COG is a Monte Carlo computer code designed to solve the Boltzmann equation for transporting neutrons and photons and, in future versions, charged particles. The techniques included in the code make it most suited for solving deep penetration (shielding) problems, but provision is also included for solving criticality problems. The current versions of COG run on Cray-1 and Cray/X-MP computers. We expect that future versions of the code will function on other machines but will still require substantially the same inputs described in this manual.
