Trapped ions
Revision as of 17:36, 7 February 2019 by imported>Kot
Trapped ions are widely used for the optical clocks, due to their long live times in the trap. Two types of trap exist: Penning and Paul. The first type is less used, as it requires a big magnetic field, small fluctuations could change atom position inside the trap. Paul trap is based on an oscillating electric field, the depth of created trap could easily exceed 1eV.
Ion clocks
The best results with ion clocks are achieved with Al ions.
- In Wineland group a fractional frequency difference (-1.8±0.7)x10-17
- Later work, where authors achieved higher instability 3x10-18 [1]
