Paper Abstract

An experimental set-up for the observation of intensity fringes of x-rays propagating in vacuum between two separated crystals is reported. In this experiment a Bragg reflection near 90 degrees was used to observe the oscillations of the measured intensity between the monochromator and mirror crystals. The x-ray intensity profiles; were collected as a function of the angular position of the crystal-mirror in the vicinity of a Si(800) reflection at a synchrotron radiation energy of about 9.1344 keV. Interference contrast in the experimentally observed intensity profiles proves the phase-sensitive nature of the intensity fringes. Novel approach to interpretation of synchrotron radiation coherence is discussed. The experimental observations open new possibilities for novel applications in high-energy radiation optics.
