2. 2 April 2, 2004, Athena tutorial, FZU, PragueZdeňka Broklová History December 03: - familiarize with Athena, simulations and NOVA database January 04: - creation of endcap modules and testbeam geometric setup February 04: - simulation and digitization March 04:- reconstruction geometric setup  G4  hits  digits  spacing  tracking

3. 3 April 2, 2004, Athena tutorial, FZU, PragueZdeňka Broklová SCT_GeoModel prepare new geometric description of endcap modules –more realistic hybrid shape –two sensors on each side –adding subspines –improved precision of description –set right materials now it is integrated in SCT_GeoModel (made by Grant Gorfine) Contents: - geometric parameters of all SCT components - set materials - properties of sensitive wafers - whole SCT description

14. 14 April 2, 2004, Athena tutorial, FZU, PragueZdeňka Broklová Conclusion whole sequence seems to be working (in athena 7.5.0, 7.7.0 and 8.0.0) standard packages are being used we know how to run it and make changes (e.g. how to put results into text file, histograms or ntuples) up to now it hasn’t been much stable (due to massive development) hopefully it will be better Our status and results are summarized on http://ific.uv.es/~cescobar/simulation.html

15. 15 April 2, 2004, Athena tutorial, FZU, PragueZdeňka Broklová Conclusion II. We are about to start completing physical tasks and answering physical questions like standard testbeam analysis (noise occupancy, efficiency, fake tracks, etc) Practicle guides and examples for newcomers are on our web We are able and willing to share our experience with others (feel free to contact us) Our status and results are summarized on http://ific.uv.es/~cescobar/simulation.html
