Rainbows with a LT〈1 1 1〉GT Si thin crystal
(European Physical Journal B. Condensed Matter and Complex Systems, 2000)
This study is devoted to the transmission of Ne10+ ions through a (111) Si thin crystal. The ion energy in 60 MeV and the crystal thickness is varied from 159 to 478 atomic layers, i.e., within the first rainbow cycle. The ...
Influence of the dynamical image potential on the rainbows in ion channeling through short carbon nanotubes
(Physical Review A, 2006)
We investigate the influence of the dynamic polarization of the carbon valence electrons on the angular distributions of protons channeled through short (11,9) single-wall carbon nanotubes at speeds of 3 and 5 a.u. ...
Proton channeling through long chiral carbon nanotubes: The rainbow route to equilibration
(Physics Letters A, 2008)
In this work we investigate the rainbows appearing in channeling of 1 GeV protons through the long (11, 9) single-wall carbon nanotubes. The nanotube length is varied from 10 to 500 pm. The angular distributions of channeled ...
Focusing Properties of a Square Electrostatic Rainbow Lens Doublet
(Nuclear technology and radiation protection, 2015)
This is a study on the properties of a square electrostatic rainbow lens doublet. The said optical element consists of two square electrostatic rainbow lenses with the second lens axially rotated for 45 degrees with respect ...
Angular distributions of high energy protons channeled in long (10,10) single-wall carbon nanotubes
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2009)
In this work we study the angular distributions of 1 GeV protons channeled in long (10,10) single-wall carbon nanotubes. The nanotube length, L, is varied between 10 and 100 mu m. The angular distributions of channeled ...
Radiobiological Outcomes, Microdosimetric Evaluations and Monte Carlo Predictions in Eye Proton Therapy
(Applied Sciences, 2021)
CATANA (Centro di AdroTerapia ed Applicazioni Nucleari Avanzate) was the first Italian protontherapy facility dedicated to the treatment of ocular neoplastic pathologies. It is in operation at the LNS Laboratories of the ...
Designing of technological scheme for conversion of Cr-rich electroplating sludge into the black ceramic pigments of consistent composition, following the principles of circular economy
(Journal of Environmental Chemical Engineering, 2021)
Development of method for the complete conversion of Cr-containing electroplating sludge (ES) into the black inorganic pigment was presented. Difficulties related to the ES complex, variable composition and inhomogeneity, ...
Study of graphene by proton rainbow scattering
(European Physical Journal D. Atoms, Molecules, Clusters and Optical Physics, 2023)
We have studied the transmission of 5 keV protons through graphene. Proton dynamics was modeled by classical theory. Proton trajectories define a mapping of the set of initial proton positions to the set of scattering ...
Nonlinear dynamics of positron resonances in a carbon nanotube
(Chaos, Solitons and Fractals, 2023)
We have investigated long-time dynamics of the transverse resonant states occurring in positron transmission through a chiral single-wall carbon nanotube in the channeling mode. This was done by a detailed analysis of ...
Deflection of a 100-MeV positron beam by repeated reflections in thin crystals
(JETP Letters / Journal of Theoretical and Experimental Physics, 2014)
The phenomenon of the deflection of a charged particle beam due to channeling in a bent crystal is thoroughly investigated and successfully applied for the extraction of the beam in high-energy accelerators, at the energies ...
