To quantify the mobility degradation caused by ionized impurity scattering as a function of fluence and to obtain a qualitative understanding of the diode’s electrical performance, current-voltage characteristics were measured for fluences ranging from $9 \times 10^{14}$ to $1 \times 10^{18}\,n_{eq}/$cm$^2$ at various temperatures. These measurements are compared to TCAD simulations using different radiation-damage models to evaluate their ability in reproducing the observed currents at such extreme fluences, and to gain insight into the underlying physical processes driving these changes..

Current Status of the Phase-2 ATLAS ITk Pixel Detector
/ Martin, Juliette (University of London (GB))
/ATLAS Collaboration
The upgrade of the LHC to the high luminosity LHC (HL-LHC) by the end of this decade will impose significant challenges on the detectors of the LHC experiments. Increased luminosity of up to 7.5 10^34cm^−2s^−1 with up to 200 simultaneous p-p interactions per bunch crossing and foreseen run-times equivalent to up to 4000 fb-1 make it necessary to develop new detectors that can cope with the corresponding radiation damage, occupancy, and bandwidth needs.
