Abstract
A fast track reconstruction algorithm for the ATLAS second level trigger is presented. The timing performance (3.5 ms for a jet reconstruction at low luminosity) is satisfactory; the transverse impact parameter resolution (75 mum) is sufficient to perform an on-line b-tagging, and the full three-dim ensional reconstruction produces good seeds for more sophisticated track se arches.
