    Thickness of material to absorb electron beam

    Homework Statement Beam of electrons (charged particles!) is directed to copper absorber with known energy (E= 10MeV) and intensity (10^8(s*cm^2)^-1) . I need to find the thickness of absorber so that all electrons would be absorbed. Also under what conditions does it happen and what is...

    What Interactions Remove Energy from a Photon Beam in an Iron Absorber?

    Homework Statement I have this task: A collimated monochromatic beam of photons with intensity 10^20/s and energy 10 MeV is directed to a iron absorber with thickness 3 cm. What kind of interactions are expected? Suppose, each interaction removes one particle from the beam. I need to know...
