(a) Photograph of the experiment set-up for the reflectivity measurement taken in the hutch of R&D NSLS-II beamline at NSLS (X16A). (i) Ionization chamber, (ii) L-shaped mirror, (iii) x/y slits, (iv) PIN diode detector. (b) Reflectivity curve taken from both surfaces simultaneously. The inset shows details of the reflectivity curve showing convoluted Pendellösung effects from both surfaces. |
