Abstract :
This paper introduce three main technologies in our coherent population trapping clock. The rubidium vapor cell is fabricated by glass-silicon anodic bonding techniques. We use two different buffer gases (Ar and Ne) that produce opposite shift rates to reduce the dependence of the clock frequency stability on the temperature stability of the atoms. We use the ceramic-filled coaxial resonator as the RF resource.
