  1. TB Analysis Alessandra Borgia & Marina Artuso VELO Group Meeting, Friday March 13, 2009

  2. Status Report • Writing rootscript to avoid Vetra • Ntuple • Clusters • Histos • Compare old vs. new • Understand/resolve shoulder-issue 2/19

  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 @ top –Sec 3– Tell1 8 High Irradiation • Beam @ bottom –Sec 0– Tell1 5 High Irradiation • Test Module –beam @ Sec 0– R Sensor only 3/19

  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 High irradiated and 500V on Low irradiated Beam High Irr Low Irr Bottom Data File: RR-beam-top-larscfg-HV500-HV300-20080627-073545.mdf 4/19

  5. Beam Top: Matched Tell1 5 / 500 V / Rootscript Tell1 8 / 300 V / Rootscript Tell1 5 / 500 V / Gwen’s code Tell1 8 / 300 V / Gwen’s code 5/19

  6. Beam @ Top Tell1 8 / 300V / ADC Distribution 100 to 300 um -100 to - 300 um 300 to 500 um - 300 to - 500 um 6/19

  7. Beam @ Top: Sector 3 Radius (mm) Radius (mm) 7/19

  8. 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 High irradiated and 500V on Low irradiated Low Irr Beam High Irr Bottom Data File: RR-beam-larscfg-HV300-HV500-20080625-114832.mdf 8/19

  9. Beam Bottom: Matched Tell1 5 / 300 V / Rootscript Tell1 8 / 500 V / Rootscript Tell1 5 / 300 V / Gwen’s code Tell1 8 / 500 V / Gwen’s code Entries Entries ADC Cts ADC Cts 9/19

  10. Beam @ Bottom Tell1 5 / 300V / ADC Distribution 100 to 300 um -100 to - 300 um 300 to 500 um - 300 to - 500 um 10/19

  11. Beam @ Bottom: Sector 0 Radius (mm) Radius (mm) 11/19

  12. Test Module (RΦ) Data:Beam @ Bottom = Sector 0 Tell1 8 / R sensor ADC in sectors with Beam 0-green ADC in sectors with NO Beam 1-red, 2-black, 3-blue Entries ADC Cts Data File: RPHI-beam-lars-cfg-HV100-HV100-20080624-080945.mdf 1 Strip Clusters, 1 Cluster events 12/19

  13. Test Module (RΦ) Data:Beam @ Bottom = Sector 0 Tell1 8 / R sensor ADC in sectors with Beam 0-green ADC in sectors with NO Beam 1-red, 2-black, 3-blue Entries ADC Cts Data File: RPHI-beam-lars-cfg-HV100-HV100-20080624-080945.mdf 1 Strip Clusters, Multiple Cluster events 13/19

  14. Test Module (RΦ) Data:Beam @ Bottom = Sector 0 Cluster hits in all Sectors Radius vs. entries in Sector 0 Entries Radius (mm) Data File: RPHI-beam-lars-cfg-HV100-HV100-20080624-080945.mdf 1 Strip Clusters, 1 Cluster events 14/19
