Frontier tracking detectors for HL-LHC

The High-Luminosity program of the LHC poses unprecedented challenges for the tracking systems of ATLAS and CMS in terms of radiation tolerance and instantaneous particle rates. Thanks to use of advanced technologies and novel solutions, the future trackers are expected to meet those requirements, along with improved tracking performance and important additional functionalities. In parallel with the development of the next trackers, R&D; is continuing to prepare the ground for further novelties beyond the HL-LHC era.
