    The scientists at DARPA will next month detail a new program the group hopes will develop small, portable, battery-powered atomic clocks with stability, repeatability, and environmental sensitivity 1,000 times better than the current generation of atomic clocks.

    On Feb. 1 DARPA will detail the Atomic Clocks with Enhanced Stability (ACES) program which will aim to develop clocks that must fit into a package about the size of a billfold and run on a quarter-watt of power. “Success will require record-breaking advances that counter accuracy-eroding processes in current atomic clocks, among them variations in atomic frequencies that result from temperature fluctuations and subtle frequency differences that can occur if the power shuts down and then starts up again,” DARPA stated.
