Use of Kumakhov optics for x-ray analysis

Use of Kumakhov optics in the element analysis permits to increase sharply its sensitivity owing to the scattered radiation suppression. We used the capillary lenses in several schemes. The sensitivity of x-ray analysis is increased in all these schemes. On the basis of investigations, a new x-ray spectrometer with a capillary lens was created by the Institute for Roentgen Optics.
