Abstract: | Kumakhov polycapillary optics is based on the effective passage of X-ray radiation through bundles of monocapillaries of various
configurations. The passage of radiation takes place because of the total external reflection of X-rays from the inner capillary
walls. In this work, the basic characteristics of intense quasi-parallel X-ray polycapillary microbeams from a laboratory
source with microfocus X-ray tube/polycapillary cylindrical structure are investigated theoretically (analytical consideration).
The data generated from theoretical estimations are compared with the experimental results. Several new generations of X-ray
analytical devices like, laboratory synchrotron, fluorescent spectrometers, reflectometers/refractometers, diffractometers,
X-ray microscopes and combinations of several such devices, are developed based on polycapillary optics. Besides, a number
of devices can be developed for the most modern research problems such as nanomateriology, namely, X-ray nanoscanner, portable
X-ray nanothickness indicator etc. X-ray tubes and the radiators, specially developed for polycapillary optics as efficiently
as possible, are used in all the devices mentioned above. |
