MCNP6 was used to simulate a pencil point electron beam incident on a 1 cm thick Al bremsstrahlung radiator. A  to-scale diagram of the geometry and materials used in the simulation is shown below. The geometry was designed to model closely after the IAC Main Hall area.

Shown below are linear and log plots of the energy distribution of the bremsstrahlung photons that reach the experimental room. Plot titles are the energy of the incident electrons. 750,000 beam electrons were simulated for each incident electron energy.
