Advanced Channeling Technologies in Plasma and Laser Fields

Abstract

Abstract. Channeling is the phenomenon well known in the world mostly related to the motion of the beams of charged particles in aligned crystals. However, recent studies have shown the feasibility of channeling phenomenology application for description of other various mechanisms of interaction of charged as well as neutral particle beams in solids, plasmas and electromagnetic fields covering the research fields from crystal based undulators, collimators and accelerators to capillary based X-ray and neutron optical elements. This brief review is devoted to the status of channeling-based researches at different centers within international and national collaborations. Present and future possible developments in channeling tools applied to electron interactions in strong plasma and laser fields will be analyzed.

Advanced channeling technologies for X-ray applications

“…As shown in this report, generally saying, channeling phenomenology might be applied for any kind of charged or neutral particle beams motion in the external fields defined by long transversely limited channels (Dabagov, 2018). Moreover, various features of the structure as a periodic structure, for instance, may supply additional peculiarities of beam passing through such structures.…”

X-ray applications and recent advances @ XLab Frascati

“…In addition, the presence of a facility dedicated to X-ray imaging and tomography, coupled with the opportunity to use polycapillary optics (lens and semilens systems) enable users to perform 2D/3D reconstruction of a sample through the complementary analysis of their composition and even in the case of materials with a very low concentration of their components. The versatility of these powerful techniques allows their application throughout several different interdisciplinary sectors such as cultural heritage, biology, geology and industry with performances overcoming the limits presented by some techniques currently adopted in research laboratories (Dabagov and Gladkikh 2019;Dabagov 2018). This is possible thanks to the use of the polycapillary optics that enables to create a very bright X-ray source from a conventional one and then obtain a powerful quasi-parallel or a focused beam from a divergent source, according to a characteristic "semi-barrel" or "barrel" shape, respectively, and to the purpose of the analysis to perform.…”

“…Thus, the channeling formalism can be applied to describe the motion of particles in various media, for instance, in laser and plasma channels (see [18][19][20][21][22] and Refs. in the review paper [23]), as well as the propagation of radiations in self-organised subsystems [24][25][26][27].…”
