Figure 2
Calculated PSD of images of Xe + ion beam eroded fused silica surfaces for fluences. From Φ = 2.25 × 1017 cm-2 up to Φ = 1.35 × 1019 cm-2, Eion = 600 eV, jion = 300 μ A/cm2, ion incidence angle of α = 65°. The dotted vertical lines mark the shortest and longest ripple wavelength, respectively. The arrows highlight the wavelength at the corresponding fluence.
