A team of microelectronics engineers from three IN2P3 laboratories (1) has developed and tested two very high precision clock generators. These components will be used to beat the time in the detectors of the future high-luminosity collider at CERN (HL-LHC) in order to time with 2 picoseconds precision all the events that will occur inside. This 4th “temporal” dimension, which will enrich the data, will improve the precision and quality of the measurements while reducing the flow of data to be processed.
