Abstract

This article describes the first operational results from the extended linear ion trap frequency standard now being developed at JPL. This new design separates the state selection/interrogation region from the more critical microwave resonance region where the multiplied local oscillator (LO) signal is compared to the stable atomic transition. Hg ⁺ ions have been trapped, shuttled back and forth between the resonance and state selection traps. In addition, microwave transitions between the Hg⁺ clock levels have been driven in the resonance trap and detected in the state selection trap
