(a) Ion yields for several Ar charge states at 6.5 keV as a function of fluence before the volume integration, equation (1). Note that we employ logarithmic scales for both axes. (b) The same ion yields but after the volume integration using the calibrated parameters in equation (25). The vertical arrow indicates FG = 3.85 × 1012 photons µm−2, which is the calibrated global peak fluence. The dashed lines representing the slope of unity are marked at the vertical arrow to guide the eye. |
