  • ION TRAP WITH REDUCED RADIO FREQUENCY (RF) CURRENTS USING MULTIPLE FEED PORTS
    Publication number: 20240014023
    Abstract: Various embodiments provide ion traps or systems comprising ion traps that comprise a trapping portion and a radio frequency (RF) border electrode bounding the trapping portion. The RF border electrode comprises or is in electrical communication with a plurality of feed ports. In an example embodiment, the ion trap comprises a plurality of unit cells each comprising a respective trapping portion, a respective RF border electrode bounding the respective trapping portion, and a respective feed port of the plurality of feed ports.

  • Architecture for compact cold atom clocks
    Patent number: 10535980
    Abstract: An atomic oscillator device includes an atomic oscillator, a controlled oscillator, a resonance controller, and a cold-atom clock output. The atomic oscillator comprises a two-dimensional optical cooling region (2D OCR) for providing a source of atoms and a three-dimensional optical cooling region (3D OCR) for cooling and/or trapping the atoms emitted by the 2D OCR. The atomic oscillator comprises a microwave cavity surrounding the 3D OCR for exciting an atomic resonance. The controlled oscillator produces an output frequency. The resonance controller is for steering the output frequency of the controlled oscillator based on the output frequency and the atomic resonance as measured using an atomic resonance measurement. The cold-atom clock output is configured as being the output frequency of the controlled oscillator.
