The Simulation

Photons with a Bremsstrahlung energy distribution are incident upon 64 4 mm dia. thorium cylinders with 1 cm center to center spacing (see the neutron flux plot below). Photofission neutrons were simulated using the MCNPX ACE model. Upon the creation of a neutron, its initial direction of travel is logged and compared with its direction of travel when it leaves the simulation area. The target configuration pictured below is surrounded by a r=100cm cylinder (axis going into the page) of air.
