|Abstract:||The aim of this SBIR program is to develop a CNT based gas ionization source to replace radioactive 63Ni beta emitter sources used in ion detection instruments, cost effectively and without performance offsets. In Phase I, ANI worked with development partner Sionex, Inc. to establish proof of concept for basic functionality of the CNT ion source technology, demonstrating an ionic current at atmospheric pressure exceeding the capacity of a 10 mCurie 63Ni beta source, with continuous operation for over 300 hours. In Phase II, ANI and Sionex will develop a complete Differential Mobility Spectrometer (DMS) with an integrated CNT ion source. Materials, components and device designs will be refined and optimized. The CNT ion source components will then be integrated into DMS ion detection device prototypes and field tested in practical applications. Successful completion of the Phase II effort will result in a compact, non-radioactive CNT ion source suitable for use in DMS and other analytical instruments, lowering their cost of ownership. At the end of Phase II, a complete working prototype DMS will be delivered to the government to conduct further testing.|
