| Sumario: | The High Luminosity upgrade of the CERN Large Hadron Collider will be able to reach a peak instantaneous luminosity of 5 × 1034 cm−2 s−1. The innermost detectors of the CMS and ATLAS experiments will have to cope with unprecedented requirements on radiation hardness. At the end of the operation period, radiation levels are expected to reach values above 2.6 × 1016 neq cm−2. Sensors based on 3D pixel technology, with intrinsic radiation tolerance, are the baseline option for the innermost layers of the vertex detectors of several HL-LHC experiments. This article gives an overview of the ongoing characterization of the pixelated 3D sensor technology, their performance and their current development status for tracking on radiation harsh environments. |
