The RD20 collaboration is undertaking systematic studies of the radiation hardness of prototype detectors in order to construct silicon microstrip tracking detectors at the LHC. Results from irradiations on pside and n-side strips, both fabricated on n-type silicon are presented.
ResultsThe principal conclusions from the work to date are summarised below [ 1,2,7,12,131.Leakage currents have been measured with neutrons, protans and gammas and are known to be proportional to par&le fluence, with volume current density = damage consraq x fluence. The neutron damage constant is well established fmm our own work and others [7-111 to be -7~1 0 -l~ A.cm-l for
