The LHC is foreseen to be upgraded to the High-Luminosity LHC HL-LHC). This will result in higher particle rates and radiation doses. The ATLAS experiment plans to replace its inner tracking detector by a new all-silicon tracker which is based on the concept of modularity. For the new silicon strip tracker a large prototyping and evaluation campaign is ongoing. Many modules of different types were built and tested both in the laboratories and in test beams. In the following
first results obtained in test beams are presented. Both mini and full-size modules for the central and forward regions were tested before and after irradiation to fluences as expected at the HL-LHC.
