The effect of He and swift heavy ions on nanocrystalline zirconium nitride
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2014)
Recent studies have shown that swift heavy ion irradiation may significantly modulate hydrogen and helium behaviour in some materials. This phenomenon is of considerable practical interest for ceramics in general and also ...
Energy loss distributions of relativistic protons axially channeled in a bent silicon crystal
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2013)
A detailed study of the energy loss distributions of the relativistic protons axially channeled in the bent LT 100 GT Si crystals is presented in this work. The bending angle was varied from 0 to 20 mu rad, while the crystal ...
Energy loss distributions of 7 TeV protons channeled in a bent silicon crystals
(Nuclear technology and radiation protection, 2013)
The energy loss distributions of relativistic protons axially channeled through the bent LT 100 GT Si crystals, with the constant curvature radius, R = 50 m, are studied here. The proton energy is 7 TeV and the thickness ...
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 ...
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 ...
Quantum primary rainbows in transmission of positrons through very short carbon nanotubes
(Elsevier, 2016)
This paper is devoted to a quantum mechanical consideration of the transmission of positrons of a kinetic energy of 1 MeV through very short (11, 9) single-wall chiral carbon nanotubes. The nanotube lengths are between 50 ...
Effective quantum dynamics in a weakly anharmonic interaction in the vicinity of a focusing point
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2017)
We describe here the dynamic behaviors of a quantum ensemble of particles in a one-dimensional anharmonic potential well and of the corresponding classical ensemble in the vicinity of a focusing point. The anharmonicity ...
Superfocusing of channeled protons and subatomic measurement resolution
(Physical Review A, 2012)
In this work we analyze the superfocusing of protons channeled in a LT 100 GT Si thin crystal using the theory of crystal rainbows. The initial proton energy is 68 MeV and the proton beam incident angle is increased gradually ...
Rainbow channeling of protons in very short carbon nanotubes with aligned Stone-Wales defects
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2016)
In this paper proton channeling through armchair single-walled-carbon-nanotubes (SWCNTs) with aligned Stone-Wales defects has been investigated. The energy of the proton beam was 1 GeV, while the lengths of the SWCNTs have ...
Proton-silicon interaction potential extracted from high-resolution measurements of crystal rainbows
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2015)
This study provides a way to produce very accurate ion atom interaction potentials. We present the high-resolution measurements of angular distributions of protons of energies between 2.0 and 0.7 MeV channeled in a 55 nm ...
