Abstract :
The standards report the development of a second 199Hg + linear ion trap (LIT) based frequency standard to provide a capability for measuring stability beyond all existing frequency standards. Increased signal using a second light collection system together with a previously demonstrated atomic line Q ≈ 2 × 10 12 yields a performance better than σy (τ = 7 × 10-14/τ1/2). Sensitivity to the leading perturbations are measured to identify regulation requirements to obtain a stability of 10-16
