Description
The need for ultra-radiation hard semiconductor detectors for the tracker
regions in high energy physics experiments at a future high luminosity
hadron collider like the LHC Upgrade has led to the formation of the CERN
RD50 collaboration. The R&D directions of RD50 follow two paths:
understanding radiation effects, and finding mitigation through the use of
new materials, device engineering and optimized operations, all of which will
be covered in this paper. We will compare recent data on charge collection in
new materials with electrical characterization, and show the effects of
trapping, loss of full depletion and leakage current as a function of
accumulated fluence of hadrons. An emerging picture of how a future
tracking detector might look like will be presented.
