Abstract
This article reports on the performance of a field emission array characterized for the purpose of replacing the filament in a trapped ion frequency standard. This dark electron emitter eliminates the need for the interference filter currently used in the trapped ion standard. While reducing the filament’s unwanted light, this filter causes a significant reduction in the signal. The magnetic field associated with the filament is also eliminated, thus potentially improving the present stability of the trapped ion standard, The operation of the filament in the present system is described, as well as the associated concerns. The cathode considered for the filament’s replacement is then described along with the experimental system. Experimental results, observations, and conclusions are presented.
