Comparing radiation tolerant materials and devices for ultra rad-hard tracking detectors

The need for ultra-radiation hard semiconductor detectors for the inner tracker regions in high energy physics experiments of the future generation can be satisfied either with materials which are inherently more radiation hard than float zone silicon or with special detector structures with improved radiation resistance. This report compares directly the data on the performance of rad-hard materials and devices proposed for the superLHC.
