(a) The optimal energy (right-hand axis) as a function of sample thickness for Al and Fe on ID31, assuming a flux independent of energy. The corresponding count rate for a 1 mm3 sampling gauge for (311)Al and (211)Fe expected for the optimal energy is also shown (left-hand axis). (b) The normalized distance (path length/attenuation length) based on the optimal energy as a function of depth. |
