Figure 6
Terbium-doped glass fiber for aligning the sample spindle with the X-ray microbeam. X-ray-sensitive scintillating glass is easily drawn into fibers of diameter 30 µm or smaller. A cross-hair is also shown in the figure with tick marks every 10 µm. The broad green glow has a 40 µm base corresponding to the exit diameter of the capillary tip, and the focused radiation is visible as a bright spot at the center. |
