Planar Pixel Sensors for the ATLAS tracker upgrade at HL-LHC

Abstract

The ATLAS Planar Pixel Sensor R&D Project is a collaboration of 17 institutes and more than 80 scientists. Their goal is to explore the operation of planar pixel sensors for the tracker upgrade at the High Luminosity-Large Hadron Collider (HL-LHC). This work will give a summary of the achievements on radiation studies with n-in-n and n-in-p pixel sensors, bump-bonded to ATLAS FE-I3 and FE-I4 readout chips. The summary includes results from tests with radioactive sources and tracking efficiencies extracted from test beam measurements. Analysis results of $2\cdot 10^{16}{\text{n}}_{\text{eq}}{\text{cm}}^{-2}$ and $1\cdot 10^{16}{\text{n}}_{\text{eq}}{\text{cm}}^{-2}$ ($1\text{MeV}$ neutron equivalent) irradiated n-in-n and n-in-p modules confirm the operation of planar pixel sensors for future applications.
