ATLAS Internal Note No. 183, September 16, 1997 (approx. 11MB, compressed, with photographs)
One of the technologies proposed for the readout of the ATLAS SemiConductor Tracker (SCT) uses optical links based on Light Emitting Diodes (LEDs) or Vertical Cavity Surface Emitting Laser Diodes (VCSELs). Mounted near the detector modules close to the interaction point, these devices would be subject to fluences on the order of 1014 charged hadrons and 1014 neutrons per cm2, and to an ionizing dose of about 105 Gy during 10 years of operation at the Large Hadron Collider (LHC). Obviously, both the radiation hardness and the lifetime of LEDs and VCSELs must be studied carefully before they can be used in such an environment.
