Figure 3
A top-view schematic showing the experimental setup for measuring the albedo F and scattering S(θ) in Section 2. The three beam-stop support frames are shown in green, with frame #1 in the beam (red). Six different samples are mounted on each frame. The tube detectors are shown in blue, with 10B-Al shielding in black. The 48-tube vSANS detector panels are labeled FL, FR, ML and MR, where the panel label names use L and R to represent the left and right panels, respectively, and F and M to represent the front and middle detector carriages, respectively. The eight-tube array used for the albedo measurements is shown facing the beam stops. The beam is offset 50 mm from the side of the eight-tube array. The three beam-stop frames are at distances L = 0.36 (as shown), 0.44 and 0.49 m from the eight-tube array. |
