NIST atomic radio headphones

Caption

Copper “headphones” boost the sensitivity of NIST’s atomic radio receiver, which is composed of a gas of cesium atoms prepared in a special state inside the glass container. When an antenna located above the setup sends down a radio signal, the headphones boost the strength of the received signal a hundredfold.
