In phase II the LHC will be upgraded to the High Luminosity LHC. To fulfill the increased particle flux and higher instant luminosity, the ATLAS experiment will be equipped with a new Inner Tracker (ITk). Because of the close position to the beam line, the pixel modules of the ITk are exposed to high radiation. Planar n-in-n silicon sensors with different pixel implantations have been designed and prototype sensors have been irradiated in test facilities to simulate the radiation damage. The track recognition efficiency of the different pixel designs are studied by analyzing test beam data. For this analysis the software framework TBMon2 is used. A new analysis extention ''EfficiencyVsGeometry'' was developed to receive detailed results for different parts of the sensor. In this talk the results of non-irradiated sensors and irradiated sensors with either protons or neutrons are presented.
