The Cygnus Dual Beam Radiographic Facility consists of two identical radiographic sources, Cygnus 1 and Cygnus 2, each with the following specifications: 4-Rad dose at 1 m, 1-mm spot size, 50-ns pulse length, and 2.25-MeV endpoint energy. Cygnus 1 and 2 have been used for radiography of subcritical experiments at the Nevada National Security Site (NNSS) since 2004. The Cygnus Facility is located in an underground tunnel complex named U1a. The Cygnus sources were developed as a primary diagnostic for these experiments. The first subcritical experiment to utilize Cygnus, Armando, was executed on May 25, 2004. Since Armando, several other subcritical experiments have been executed in front of Cygnus, as well as physics experiments and plutonium calibration tests.
