| Résumé | Improved functionality and accuracy of the NRC Sr⁺ single trapped ion 445-THz standard is described. Absolute frequency stabilization of all laser sources has been achieved together with loading of the ion trap using photo-ionization methods. An Erbium fiber laser based frequency comb is used to directly measure the 445-THz clock frequency. A 9 hr preliminary measurement was performed with statistical uncertainty of 1.4 Hz (3×10⁻¹⁵) in excellent agreement with a previously reported value in 2005. A new endcap trap with probing and micromotion correction in three dimensions has been assembled and will have uncertainties approaching 10⁻¹⁷ in the near future. |
