A method for the magnification of xhyphen;ray radiographic images is described and demonstrated. This magnifier employs two successive asymmetric diffractions of an xhyphen;ray beam from highly perfect silicon crystals. The two diffractions magnify the beam in two perpendicular directions. A device with a magnification of 25times; is demonstrated for CuKagr;radiation. This device preserves and sometimes improves the resolution inherent in the radiographic technique. The xhyphen;ray magnifier is particularly useful in circumventing the relatively poor spatial resolution of electrohyphen;optical imaging systems needed for realhyphen;time observations. Basic limits on magnification and resolution using this method are described.
