Summary
In the coming years, LHC will be upgraded step by step to reach a total integrated luminosity of few thousand inverse femtobarns. The experiments at LHC are also planning upgrades, among them replacements of their pixel detectors.
ATLAS will follow a two-step strategy with the installation of a new insertable b-layer (IBL) in 2016 with a radius of only 32 mm from the beam. Planar, 3D and diamond sensors are under consideration as IBL sensors; sufficient radiation hardness for a fluence of 5E15 neq/cm^2 was specified. The pixel sensors for the innermost layer at SLHC will even have to withstand up to 2E16 neq/cm^2.
ATLAS SingleChip-Assemblies based on the FE-I3 readout chip have been irradiated with reactor neutrons in Ljubljana to fluences up to 2E16 neq/cm^2. First measurements obtained with a Sr-90 source in the lab will be presented. The collected charge will also be compared to preliminary testbeam results.
Furthermore, a brief status update on the irradiation and testbeam measurements of samples from the "common RD50/PPS" and the "thin n-bulk PPS" productions with CiS will be given.
