Daniel Valuch, of CERN, invents and evaluates the outcome of adding a “Chain Controlled Oscillator” (a.k.a. CCO) into a highly-precise Elektročas HH3 clock fitted with an Invar pendulum.

The CCO mechanism itself is tied into a cesium atomic clock, enabling the outfitted Elektročas HH3 to be regulated to stratum 1 levels of accuracy in near realtime.
