Introduction
Promising new physical results are related to some very rarely produced particles
- high event rate (109/sec at LHC), very good spatial resolution and fast signal read out required, can be fulfilled with silicon detectors, however:
Detectors and electronics will be harshly irradiated!
- ATLAS - Inner Detector: Feq up 3x1014 cm-2 per year (1 Billion Lung x-rays)
- 10 years of operation have to be guaranteed
- What is the impact on silicon ?
- How can it be made harder ?
