Abstract:

14-GHz electron cyclotron resonance ion source (ECRIS) at the Heavy Ion Research Facility National Laboratory in Lanzhou has been used to investigate the radiative deexcitation of highly charged Ar 17+ and Ar 16+ ions as they interact with a molybdenum surface. The interaction of Ar 17+ and Ar 16+ ions above Mo Metallic Surface has been studied by looking at the X-rays with a Si ( Li ) detector. ECRIS is used in our work for the first time. As the experimental results, the X-ray spectra of Ar 17+ and Ar 16+ ions interacting with a Mo metal target have been given. The capture of many electrons

Abstract:

In the present work, mechanisms of Ar K X-ray production have been investigated under low-energy Arq+ + Ar collisions in a wide range of the ion-charge states. Ar K X-rays have been observed as a function of the collision energy over (0.753.75)q keV/u and of the charge state over q = 816 of projectile Arq+ ions. If the L-shell vacancies become available (q = 9), Ar K X-ray yields are found to be enhanced roughly three orders of magnitude, compared with Ar8+ ions with no L-shell vacancy; to show some threshold; and to tend to quickly saturate at higher collision energies. The present analysis

Abstract:

We investigated THz emission from Ar-ion-implanted Cu(In,Ga)Se2 (CIGS) films. THz radiation from the CIGS films increases as the density of implanted Ar ions increases. This is because Ar ions contribute to an increase in the surface surge current density. The effect of Ar-ion implantation on the carrier dynamics of CIGS films was also investigated using optical pump THz probe spectroscopy. The fitted results imply that implanted Ar ions increase the charge transition of intra-and carrier–carrier scattering lifetimes and decrease the bandgap transition lifetime.

Abstract:

The time-of-flight (TOF) spectra of Ar+ and Ar fragments produced in the photodissociation of Arn+ (3 ≦ n ≧ 24) were measured at wavelength around 540 nm. The kinetic-energy and angular distributions of the neutral photofragments were obtained for n = 3, 9 and 24 by a simulation analysis of the measured TOF spectral profiles. The overall aspect of the photodissociation process of Arn+ is deduced from these distributions within the context of trimer ion core model; a linear Ar3+ core is solvated by neutral Ar atoms. For Arn+ with 4 ≦ n ≲ 14, direct dissociation of the Ar3+ chromophoric core giv

In this work, a reaction mechanism of formation of noble gas (Ng) cluster ions has been theoretically investigated in detail. The kinetic studies of formation of Xe+Xe cluster in Xe, Ar+Ar cluster ions in Ar, and Ne+Ne cluster ions in Ne have been made as theoretically. The optimized structures in the ground state were calculated using the density functional theory (DFT) by the B3LYP method combined with the Stuttgart/Dresden effective core potential basis set (SDD). In addition, we calculated the rate constants of all cluster formations. The results are 1.15 × 10−31, 3.58 × 10−31, 0.23 × 10−3

The reliability of the model is first verified by comparing the calculated results with the experimental data, and the consistent results are obtained. Then, the spatial distributions of the charged species densities are investigated. As Ar fraction decreases, the maximum densities of charged particles shift toward the coil significantly, and the O2+ becomes the dominant positive ion at higher O2 fractions. The main reactio

Abstract We have studied to enhance efficiency of producing multicharged ions in an electron cyclotron resonance ion source (ECRIS). The gas mixing method is known as an empirical method for highly efficient production of multicharged ions. This method is to mix low Z gas into the multicharged ions plasma. There are various explanations for the gas mixing effect. One of them is the ion cooling effect. It is necessary to obtain parameters related to the ion temperature in order to experimentally confirm the effect. We measured emittances for ion beams by using a wire probe and a multi-slit. He

Abstract The effect of inert gas ions with different atomic masses (Ar+, Xe+) on the magnetoresistance of Co90Fe10/Cu superlattices deposited on a silicon substrate has been investigated by comparison. The Ar+ ion irradiation has been found to decrease the magnetoresistance more significantly than Xe+ ion irradiation, which seems to be due to a larger average projective range for Ar+ (Rp = 5–6 nm) than that for Xe+ (Rp = 3.3–4.3 nm) and, accordingly, a greater depth of the atom mixing zone (∽(2–3)×Rp) when ions move from the top layers of the superlattice toward the substrate.

Abstract:

HfO2 thin films were deposited on BK-7 glass substrates using an electron beam evaporation deposition (EBD) technique and then post-treated with argon and oxygen ions at an ion energy ranging from 800 to 1200 eV. The optical properties, laser damage resistance, and surface morphology of the thin films exposed to Ar ions and O2 ions at various energies were studied. It was found that the two ion post-treatment methods after deposition were effective for improving the LIDT of HfO2 thin films, but the mechanism for the improvement differs. The dense thin films highly resistant to laser damage can

Abstract:

In this work, the projected range, the nuclear stopping power(Sn), electronic stopping power (Se), vacancies, replacement collisions, and total target damage of β-Ga2O3 by H, He and Ar ion bombardment are investigated by the Monte Carlo SRIM software. The ions were vertically incident on a 1-um β-Ga2O3 material, and their energies varied from 100 keV to 1 MeV. The results showed that the projected range increased for all three ions with increasing incident energies, with H ions having the largest projected range. The Sn for Se with incident energy of 0-1MeV in β-Ga2O3 is much greater than the

ABSTRACT: Mammalian spermatozoa must undergo an exocytotic event during fertilization, the acrosome reaction (AR). In most species studied this process is induced by specific glycoproteins of the oocyte extracellular matrix, the zona pellucida (ZP), and it involves guanine nucleotide‐binding regulatory proteins (G‐proteins), resulting in an uptake of extracellular calcium by the sperm. In the bull, this event has been reported to be mediated by voltage‐dependent calcium channels (VDCC). Previous observations showed that neoglycoproteins (NGPs) with N‐acetylglucosamine or mannose (GlcNAc‐BSA or

Abstract:

The relationship between the defect structure and luminescence property of ZnO ceramics implanted with Ar of 2×1015 – 60×1015 ions/cm2 was studied. After annealing, the heavy dose-implanted sample (Ar ≥ 30×1015 ions/cm2) was characterized by a luminescence peak at the 730-nm wavelength. Defects in the implanted region formed voids during post-annealing. Oxygen tracer experiments indicated that grain boundary diffusion in the implanted region was enhanced significantly.

Abstract:

Abstract Highly charged ions (HCIs) are currently utilized in numerous fundamental and applied sciences, including astrophysics, dark matter search, optical clocks, semiconductor lithography, and quantum dot fabrication, to name just a few examples. At Ulsan National Institute of Science and Technology (UNIST), a tabletop electron beam ion trap (EBIT) has been developed for creating and studying HCIs. The UNIST-EBIT compresses the electron beam by 72 permanent magnets (up to 0.84 T) and produces up to He-like Ar ions. The primary objective of the UNIST-EBIT is to obtain X-ray spectrum data ess

The purpose of this study was to examine the anti-oral microorganism effects of fluorine and/or silver ions implanted into acrylic resin (PMMA) using plasma-based ion implantation (PBII) with argon gas. The experimental PMMA specimens were implanted with F and Ag ions alone or simultaneously by the PBII method using Ar or Ar/F2 gases and Ag mesh. The surface characteristics were evaluated by X-ray photoelectron spectroscopy (XPS), contact angle measurements, and atomic force microscopy (AFM). Moreover, the antibacterial activity against Streptococcus mutans (S. mutans) and the antifungal activ

Abstract:

Thick targets of Li2B4O7 containing different concentrations of S have been irradiated with 0.8 to 3.0 MeV protons and 1.0 to 5.0 MeV Ar ions and the K X-ray yields of the S and one projectile (Ar) measured. The K X-ray production cross sections deduced from the measured yields, show a strong dependence on the S concentration in the case of the Ar bombardments. This effect is interpreted as being a consequence of the double-scattering mechanism occurring in the Ar-S collision system.
