Figure 1
Side view (cross section) of the measurement setup. The white X-ray beam is travelling from right to left (y-direction) and traverses a thin CVD diamond window that is held in a water-cooled copper support. A pinhole camera with a variable camera length L records the back-scattered X-rays. The pinhole is located at the tip of the conically shaped nosepiece at a distance D from the window. The pinhole camera is placed at an angle of 36 (±2)° with the beam path, which is unobstructed. The pinhole camera axis is in the YZ plane. The CVD diamond window and pinhole camera setup (dashed box) are placed in a vacuum chamber and can be translated in the Z-direction using a remote-controlled stepper motor.
