Figure 5
Nitrogen emission spectra of ammonium nitrate (blue) and RDX (red) obtained with the TES array. Fine structure due to local chemical environment is clearly visible and distinct between the two compounds (see text for identification of the numbered features). The different chemical structures are recognizable in the molecular cartoons on the right. The 2.5 eV instrumental response function is shown on the left. The inset shows the same emission spectra with an expanded energy range; the reflected beam and the main emission lines are marked. The spectra of ammonium nitrate and RDX were collected in 29 and 23 min, respectively, with 2 × 1010 photons s−1 input from a bending-magnet beamline using a 45 pixel TES detectors with pixel size 320 × 305 µm. |
