Czochralski silicon sensors: Status of development

Tracker systems based on silicon detectors are one of the possible choices for experiments at the future upgrade of the Large Hadron Collider (LHC) the Super-LHC (SLHC). Optimization of material and detector design are key factors to develop ultra radiation hard silicon devices. Most advanced research activity in this field identified Magnetic Czochralski (MCz) material as a candidate for the processing of such a detectors. aper summarizes more relevant results achieved by the CERN RD50 and SMART INFN collaborations. Recent studies on test structures and micro-strip detectors processed on MCz material, n-type and p-type doped, and the radiation hardness performance after heavy irradiation tests are described. collection from particles has been evaluated on diodes and micro-strip detectors and extrapolation of tracking performances up to the fluence expected at SLHC has been studied. Promising results in terms of radiation hardness parameters have been achieved.
