(a) Fitted experimental EUV reflectance curves across the wavelength of the radiation impinging at 1.5° from normal, based on the binary model. The green curve shows the maximum possible reflectance in the water window assuming a perfect multilayer system without roughness or interdiffusion. (b) The optimal model based on the analysis of the EUV reflectance (cf. Fig. 2a) shows a clear mismatch with the measured XRR curve in the second Bragg peak. |
