FIELD: physics.
SUBSTANCE: invention concerns resorts for formation of a directed bundle of a X-rays from a divergent bundle created by the point or quasi-point source. The device for formation of a directed bundle of X-rays contains a catopter in the form of a surface of gyration and has a focal point. The focal point is located on an axial line of the specified surface of gyration. Forming surfaces has the curve shape. The tangent to the specified curve in any point of this curve forms with a direction on a focal point the same angle. This angle does not exceed a critical angle of the full exterior reflexion for X-rays of the used range. The catopter is or an interior surface of the shaped tubular device or a surface of the shaped channel in a monolithic body, or boundary between the surface of the shaped monolithic core and a stratum of the coat superimposed on this core. The specified tubular device or the channel is executed from a material reflecting X-rays or has a coat from such material. The specified core is executed from a radiotransparent material. The specified coat of the core is executed from a material reflecting X-rays.
EFFECT: increase of radiation source angle capture.
