Cooled Ion Frequency Standard

Abstract

The purpose of this work is to develop techniques to overcome the fundamental limits of present frequency standards--the second order and residual first-order Doppler shifts. To this end suitable frequency reference transitions are studied for ions which are stored on electromagnetic traps and cooled by radiation pressure to less than 1K. Keywords: Atomic spectroscopy; Doppler narrowing; Doppler shifts; Frequency standards; High resolution spectroscopy; Ion storage; Laser spectroscopy; Penning trap; Laser cooling.
