[Gate-users] Record only photon interactions

[Cheng Xu]

Dear all,

Does anyone know how to simulate only the photon interactions and discard the electron interactions and electron scattering in GATE, because I want to study the photon interactions first and then do the charge sharing simulation analytically. However, with the electron interactions and scattering included, when the photon interaction position is close the boundary between two pixels, part of the energy is shared by the neighboring pixel as a result of electron scattering which I do not want. When I disable the electron scattering and ionization in physics list, no energy is recorded. So is there a way to simulate only photon interactions and record the complete energies, seems <adder Compton> command discards part of the deposited energy when the electron track travels to the neighboring pixel.

Thanks in advance!
