Abstract:

The purpose of this work is to develop techniques to overcome the fundamental limits of present frequency standards--the second and residual first-order Doppler shifts. To this end we study suitable frequency reference transitions in ions which are stored on electromagnetic traps and cooled by radiation pressure to 1K. Keywords include Atomic spectroscopy Doppler narrowing Doppler shifts frequency standards high resolution spectroscopy ion storage laser spectroscopy Penning trap and radiation pressure.
