 NIST: Time and Frequency Division - Division 847
The Time and Frequency Division, part of NIST's Physics Laboratory, maintains the standard for frequency and time interval for the United States, provides official time to the United States, and carries out a broad program of research and service activities in time and frequency metrology.
NIST researchers have demonstrated a minuscule atomic clock with inner workings about the size of a grain of rice and potential applications in atomically precise timekeeping in portable, battery-powered devices for secure wireless communications, more precise navigation, and other applications.
NIST researchers are also demonstrating the potential to fabricate and assemble the physics package using the low-cost, mass-production techniques used to make semiconductor devices, which should eventually lead to a complete atomic clock about 1 cubic centimeter in size (about the size of a pencil eraser) powered by a battery.
