Comparison of simulated mean energy losses ΔE per distance and mean differential energy losses dE/dx (both in [MeV/mm]) of muons in various target materials. The top figure shows simulated mean energy losses (symbols) and compares them to tabulated reference values (solid lines). The red curve (boxes) shows the results for uranium dioxide, theorange curve (circles) corresponds to polyethylene, the blue curve (pentagons) corresponds to stainless steel, the green curve (up-pointing triangles) corresponds to ductile iron and the violet curve (down-pointing triangles) corresponds to zirconium alloy. The lower five figures show for each material the relative deviations between simulated energy loss per mm and tabulated mean stopping power values.
