(a) Photograph of the sample alignment on the scintillation screen, with ROI for sample positions marked by dashed lines. Energy-window integrated transmission images captured around the neutron absorption resonance energies for (b) gold (Au-197) at 4.9 eV, (c) tantalum (Ta-181) at 4.28 eV, and (d) iridium (Ir-191) at 0.54 eV.
