AB  - The mVINIS ion source, a part of FAMA installation at Vinca Institute of Nuclear Sciences, is able to produce multiple charged heavy ion beams through the utilization of vapors created by the process of melting solids inside the miniature oven (mini-oven). The mini-oven that was used previously could only reach the maximum temperature of 800?C, which is far too low for evaporating most metals. For this purpose, a higher operating-temperature of 1500?C was needed. Our study focuses on numerical finite element method analysis of the temperature distribution of newly designed mini-oven.

AB  - Chitosan and its modified forms have received great attention as potential adsorbents due to its outstanding adsorption characteristics toward removal of vaious toxic heavy metal ions from aqueous solutions. In this work, a porous chitosan hydrogel beads (CHB) and CHB cross-linked with glutaraldehyde (GLA) and citric acid (CA) were synthesized and used for investigation of its adsorption performances toward the removal of Pb(II), Cu(II), Zn(II), Cd(II) and Cr(VI) ions from water in batch and dynamic systems. Maximum removal was achieved in the pH ranges of 4.0 - 6.5 and 2.0 - 3.5 for divalent cations and Cr(VI) oxyanion, respectively. The equilibrium adsorption data were best fitted by the Langmuir isotherm model. Based on the optimal conditions, the fixed-bed breakthrough curves for the removal of the studied metal ions from the aqueous solutions using fixedbed columns were experimentally evaluated, as well as theoretically predicted using COMSOL Multiphysics software.

AB  - This paper considers the transmission of the initial parallel proton beam with kinetic energy of 10 keV through the electrostatic oelopole lens. The spatial rainbows and corresponding proton distributions are calculated by using the infinite length approximation potential. Positive potentials of the lens electrodes are set to be 0.35 kV and 9 kV. It has been shown that by application of catastrophe theory, the generating function for mapping proton positions between entrance and exit transverse plains can be determined, giving accurate rainbow patterns for biasing potentials of 0.35 kV. © 2018; Vinca Inst Nuclear Sci.

AB  - 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 to the first one. The propagation of a proton beam with a kinetic energy of 10 keV through the doublet is in the focus of our analysis. The potential of the electrodes of both lenses is 2 kV. The electrostatic potential and the electric field components of the lens doublet are calculated using a 3-D computer code based on the method of moments. Spatial and angular distributions of protons propagating through the lens doublet, as well as the parameters defining beam quality, are investigated. As in the case of the single square electrostatic rainbow lens, the evolution of these distributions is determined by the evolution of corresponding rainbow lines, generated by the use of the theory of crystal rainbows. Our study shows that a beam core in the shape of a cusped square is formed by the spatial rainbow line that appears first. This rainbow line occurs during proton propagation through the first lens. The beam core retains the cusped square shape during the propagation through the second lens. The electrostatic field of the second lens causes the appearance of an additional spatial rainbow line, which encompasses the beam core and defines the outer border of the beam. This rainbow line constitutes the main difference between the cases of the lens doublet and a single lens.

AB  - This review paper is devoted to transmission of protons through rainbow lenses, being novel ion beam optical elements analogous to crystal channels. We begin with a brief description of the crystal rainbow effect, which has proven to be the basic effect in ion channeling in thin crystals. Then, we concentrate on the transmission of a parallel proton beam through a square electrostatic rainbow lens. The initial proton kinetic energy is 10 keV and the potential of the electrodes is chosen to be between 10 and 100 kV. It is demonstrated that the evolution of the spatial distribution of transmitted protons is determined by the evolution of the corresponding rainbow pattern. The beam after the lens is clearly separated into the bright and dark components, corresponding to the bright and dark sides of the rainbow, respectively. All the focused protons are confined within the rainbow line. After that, we explore more accurately the focusing properties of the same electrostatic rainbow lens. This is done with the parallel and nonparallel initial beams of the kinetic energy of 10 keV. The electrode potential is chosen to be 2 kV. In the continuation of the paper, we analyze the acceleration properties of a square radiofrequency rainbow lens. This is done with a nonparallel initial beam of the kinetic energy of 10 keV. The lens electrodes excitation potential is a harmonic function of time of the amplitude of 20 keV and frequency of about 3 MHz. We explain the spatial, angular, and kinetic energy distributions of protons propagating through the lens. The transmitted proton beam contains a squarelike core, which is defined by the focused protons. Finally, we discuss the possible applications of rainbow lenses.

AB  - У oвoј дисертацији проучаване су просторне и угaoнe расподеле протона, енергије 10 keV, и њихове одговарајуће линије дуге у случају квадратног електростатичког дугиног сочива. Просторне и угaoнe расподеле протона дoбиjeнe су нумeрички рeшaвaњeм њихoвих jeднaчинa крeтaњa и коришћењем мeтoде кoмпjутeрскe симулaциje. Линије дуге су такође одређене нумерички. Сем тога, испитивано је какав утицај имају одговарајуће линије дуге на трансмисију снопа кроз сочиво и након изласка из њега.Анализиран је модел дугиног сочива, у коме је коришћена аналитичка апроксимација електростатичког поља сочива, и анализиран је уређај дугиног сочива, код кога је коришћено реалистично електростатичко поље сочива, које је добијено нумерички. У случају модела дугиног сочива претпостављено је да је почетни сноп протона паралелан, док је у случају уређаја дугиног сочива почетни сноп протона био паралелан и квази-паралелан.У случају модела дугиног сочива, изучаване су просторне и угaoнe расподеле протона и одговарајуће линије дуге, када је напон на електродама био 10, 20, 50 и 100 kV. У случају уређаја дугиног сочива показано је да се просторне и угаоне линије дуге јављају за много мање вредности напона на електродама сочива у поређењу са моделом дугиног сочива. Наиме, затворене просторне линије дуге унутар сочива и затворене угаоне линије јављају се за напоне на електродама сочива од 2 kV. Ово може да има велики практични значај пошто је много једноставније реализовати и радити са напонима на електродама сочива од 2 kV него са нпр. напонима на електродама од 100 kV.Показано је да електростатичко дугино сочиво има карактеристична катастрофична фокусирајућа својстава која су одређена одговарајућим vпросторним и угаоним линијама дуге. На основу тога може се закључити да би се дугино сочиво могло успешно користити за препарацију и транспорт јонских снопова у постројењима за њихово убрзавање, укључујући њихову препарацију за међусобне сударе јонских снопова, као и за добијање добро дефинисаних профила снопова, који би се могли користити у физици чврстог стања, биофизици, археологији и геологији.
AB  - In this dissertation, the spatial and angular distributions of 10 keV protons and the corresponding rainbow lines are investigated in the case of the square electrostatic rainbow lens. The spatial and angular proton distributions were obtained numerically by solving proton’s equations of motion and applying the computer simulation method. The rainbow lines were also determined numerically. Besides, influence of the corresponding rainbow lines on the transmission of the beam through the lens and in the space behind is investigated.The rainbow lens model, which uses analytical approximation of the electrostatic field of the lens, and the rainbow lens device, which uses numerically obtained realistic electrostatic field of the lens, have been analyzed. In the case of the rainbow lens model, the parallel initial proton beam was assumed, while in the case of the rainbow lens devise, the initial proton beam was parallel and quasi-parallel.In the case of rainbow lens model, the spatial and angular distributions and the corresponding rainbow lines have been analyzed, for the electrode voltage equal to 10, 20, 50 and 100 kV. In the case of the rainbow lens devise, it is shown that the spatial and angular rainbow lines occur for a much less values of the electrode voltage. Namely, closed spatial rainbow lines inside the lens and closed angular rainbow lines occur for the electrode voltage equal to 2 kV. Practically this could be very important since one can build and work more easily with the electrode voltage of 2 kV than e.g. with the electrode voltage of 100 kV. viiIt has been shown that the electrostatic rainbow lens has characteristic catastrophic focusing behavior, which is determined by the corresponding spatial and angular rainbow lines. As a result, the rainbow lens could be successfully used for preparation and transportation of ion beams within accelerator facilities, including their preparation for collisions with each other, as well as, for obtaining well defined beam profiles that could be used in condensed matter physics, biophysics and geology.

AB  - In this work, we study the silicon amorphization dependence on the crystal depth induced by 6-MeV Al2+ ions implanted in the LT 110 GT and randomly oriented silicon crystal channels, which was not directly experimentally accessible in the previous similar high-energy ioncrystal implantation cases. Accordingly, the micro-Raman spectroscopy scanning measurements along the crystal transversal cross section of the ion implanted region were performed. The ion fluence was 10(17) particles/cm(2). The scanning steps were 0.2 and 0.3 mu m, for the channeling and random ion implantations, respectively. The obtained results are compared with the corresponding Rutherford backscattering spectra of 1.2-MeV protons in the random and channeling orientations measured during the channeling implantation. Additionally, scanning electron microscope picture was taken on the transversal cross section of the implanted region in the channeling implantation case. We show here that the obtained silicon amorphization maxima are in excellent agreement with the corresponding estimated maxima of the aluminum concentration in silicon. This clearly indicates that the used specific micro-Raman spectroscopy scanning technique can be successfully applied for the depth profiling of the crystal amorphization induced by high-energy ion implantation.

AB  - This paper is devoted to the focusing properties of a square electrostatic rainbow lens, which is a novel ion beam optical element. We consider the transmission of parallel and non-parallel proton beams of the initial kinetic energy of 10 keV through this lens. The potential of the electrodes of the lens is chosen to be 2 kV. The electrostatic potential and components of the electric field in the region of the lens are calculated using a three-dimensional finite element computer code. We investigate the spatial and angular distributions of protons propagating through the lens and in the drift space after it. It is confirmed that the evolutions of these distributions are determined by the evolutions of the corresponding rainbow lines, generated using the theory of crystal rainbows. The beam is separated into two components. One beam component, appearing as a beam core, is generated dominantly by the focused protons. Its boundary line in the transverse position plane can be very well approximated by a hypotrochoid. The other beam component is generated dominantly by the defocused protons. We present the focusing coefficient of the lens, the confining coefficients of the lens for the focused and defocused protons, the density of the beam core, the vertical or horizontal emittance of the beam core, and the brightness of the beam core.

AB  - The subject of this paper is the transmission of protons through a square electrostatic rainbow lens, which is similar to a quadrupole electrostatic lens and analogous to a crystal channel. The potential of the electrodes is chosen to be 10, 20, 50 and 100 kV. The initial proton kinetic energy is 10 keV. It is shown that the interaction potential between the proton and lens is purely anharmonic. We explore the spatial distributions of transmitted protons inside the lens and in the drift space after its exit. It is demonstrated that the evolution of the spatial distribution is determined by the evolution of the corresponding rainbow pattern. The proton beam after passing through the lens is clearly separated into the bright and dark components, which correspond to the bright and dark sides of the rainbow, respectively. All the focused protons are confined within the rainbow line. This effect is called the catastrophic ion beam focusing. We also explore the angular distributions of transmitted protons at the lens exit. The corresponding rainbow patterns appear only when the potential is 50 and 100 kV. In these cases almost all the focused protons are confined within the rainbow line. This means that the lens enables one to create a proton beam core, which includes the protons focused in both the transverse position plane and the transmission angle plane. The evolutions of the focused and defocused groups of protons are analyzed quantitatively via three parameters - the focusing coefficient of the lens, and the confining coefficients of the lens for the focused and defocused protons. Finally, we discuss the possible applications of the lens.

AB  - In this work we study the angular distributions of 1 GeV protons channeled in long (10,10) single-wall carbon nanotubes. The nanotube length, L, is varied between 10 and 100 mu m. The angular distributions of channeled protons are obtained using the numerical solution of the proton equations of motion in the transverse plane and the Monte Carlo method. The effects of proton energy loss and scattering angle dispersion caused by its collisions with the nanotube electrons are taken into account. Analysis shows that for L LT 30 mu m, the transverse structure of the nanotube could be deduced from the angular distribution. For L GT = 40 mu m, the angular distribution contains the concentric circular ridges whose number increases and the average distance between them decreases when L increases. A possible application of the obtained results for characterization of carbon nanotubes is discussed.

AB  - We have studied theoretically the angular distributions of 1 GeV protons channeled through the long (10, 0) single-wall carbon nanotubes. The nanotube length is varied between 10 and 80 mu m. The angular distribution of channeled protons is generated by the computer simulation method using the numerical solution of the proton equations of motion in the transverse plane. The analysis shows that for the nanotube length less then 30 mu m the transverse geometrical structure of the nanotubes could be deduced from the angular distribution. For the length over 30 mu m, the angular distribution is characterized only by the concentric circular ridges. The number of ridges increases and the distance between them decreases as the nanotube length increases. For the nanotube length of 80 mu m, the circular ridges are no longer visible and the angular distribution becomes equilibrated.

AB  - In this work we investigate the rainbows appearing in channeling of 1 GeV protons through the long (11, 9) single-wall carbon nanotubes. The nanotube length is varied from 10 to 500 pm. The angular distributions of channeled protons are computed using the numerical solution of the proton equations of motion in the transverse plane and the Monte Carlo method. The rainbows are identified as the rings in the angular distributions, which correspond to the extrema of the proton deflection functions. Each rainbow is characterized by a sharp decrease of the proton yield on its large angle side. As the nanotube length increases, the number of rainbows increases and the average distance between them decreases in an easily predictable way. When the average distance between the rainbows becomes smaller than the resolution of the angular distribution, one cannot distinguish between the adjacent rainbows, and the angular distribution becomes equilibrated. We call this route to equilibration the rainbow route to equilibration. This work is a demonstration of how a simple one-dimensional bound dynamic system can exhibit a complex collective behavior.

AB  - U ovom radu analizirane su ugaone raspodele protona energije 1GeV kanalisanih kroz jednoslojnu ugljeničnu nanocev tipa (11, 9). Dužina nanocevi je menjana od 10 do 100 µm. Ugaone raspodele su dobijene pomoću numeričkih rešenja jednačine kretanja u transverzalnoj ravni nanocevi i metode Monte-Karlo. Za potencijal interakcije proton-ugljenik uzeta je Molijerova aproksimacija Tomas-Fermijevog potencijala. Dobijeni rezultati su veoma interesanti: ugaone raspodele su karakterisane sa oštrim stepenastim maksimumima, čiji se broj linearno povećava a njihovo međusobno rastojanje eksponencijalno smanjuje sa povećanjem dužine nanocevi. Ovi rezultati mogu biti iskorišćeni za karakterizaciju kiralnih nanocevi pomoću snopova protona.
