TB Analysis

Alessandra Borgia & Marina Artuso

VELO Group Meeting,

Friday

April 3, 2009

important data info
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
