Abstract
Silicon pixel sensors for the ATLAS Pixel Detector have been successfully d eveloped. The main attention for the design was given to survivability in t he harsh radiation environment of LHC up to a fluence of 10(15)n(eq)/cm(2) during 10 years of operation. This leads to the need of long term operation at several hundreds of volts, partially depleted while maintaining good ch arge collection, small cell size and thin sensors reducing the multiple sca ttering. Additionally, a bias grid for testing the sensors before assembly under realistic bias conditions is implemented to allow a quality assurance . (C) 2001 Elsevier Science B.V. All rights reserved.
