Radiation Hard Strip Detectors for Large Scale Silicon Trackers — •Ladislav Andricek1, Dieter Hauff1, Josef Kemmer2, Peter Lükewille1, Gerhard Lutz1, Hans-Günther Moser1, Rainer Richter1, Tilman Rohe1, Karin Stolze3, and Andreas Viehl2 — 1Max-Planck-Institut für Physik, München, Germany — 2KETEK GmbH Oberschleissheim, Germany — 3CiS e.V., Erfurt, Germany
Major challenges in building silicon strip detectors for future high luminosity experiments are the high radiation level and the huge number of sensors required for the construction of the precision layers of the complete tracking system. Single sided p+n strip detectors for ATLAS SCT designed and fabricated at the MPI Semiconductor Laboratory have been exposed to 3·1014 /cm2 24 GeV protons. The major features of the design, including the biasing technique using implanted resistors, are discussed and results are presented. The technology was transferred to CiS, Germany, a company capable of the desired large scale production. Results of this industrially fabricated sensors look very promising and show the expected radiation hardness. In addition, the recent results using oxygenated material were implemented in this technology. The properties after proton irradiation of oxygenated full size detectors for the innermost layers of the the ATLAS forward region have been studied.
