Operation experience with highly irradiated ATLAS FE-I3 SingleChipAssemblies — Claus Gößling, •Silke Herbst, Reiner Klingenberg, Daniel Münstermann, André Rummler, and Tobias Wittig — TU Dortmund, Experimentelle Physik IV, D-44221 Dortmund

ATLAS is a multi-purpose detector at the Large Hadron Collider (LHC). After the planned upgrade to SuperLHC, the pixel detector as the innermost part of the ATLAS tracker will have to withstand particle fluences of up to 2·10¹⁶ n_eqcm⁻² and ionizing doses of up to 800 MRad.

We operated silicon pixel sensors with FE-I3 readout electronics (SingleChip-Assemblies) irradiated with 24 MeV protons and reactor neutrons up to doses of 300 MRad and investigated the performance of the SingleChip-Assemblies after irradiation. The observed changes of the readout chip’s behaviour and the necessary modifications of the FE-I3 tuning will be presented.
