The High Flux Neutron Radiography Facility (HFNRF) has been fabricated, tested and used successfully. This paper describes the final design features and presents the results of the radiation measurements made during the characterization tests. A complete neutron spectrum (from 10{sup {minus}8} to 15 MeV) has been measured with the aid of activation foils. Gold foils were used to determine a thermal neutron flux of 9.4 {times} 10{sup 7} n{center dot}cm{sup {minus}2}s{sup {minus}1} at the image plane in the Sandia Annular Core Research Reactor (ACRR) operating at 1.0 MW. The reactor can be operated at 20 MW for 10-second periods with the radiography tube in the central cavity. In pulse mode with peak power of 24,000 MW and a 7.6 ms FWHM {approximately}1.9 {times} 10{sup 10} n{center dot}cm{sup {minus}2} will be generated with a peak flux of 2.3 {times} 10{sup 12} n{center dot}cm{sup {minus}2}s{sup {minus}1}.
