    ASTRA, a Reconstruction Algorithm for the Silicon Detectors

    No full text
    This note describes ASTRA, which is an acronym for Atlas Silicon detector Track Reconstruction Algorithm. By design, ASTRA provides fast and efficient reconstruction of Inner Detector tracks using the Pixel and SCT subdetectors. A detailed description of the track-recognition procedure is given. The application to a simulated H->bb event at high luminosity is shown

    Three dimensional cleaning of data from HEP events

    No full text
    In large HEP detectors typically a very high number of 3D hits is recorded simultaneously. We present a fast method to clean these data from unwanted hits, which significantly improves event visualisa tion. The accepted hits can be grouped, each group containing practically all hits of one or a few single tracks. The execution time is proportional to the number of hits
