Figure 6
(a) Total yield absorption spectra of nitrogen measured with monochromatic light from the 600 lines mm−1 grating (G 600) and the 1200 lines mm−1 grating (G 1200), at an exit slit setting of 50 µm. Solid lines are least-squares fits of Voigt functions as described in the text, dashed lines show the decomposed lowest-energy peak. The intensity ratio between the first valley and third peak (v/p) is indicated. (b) Calculated energy resolution of the beamline optics at the aperture settings of the nitrogen spectra. Experimental values from nitrogen XAS are marked. |
