  1. Charge Collection in CVD Diamond Paris – Nov. 22, 2012 R. Kass 35

  2. Radiation Damage - Basics • Charge trapping the only relevant radiation damage effect • NIEL scaling questionable a priori • Egapin diamond 5 times larger than in Si • Many processes freeze out • Typical emission times order of months • Like Si at 300/5 = 60 K – Boltzmann factor • A rich source of effects and (experimental) surprises ! Paris – Nov. 22, 2012 R. Kass 40

  3. Summary of RD42 Test Beam Results for CVD Diamond k is relative damage constant Paris – Nov. 22, 2012 R. Kass 41
