Brem Spectrum

Below is the photon energy distribution (from Brem & pair production) using a 2mm Pb target for two different incident electron energies; 6 and 10 MeV. The photons are 1 cm downstream of the target and intersection a large forward region.

Now move the scoring region downstream to a position representing the location of a NaI detector.
