  • Abstract
    A frequency standard for the USNO based on mercury ions in a Linear Ion Trap is operational. Initial measurements of the new standard LITS-3 against an active hydrogen maser gives a fractional frequency stability of σy(τ)=7.5×10-14/τ 1/2 for measuring intervals up to 10,000 seconds. Stability measurements for longer averaging intervals against another ion trap standard have commenced
