[Gate-users] photon flux crossing a surface

[Alex Vergara Gil]

Dear Simon

Yes, I know Fluence Actor but what I want is to register ONLY photons,
I have to determine the optimal thickness for a material to produce
bremsstralung photons, so I have to remove electrons from fluence,
being electrons what my source produces in the first place.

Regards
Alex
