Position of the simulated 1 cm slices assuming constant, room-temperature mass density (continuous line) and interpolating the mass density obtained with the simulation (dashed line). The grey areas have equal size, therefore providing the same X-ray absorption before the second simulated point. The simulation parameters were 200 mbar of argon gas, 18 mm of attenuator radius and X-ray spectrum corresponding to a U18 undulator with 2 mm × 2 mm beam size. |
