Figure 1
(a) Running motorcycle frame mounted on the high-capacity sample-positioning table of the rig inside EH2, I12, DLS. (b) Beam attenuation through the engine cross section. The position of the cross section A–A is demonstrated at the top of the figure. The cast Al attenuation is shown in red, the steel-piston skirt attenuation in blue, the cast iron con-rod in cyan and air attenuation in grey. The absorption coefficient μ for each metal is taken from NIST for energy 150 keV and the attenuation is according to the Beer–Lambert law. |
