Abstract :
We describe frequency stability measurements of two Hg-ion clocks based upon linear 12-pole shuttle ion traps. The inter-comparison was carried out over several multi-day intervals with the short-term stability of each clock better than 2×10-13 at 1 second. Longer-term stability as good as 3×10-16 was demonstrated for these clocks.
