نویسنده
چکیده
The paper presents a description of new Ion Backscattering Beam Line. Small-size electrostatic accelerator “Sokol” with a beam energy range of 0.2...2.0 MeV is used as an ion source. A detail of the Beam Line is using of magnetic spectrometer which allows to carry out precise (several nm) quantitative layer-by-layer non-destructive element analysis of solid composition and structure using Ion Elastic Scattering technique. Design of Backscattering Chamber allows realizing a full set of Ion Beam Analysis techniques. Proton and helium ion backscattering spectra are presented from the thin film samples. Simulated spectra fit well the experimental ones together. The last shows the analytical efficiency of Backscattering Beam Line. PACS: 29.17.+w, 29.30.Ep, 29.30.Aj

Applications of Theory and Experiments to Elastic Scattering in Ion Beam Analysis
The application of theory and experiments to the elastic scattering in ion beam techniques has been investigated. Experimental elastic scattering cross sections for + Ni, p + , Li + Ni, B + Ni and C + I scattering systems have been determined. The optical model and R-matrix analyses have been applied to the experimental data. The calculated cross sections were found to be in very good agreement...
متن کاملImpact of Various Beam Parameters on Lateral Scattering in Proton and Carbon-ion Therapy
Background: In radiation therapy with ion beams, lateral distributions of absorbed dose in the tissue are important. Heavy ion therapy, such as carbon-ion therapy, is a novel technique of high-precision external radiotherapy which has advantages over proton therapy in terms of dose locality and biological effectiveness.Methods: In this study, we used Monte Carlo method-based Geant4 toolkit to s...
