Figure 4
The reflected X-ray beam imaged by the CCD detector from an orthoclase (001)–water interface at a specular reflection condition at L = 1.9 (r.l.u.), with the logarithmic color scale shown on the right. The solid white line indicates the region that includes the scattering signal, and the dashed white line indicates the defining slit aperture and the corresponding area of the CCD that detects the background signal. Outside of the dashed line, the CCD signal corresponds only to a CCD read signal and any dark counts. |
