Abstract
The results of an accelerated life time test of neutron irradiated ABB Hafo radiation hard LEDs are presented. After a 1 MeV neutron irradia tion with up to 1.4 x 10(14) n/cm(2) at the Rutherford Appleton Lab (R AL) ISIS facility, the LEDs have been operated without seeing any degr adation due to ageing for a time which is estimated to correspond to a bout 57 years of operation in the ATLAS SemiConductor Tracker (SCT) at the Large Hadron Collider (LHC). The irradiation decreased the light output of the LEDs substantially, but during the operation of the LEDs a fast annealing of most of the irradiation damage was observed.
