  1. TB Analysis Alessandra Borgia & Marina Artuso VELO Group Meeting, Friday March 6, 2009

  2. Status Report • Writing rootscript to avoid Vetra • Ntuple • Clusters • Histos • Compare old vs. new • Understand/resolve shoulder-issue Alessandra Borgia, SU VELO Meeting, March 6 2009

  3. Important Data Info • 20k evts • First 2 channels of each channel removed • Only considered: • 1 cluster events = cluster per sensor • 1 strip clusters • Beam at top – Sec 3 – Tell1 8 Irradiated • Beam at bottom – Sec 0 – Tell1 Irradiated • Test Module – beam @ Sec 0 – R Sensor only Alessandra Borgia, SU VELO Meeting, March 6 2009

  4. Position of irradiation spots Tell1 8 n-in-p Tell1 5 n-in-n Top • lars config • run over 20000 events Voltages: • 500V on each sensor • 300V on irradiated and 500V on non-irr Beam Bottom Data File: RR-beam-top-larscfg-HV500-HV300-20080627-073545.mdf Alessandra Borgia, SU VELO Meeting, March 6 2009
