We can divide the energy loss problem into two parts: energy loss for incoming electrons (before the primary scattering interaction), and energy loss for outgoing electrons (after the primary scattering interaction). The tables below, with reference to Chiranjib's dissertation, show the materials in the path of each set of electrons, plus a mean energy loss calculation for a nominal scattering angle of <math>45^{\circ}</math>.
Please note that the actual energy loss curve follows a Landau distribution, and the most likely energy loss value is NOT the same as the mean energy loss reported below.
Chiranjib Dutta's dissertation (especially the appendices) is a good resource.
Mean Energy Loss for Incoming Electrons
| Material | <math>X_0</math> (cm) | Thickness (cm) | Thickness (<math>X_0</math>) | Mean Energy Loss <math>E_f - E_i</math> |
| Beam pipe window (Be) | 35.28 | 0.0254 | 0.000719 | 0.00072 |
