Trapped Ions, Laser Cooling, and Better Clocks

D. J. Wineland 1

1 Research physicist in the Time and Frequency Division of the National Bureau of Standards, Boulder, Colorado 80303.

Ions that are stored in electromagnetic "traps" provid the basis for extremely high resolution spectroscopy. By using lasers, the kinetic energy of the ions can be cooled to millikelvin temperatures, thereby suppressing Doppler frequency shifts. Potential accuracies of frequency standards and clocks based on such experiments are anticipated to be better than one part in 1015.
