Go back MCNP simulations
A cylindrical target of heavy water approximately the size of a standard water bottle was subject to bremsstrahlung photons with an end point energy of 10.5 MeV. Ideal detectors with a width of 6" and height of 30" were placed 150 cm from the target at angles ranging from 0 to 180 degrees (relative to the beam axis). Here is a top down view of the simulation geometry:
