Figure 4
Illustration of the beam-tilter rotation during reflectivity measurements. The position of the beam-tilter rotation (mchi) is shown at (a) mchi = 0, α = β = 0°, (b) mchi at 45°, α = β = 4.1° and (c) at 90°, α = β = 5.8° at the maximum position of the angles α and β. The detector height, vertical and horizontal translation and rotations follow the reflected beam. |
