Description
In a beamtest at CERN H2 the behaviour of irradiated and non-irradiated full-size AC-coupled strip detectors made of n-type magnetic Czochralski silicon was investigated. The sensors of the size of 4x4 cm^2, 300µm thickness with 768 strips and 50µm pitch had been produced at the Helsinki Institute of Physics. After the qualification, the sensors were irradiated with fluences between 10^14/cm^2 and 10^15/cm^2 and were tested again. Modules had been built with irradiated and non-irradiated sensors and APV electronics. The sensors' performances concerning mainly signal/noise, efficiency and resolution were tested with the help of the silicon strip detector based beam telescope SiBT. The beamtest and the results will be presented.
