Figure 2
(a) Schematic illustration of the experimental geometry using the multi-functional chamber mounted on the heavy-load two-circle diffractometer at the FXS endstation. The blue and red arrows indicate incident X-ray and laser beams, respectively, while the orange arrows represent the motions of θ and 2θ rotational stages. (b) Side view of the chamber connected to a vacuum pipe from the XSS beamline. The X-ray beam (blue arrow) enters the chamber through the vacuum pipe, and the laser beam (red arrow) is delivered through a 25.4 mm-diameter quartz window. (c, d) Top views of the chamber configurations: (c) without θ-rotation and (d) with θ-rotation of the diffractometer. The green arrows indicate diffracted/scattered X-ray beams exiting through the 203.2 mm-diameter chamber windows, while the purple arrow denotes the beam blocked by the chamber or ports. (e, f) Top view (e) and side view (f) of the experimental setup in a transmission WAXS geometry. (g) Schematic of a cylindrical pole sealing the 56 mm-diameter circular opening located at the bottom of the chamber, secured with O-rings and supported by ball bearings for vacuum integrity. (h) Photograph of the cylindrical pole assembly. (i) A 140 µm-thick Kapton film window installed on the chamber. (j) Example of a punctured 50 µm-thick Kapton film due to air pressure during the chamber pumping process. (k, l) Quartz optical window used for laser beam incidence. The optical laser beam [red arrow in (k)] passes through the unobstructed portion of the opening, avoiding the flange's inner edge (l). |
