Definitions
- a device for generating short-wave electromagnetic radiation in particular in the X-ray and gamma radiation range, by interaction between accelerated charge carriers, in particular electrons or positrons, and a crystal lattice, with a charge carrier source for generating a bundle of high-energy charge carriers and with a crystal arrangement such as this arranged in the way of the charge carrier beam bundle that the charge carriers pass through the crystal lattice of the crystal arrangement parallel to a predetermined lattice direction (lattice plane, lattice axis) ("channeling condition”), which is characterized in that the crystal arrangement of the charge carriers in at least a plane passing through the axis of the carrier beam beam is traversed with directions which essentially converge at a predetermined point, and that the crystal arrangement is in an arc around the predetermined point is arranged so that the channeling condition is essentially fulfilled for all charge carrier beam paths.
- a predetermined lattice direction lattice direction
- the charge carrier source supplies a charge carrier, in particular electron beam 212, convergent in the plane of the drawing and essentially parallel in the plane perpendicular thereto.
- the electron beam source can contain, for example, a cylinder electron lens.
- a platelet-shaped single crystal 214 Arranged in the path of the electron beam 212 is a platelet-shaped single crystal 214 which is cylindrically curved about an axis running perpendicular to the plane of the drawing (the curvature of the crystal is shown in an exaggerated manner in FIG. 1 and in FIGS. 3 and 4 for clarity).
