“…However, on the contrary to channeling radiation in crystals when the electron is considered to be free along the channel direction (the continuous crystal potentials are transverse coordinate dependent), in our case, the electron is accelerated down the channel and known in literature as betatron radiation at laser wakefield acceleration 3 [27,92,93]. The latter results in shifting the projectile's frequency for transverse oscillations during the electron channeling in a plasma-ion channel, and thus, the radiation spectrum becomes changed [94].…”

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.

“…A self-injection experiment was performed at the SPARC-LAB test facility (INFN-LNF) by using the laser FLAME [19][20][21][22]. The main pulse characteristics were ∼1 J energy, delivered in 30 fs (FWHM) over a 10 μm diameter focus, corresponding to a laser strength parameter [4] a 0 ∼ 4.4.…”

“…The reconstruction of the electron trace space is then performed, which allows a complete measurement of the transverse emittance, including the correlation term. The experiment was performed at the SPARC-LAB test facility [19] through the interaction of the ultrashort ultraintense Ti:Sa laser FLAME [19][20][21][22] with a He gas-jet target. We show that the single shot measurement of both the betatron spectrum and the electron energy spectrum is capable to provide all the information about the transverse trace space of the accelerated electrons.…”

A new methodology able to model and reconstruct the transverse trace space of low-emittance electron beams accelerated in the bubble regime of laser-plasma interaction is presented. The single-shot measurement of both the electron energy spectrum and the betatron radiation spectrum is shown to allow a complete measurement of the transverse emittance, including the correlation term. A novel technique to directly measure the betatron oscillation amplitude distribution is described and tested at the SPARC-LAB test facility through the interaction of the ultrashort ultraintense Ti:Sa laser FLAME with a He gas-jet target. Via the exposed technique the beam transverse profile is also retrieved. From the study of the electron transverse dynamics inside the plasma bubble, the nonlinear correlation between the betatron amplitude and the divergence, i.e. the angle with respect the acceleration axis, is found. The angular distribution of the electron beam inside the bubble is retrieved. The knowledge of the trace-space density allows a more accurate measurement of the transverse emittance with respect to previous paradigms
