Apparatus for X-ray analysis and apparatus for supplying X-rays |
摘要 |
Apparatus for X-ray analysis has a combination of a rotating target X-ray tube and a composite monochromator. The composite monochromator has a first and a second elliptic monochromators joined with each other side by side. Each of the elliptic monochromators has a first focal point at which an X-ray focal spot on a target of the X-ray tube is disposed. Each of the elliptic monochromators has a synthetic multilayered thin film whose d-spacing varies continuously along an elliptic-arc. The shortest distance between the X-ray focal spot and the composite monochromator is set to 40 to 100 mm. Under the shortest distance condition, the effective focal spot size on the target is set to 40 to 100 micrometers to obtain the maximum X-ray intensity on a sample to be analyzed.
