Abstract :
We developed an apparatus for multiple energy X-ray holography (MEXH) at third generation synchrotron facility, SPring-8. The combination system of a cylindrical lithium fluoride crystal and an avalanche photo diode in our apparatus enabled high countrate detection of the fluorescence from samples. From the measurements repeated 10 times, reproducible holographic undulations were obtained from the strontium titanate single crystal, although 10% intensity change of the incident beam occurred. This result revealed that the holographic data provided by our MEXH apparatus was highly stable to the variation of the incident beam intensity.
