|Abstract:||In the recent past, government agencies from the US and other foreign countries have recognized the problem of orphaned radioactive sources worldwide. Such sources pose a security risk in the form of potential material for a "dirty bomb" or other illicit applications. We propose to replace Ni-63 beta emitters with a carbon nanotube based electric field ionization source. This CNT-based ionization source will be useful for a whole class of devices that currently use radioactive materials for gas ionizers. This CNT gas ionizer will be a nearly one-for-one replacement for the Ni-63, requiring only minor additional driver electronics to operate the source. The CNT ionizer will operate over a wide temperature range (-50 degree C to +100 degree C is expected). The source can be designed to fit almost any size and shape needed for the analytical instrument.|
