  1. TB Analysis Alessandra Borgia & Marina Artuso VELO Group Meeting, Friday April 3, 2009

  2. Important Data Info • 20k evts • First 2 channels of each channel removed • ONLY considered: • 1 cluster events => 1 cluster per sensor for Reference Tell1 ( ≡ low irradiated sensor) • All cluster events for highly irradiated Tell1 • Beam @ top –Sec 3– Tell1 8 High Irradiation • Beam @ bottom –Sec 0– Tell1 5 High Irradiation • Test Module –beam @ Sec 0– R Sensor only Alessandra Borgia, SU Velo Meeting

  3. 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 Alessandra Borgia, SU Velo Meeting

  4. Beam @ Top: 300 V 400 V 500 V Tell1 8 1 Strip Clusters Only Beam intensity ~ 200k/spill for 300 V ~ 100k/spill for 400 & 500 V Alessandra Borgia, SU Velo Meeting

  5. Beam @ Top: 300 V 500 V 400 V Tell1 8 1 Strip Clusters on 5 2 Strip Clusters on 8 Beam intensity ~ 200k/spill for 300 V ~ 100k/spill for 400 & 500 V Alessandra Borgia, SU Velo Meeting
