Abstract:
In order to harvest the maximum physics potential of the CERN Large
Hadron Collider (LHC), an upgrade program is underway to significantly
increase the LHC luminosity (High Luminosity LHC). This will result in
unprecedented radiation levels, exceeding the LHC fluences by roughly an
order of magnitude. Due to the radiation damage limitations of the
silicon sensors presently used, the physics experiments will require new
tracking detectors for HL-LHC operation. ATLAS, CMS and LHCb, have
developed extremely radiation hard silicon sensors to be employed on
the innermost layers. In addition timing detectors implementing
innovative silicon sensors will be used to correctly disentangle
spatially overlapping events, aiding the tracker devices in the correct
reconstruction of each event. The prospects of creating a new family of
silicon sensors merging excellent position and timing resolution for
particle tracking in four dimensions will be discussed.
