Optical properties of the 127 degrees cylindrical energy analyzer used in LEIS experiments
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2002)
The optical properties of the 127degrees cylindrical energy analyzer used in low energy ion scattering (LEIS) experiments are studied by means of SIMION 3D version 6.0 program. The dependence of the acceptance solid angle ...
The influence of orientation on the radiation-induced crosslinking/oxidative behavior of different PEs
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2007)
This paper studies the influence of orientation and structural peculiarities on the radiation-induced oxidation/crosslinking changes in different polyethylenes (PEs). For this reason, low density polyethylene (LDPE), linear ...
Channeling of protons through BN nanotubes
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2015)
In this paper we study the angular and spatial distributions of protons channeled through boron-nitride (BN) nanotubes. The BN nanotubes have very similar structures like carbon nanotubes, but they are more thermally and ...
Second-order theory of helical hexapole lens of infinite length
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2007)
Expressions which can be used to calculate the focusing coefficients applicable to the interior regions (no fringe fields) of magnetic helical hexapole lenses of infinite length have been derived through second-order. It ...
Instrumental function of the SPECS XPS system
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2017)
A simple method for the energy resolution measurement of a spectrometer, working in the fixed analyser transmission mode, is proposed and used to determine the resolution of a SPECS Phoibos 100 spectrometer, being a part ...
Analysis of thermoluminescence kinetics of Mg2SiO4:Tb compounds employing an interactive model
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2009)
The kinetics involved in the thermoluminescence (TL) of Mg2SiO4:Tb compounds has been investigated by unfolding glow curves employing both the General Order model and a model that takes into account interactions among ...
Antiproton therapy
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2008)
Radiotherapy is one of the most important means we have for the treatment of localised tumours. It is therefore essential to optimize the technique, and a lot of effort goes into this endeavour. Since the proposal by Wilson ...
High precision measurements of forbidden transitions in highly charged ions at the Heidelberg EBIT
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2005)
Few-electron ions, which can be produced and studied at rest in electron beam ion traps (EBITs) are very well suited for the study of nuclear size effects and QED in strong fields, but the various contributions are usually ...
Electron transmission through a macroscopic platinum capillary
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2017)
We present simulations for electron transmission through a platinum macrocapillary (diameter d = 3.3 mm, length l = 48 mm) using classical transport theory. Both elastic and inelastic scattering events of primary electrons ...
Biological effectiveness of antiproton annihilation
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2004)
We describe an experiment designed to determine whether or not the densely ionizing particles emanating from the annihilation of antiprotons produce an increase in biological dose in the vicinity of the narrow Bragg peak ...
