Role overview
Dense tracking environments in experiments at CERN's High-Luminosity LHC and future FCC experiments require increased use of timing information in addition to the position measurements provided by pixel detectors.
This adds an extra dimension to the available information and is essential for mitigating pile-up effects at high luminosities. of CERN
