Description

Interaction of different kinds of radiation in solids has been studied
since scientific community started to operate with penetrating
radiations.
Among various research branches coherent phenomena of
radiation propagation into solids, as coherent bremsstrahlung,
channeling and related effects in crystals, attract attention because
it can create a strong flux of photons in broad energy intervals,
starting from optical frequencies, via soft and hard X-ray, up to
(-frequencies.
The latter makes this research field more and more
attractive due to the importance of creating new powerful photon
sources like the next generations of synchrotrons, free-electron
lasers, Z-pinch machines, etc.
Another approach to the problem of
searching for intense radiation soources is to increase the radiation
density of existing X-ray and (-sources that can be solved by means of
novel optical elements, for instance, capillary optics. Passage of
charged particles through periodic systems and propagation of neutral
particles (photons, neutrons) in capillary systems of micron and
submicron channel sizes, even strongly different by nature, have much
in common as both can be described within the united channeling
theory.
Moreover, the use of this analogy can much simplify the
researches in both areas.
