ATLAS silicon microstrip detector system (SCT)

The SCT together with the pixel and the transition radiation tracker systems and with a central solenoid forms the central tracking system of the ATLAS detector at LHC. Series production of SCT Silicon microstrip sensors is near completion. The sensors have been shown to be robust against high voltage operation to the 500 V required after fluences of 3×1014 protons/cm2. SCT barrel modules are in series production. A low-noise CCD camera has been used to debug the onset of leakage currents.
