Channeling star effect with bundles of carbon nanotubes
(Physics Letters A, 2006)
We report here about occurrence of the channeling star effect in the transmission of high energy protons through the bundles of (10. 10) single-wall carbon nanotubes, when the beam divergence is larger then the critical ...
Origin of ringlike angular distributions observed in rainbow channeling in ultrathin crystals
(Physical Review B: Condensed Matter and Materials Physics, 2012)
Using the theory of crystal rainbows, we prove that the well-known doughnut patterns observed in ion channeling in thin crystal membranes are manifestations of the rainbow effect. This is done by a detailed morphological ...
Rainbows with Crystals and Nanotubes
(Nanoscience and Nanotechnology Letters, 2012)
This review paper is devoted to the crystal rainbow effect, which occurs in ion channeling in crystals and nanotubes. We begin with a description of crystal rainbows. Then, we analyze the evolution of the angular distribution ...
On the dechanneling of protons in Si [110]
(European Physical Journal B. Condensed Matter and Complex Systems, 2003)
In the present work; the dechanneling of protons in Si [110] is studied combining theoretical Monte-Carlo and phenomenological simulation results in the energy range E-p = 1.8-2.4 MeV. The applicability of a Gompertz type ...
Simulating radial dose of ion tracks in liquid water simulated with Geant4-DNA: A comparative study
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2014)
An accurate modeling of radial energy deposition around ion tracks is a key requirement of radiation transport software used for simulations in radiobiology at the sub-cellular scale. The work presented in this paper is ...
Theory of rainbows in thin crystals: The explanation of ion channeling applied to Ne10+ ions transmitted through a LT 100 GT Si thin crystal
(Physical Review B: Condensed Matter and Materials Physics, 2000)
The theory of crystal rainbows is presented. It enables the generation and full explanation of the angular distribution of ions transmitted through thin crystals. The angular distribution of the transmitted ions is generated ...
Systematic effects in luminosity measurement at ILC
(Analele Universitatii de Vest din Timisoara, Seria Fizica, 2007)
In order to achieve required precision of luminosity measurement at the International Linear Collider (ILC), that is of order of 10-4, systematic effects have to be understood at the level of this precision. Apart from ...
Rainbows in Channeling of 1 GeV Protons in a Bent Very Short (11,9) Single-wall Carbon Nanotube
(International Journal of Nonlinear Sciences and Numerical Simulation, 2010)
In this work we investigate theoretically the spatial and angular distributions of protons channeled in a bent very short (11, 9) single-wall carbon nanotube. The initial proton kinetic energy is 1 GeV and the nanotube ...
Rainbows with a tilted 〈111〉 Si very thin crystal
(Physics Letters A, 2002)
The angular distributions of protons channeled in a tilted (111) Si very thin crystal together with the corresponding rainbow patterns are considered. The proton energy is 10 MeV while the crystal thickness is 121.1 nm, ...
Geant4-DNA simulation of human cancer cells irradiation with helium ion beams
