Description
Channeling is a well known phenomenon mostly related to specific motion of charged particles in aligned crystals. Since the middle of 60s of the last century when its phenomenology was developed, channeling of high-energy leptons (electrons/positrons of several MeV up to hundred GeV energies) and hadrons (protons/ions of tens GeV up to several TeV energies) has been applied to shape the charged beams as well as to produce high power X-ray and gamma radiation sources at various famous world research centers. Further studies have shown the feasibility of channeling phenomenology application for description of other various mechanisms of interaction of charged and neutral particles beams in solids, plasmas and electromagnetic fields covering the research fields from crystal/laser/plasma based undulators and collimators to capillary based X-ray and neutron optical elements.
Channeling studies are resulted in developing a new X-ray technique presently known as polycapillary optics, very compact solution to effective handle X-ray beams of wide frequency spectrum that provides an essential advantage in designing innovative scientific and industrial instruments in optics, spectrometry and imaging.
Within this review talk I will discuss actual X-ray channeling-based projects paying main attention to the basics of polycapillary optical systems as well as its use for advanced tomographic studies.
