable cost using mostly commercial components if selected for Phase II, and to meet or exceed the requirements outlined in the solicitation. FTEA has considered existing Diode-Pumped Alkali Laser technologies, rubidium chemical compatibility, low-leak fittings, contamination resistant and seal-less pumps, and contacted subcontractors who have offered their experience and future assistance. By choosing a design that does not require dynamic or rotating shaft seals, FTEA will eliminate the accidental release of hazardous material and the contamination of the supplied He-Rb mixture. The selection of commercially available hardware allows FTEA to apply our past experiences with hazardous chemicals and custom test apparatus towards the requirements of the MDA while minimizing the cost and development time for the finished product.
