Figure 7
(a) First order flux as a function of energy and cff. (b) First order flux normalized to per energy. (c) The FoM function. (d) Data after being normalized at each energy, in the same way as in (b). Note the discontinuity at 1100 eV due to the second order Pt and Au M-edge absorption; the same absorption occurs at ∼2200 eV for the first order. The semi-transparent line in (d) shows a fit through the maxima to offer an accessible `rule-of-thumb'. |
