NaI: the specular reflected beam position on the detector (left) and specular reflected intensity (right) at qz = 0.3 Å−1 for a 0.5 M NaI solution at different laser/X-ray overlap positions, maxima (a, b), middle turning points (c, d) and minima (e, f), along the trajectory shown in Fig. 7(b). (g, h) Corresponding data for water. A 258 nm laser beam with a diameter of 15.3 mm and a fluence of 5.4 µJ cm−2 was used. The laser was switched on at t = 0 s (green line) and switched off at t = 10 s (red line). Measurements are averaged over 1 s. |
