Description
To extend the physics reach of the LHC, upgrades to the accelerator are planned which will increase the peak luminosity by a factor of 5 to 10. This will increase the occupancy and the radiation damage of the inner trackers.To cope with the elevated occupancy, the ATLAS experiment plans to introduce an all-silicon inner tracker with the High Luminosity-LHC (HL-LHC) phase-II upgrade. This translates to an increase in area covered by pixels from 2 m2 to somewhere between 5-7 m2 in the current ATLAS pixel baseline layout. This increase necessitates the need for more cost effective pixel modules. Work will be shown on large area quad n-in-p geometry hybrid modules for use at large radii in the outer pixel layers and disks, as well as small single devices with standard and increased resolution along the R phi direction will be discussed, featuring test beam, lab measurements and simulations.
