Crystal Photography with Divergent X-Rays

X-ray imaging with parametric X-rays (PXR) from a lithium fluoride (LiF) crystal

X-ray imaging produced by parametric X-rays (PXR) is reported. The PXR are generated using an electron beam with energy of 56MeV and currents up to 6.4 mA, that interacted with a 1.5-mm thick lithium fluoride (LiF) crystal target in Laue geometry. The LiF (2 2 0) crystallographic plane was used with a Bragg angle (yB) near 151 to produce PXR with energy 16.6 keV and FWHM of 3%. This intense, di...

Berry-phase translation of x rays by a deformed crystal.

We experimentally demonstrated an enhanced translation of an x-ray beam nearly parallel to the diffracting planes over millimeter distances in a deformed silicon crystal. This effect is a consequence of the Berry-phase effect in phase space [K. Sawada, Phys. Rev. Lett. 96, 154802 (2006)], which enables an interplay between the gap in the dispersion surface in momentum space and the atomic displ...
