Abstract

In this study we presented a theoretical investigation of the channeling of high energy protons with the radial deformed (10, 0)@(5, 0) double-wall carbon nanotubes (DWNTs). Proton energy is varied from 0.1 to 10 GeV. The channeling potential within the deformed DWNTs is presented. A Monte Carlo (MC) simulation is used to obtain spatial and angular distributions of channeled protons with radially deformed DWNTs. We treated problem relativistically. This is the first time that we presented spatial and angular distributions of channeled protons with radially deformed DWNTs. Our results show that the spatial and angular distributions depend strongly of nanotube lengths, proton energy, and especially of level of radial deformation of nanotube. Multi-wall nanotubes (MWNTs) can be technically realised with better channeling performance then single-wall nanotubes (SWNTs) and that is why we believe that these results may be useful for production and guiding of nanosized ion beams.

Highlights

IntroductionAfter the discovery of the carbon nanotubes in 1991 [1], a lot of theoretical groups started to work on theoretical modeling and computer simulation of ion channeling through carbon nanotubes [2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29]
For the first time we presented theoretically obtained spatial and angular distributions of channeled protons with radially deformed double-wall carbon nanotubes (DWNTs)
We have analyzed in theoretical manner the channeling of high energy protons through the radial deformed DWNTs(10, 0)@(5, 0)

Summary

Introduction

After the discovery of the carbon nanotubes in 1991 [1], a lot of theoretical groups started to work on theoretical modeling and computer simulation of ion channeling through carbon nanotubes [2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29]. Klimov and Letokhov [2] predicted that carbon nanotubes could be used to channel positively charged particles They modeled ion channeling in GeV energy range. Experimental evidence of ion channeling through carbon nanotubes has been reported by Zhu et al [30]. In the present work we have presented a theoretical investigation of the channeling of high energy protons with the radial deformed (10, 0)@(5, 0) DWNTs. Proton energy is varied from 0.1 to 10 GeV. For the first time we presented theoretically obtained spatial and angular distributions of channeled protons with radially deformed DWNTs. We organized paper in the following way.
