Kirkpatrick–Baez microprobe on the basis of two linear single crystal Bragg–Fresnel lenses

Abstract

X-ray microprobe on the basis of two linear single crystal phase Bragg–Fresnel lenses in Kirkpatrick–Baez geometry has been suggested and realized for hard x rays. The Kirkpatrick–Baez optics has been tested by two-dimensional imaging the x-ray source spot of a conventional sealed-off x-ray tube with Cu target (λ=1.54 Å). The possibility of applying this kind of microprobe at a synchrotron radiation source is discussed.
