Abstract

It is proposed a novel design of an X-ray monochromator which uses three crystals. The exit beam turns in horizontal plane on the angle 2α with respect to the incoming beam. So, this kind of monochromator is suitable for side beam-lines; several tunable beam-lines can be built for a one fan beam of synchrotron radiation (from wiggler or bending magnet). In contrast to the double-crystal scheme of general position considered previously (which also suitable for side beam-lines), the new variant does not lead to a tilt of exit beam profile.
