Schematic of the key elements of a three-dimensional polychromatic X-ray microprobe. The intense white-beam source can either be passed directly to the focusing mirrors or monochromated by a special translating monochromator. The KB mirrors focus the polychromatic radiation to a submicrometer spot. The sample is translated with a precision three-axis stage, and a heavy-Z wire runs near the sample surface to decode the origin of the Laue patterns along the incident X-ray beam. The X-ray Laue patterns are detected with an X-ray-sensitive CCD. |
