Laser Cooled 9Be+ Accurate Clock,
NATIONAL BUREAU OF STANDARDS BOULDER CO TIME AND FREQUENCY DIV
The use of laser cooled stored ions in an atomic frequency standard has the potential of very high accuracy because Doppler effects are greatly suppressed. A clock based on the ground-state hyperfine transition in 201Hg has potential accuracy and stability exceeding 1 part in 1015. However, laser cooled 9Be ions are experimentally easier to obtain. Therefore a 9Be based frequency standard is investigated in order to study the generic problems of laser cooled stored ion frequency standards.
