Abstract

The ATLAS experiment, at the Large Hadron Collider, will incorporate discrete, high-resolution tracking sub-systems in the form of segmented silicon detectors with 40MHz radiation-hard readout electronics. In the region closest to the pp interaction point, the thin silicon tiles will be segmented into a pixel geometry providing two-dimensional space-point information. The current status of the ATLAS pixel project will be presented with an emphasis on the performance of the front-end electronics and prototype sensors.
