Abstract

Full-size and miniature Large Hadron Collider (LHC) detectors fabricated on 4- and 6-in wafers have been processed using oxygenated and nonoxygenated substrates. After irradiation to 3×10¹⁴/cm² with 24-GeV/c protons and short-term annealing, these detectors have been studied in terms of their charge collection as a function of depletion voltage with LHC-speed analog electronics. Results are presented indicating the degree of improvement seen in terms of the main operationally significant parameter, namely, the bias voltage needed for a given signal read out with fast electronics
