Thickness of material to absorb electron beam

  1. Jan 25, 2012 #1
    1. The problem statement, all variables and given/known data
    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 absorbed dose then?

    2. Relevant equations

    D=(1.602*10^-10)* (fluence*E/mass thickness) (Gy)

    3. The attempt at a solution

    so to get absorber thickness should I mass stopping power multiply by copper density and then divide it from the beam energy?
    is it thick foil condition?
