The requirements at the Large Hadron Collider (LHC) at CERN have pushed the present day silicon
tracking detectors to the very edge of the current technology. Future very high luminosity colliders or
a possible upgrade scenario of the LHC to a luminosity of 10**35 cm**-2 s-1 will require semiconductor
detectors with substantially improved properties. Considering the expected total fluences of fast
hadrons above 10**16 cm-2 and a possible reduced bunch-crossing interval, the detector must
be ultra radiation hard, provide a fast and efficient charge collection and be as thin as possible.
The objective of the CERN RD50 Collaboration is the development of radiation hard
semiconductor detectors for very high luminosity colliders, particularly to face the requirements introduced above.
The research activity of RD50 has been organised in two major lines, Material Engineering and
Device Engineering.
