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
