Abstract :
We describe the development of a small Hg+ ion clock suitable for space use. A small clock occupying 1-2 liters volume and producing stability of 10-12/√τ would significantly advance the state of space-qualified atomic clocks. Based on recent measurements, this technology should produce long-term stability as good as 10-15.
