Abstract:
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.
