The next big upgrade of the LHC machine will deliver highest instantaneous luminosities ever achieved in hadron colliders, at the highest center-of-mass. This incredible amount of data collected at the High-Luminosity LHC has the potential to shed light on some of Nature’s deepest mysteries. New detector technologies need to be developed in order to maximally exploit the potential of the HL-LHC. Reconstructing remnants of interactions at collider experiments traditionally relies on measurements of particles’ energy (p, E) and position (x) using calorimeters and tracking detectors. The last remaining component of the particle’s coordinate, time t, has not generally been utilized to its full potential. Both CMS and ATLAS collaborations are now working on equipping the upgraded experiments with detectors capable of stamping charged particles with ~30 ps precision. I will briefly describe the technology used for these detectors, and describe the impact that they promise to have on the physics program at CMS.
