                                   ABSTRACT

     
  Radiation damage observed in the SVX and SVX' silicon vertex detectors in
  the CDF experiment at the Tevatron Collider at Fermilab provides an
  experimental measurement of the bulk radiation damage in silicon sensors  
  versus sensor radius from the beam and delivered luminosity.  These data are  
  related to the effective particle fluences, for example in equivalent 1 MeV  
  neutrons/cm^2, versus radius and luminosity.  These results are used to make  
  a best estimate of the bulk damage in the SVX~II during Tevatron Run II.
