This patent describes an x-ray source with dual monocrystal targets. It comprises: a first monocrystal having parallel lattice planes, and an optically flat, slant cut, planar face extending at an angle {theta}{sub {ital B}} relative to the lattice planes where {theta}{sub {ital B}} is the Bragg angle, first means located to excite the first monocrystal at the face, and along a line at the intersection with the face of another plane normal to the face and normal to the lattice planes, and other means producing beams of Kossel K{alpha}{sub 1} photons impinging on the line at the face, the beams directed at angles 2{theta}{sub {ital B}} relative to the line, whereby intense x-ray emission occurs, in a direction which is an extension of the line, the other means comprising a second monocrystal having a face at an angle {theta}{sub {ital B}} relative to the line, and electron gun means directing second beams of electrons at the face of the second monocrystal.
