TF Simul PhotField IAC 2n
The goal of this simulation is to determine the photon field in the shielded cell that result from 10.5 MeV electrons hitting 2 cm thick Aluminum radiator.
Electrons impinge a 3 x 10 x 3 cm aluminum radiator. The 10.5 MeV electrons radiate in the air and the aluminum before stopping in the aluminum.
Photons are emitted in all directions. A 6 foot high wall made of 36" thick concrete is located downstream of the Aluminum radiator.
A 30 cm radius lead collimator is position within the wall.
