AB  - The broad maximum in the energy spectra of Ar+ ions scattered from the clean metal surfaces to the scattering angles smaller than 90degrees is studied. Besides the Ar+ ions, other ion species (He+, N+ and Ne+) are also used as projectiles. The targets in the experiments were polycrystalline silver and copper as well as the monocrystalline nickel (110). According to the analysis of the obtained energy spectra, the maximum is interpreted as the consequence of the symmetric binary collisions between the Ar+ projectiles and the former implanted Ar atoms placed under the outermost atomic layer. This type of experiments gives a unique opportunity to study the process of low energy Ar+ ions implantation in real time, and it could be extended to other projectile-target systems of the greater technological interest.

AB  - 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 Omega on the target plane coordinates (x,y) and the relative particle energy epsilon completely describes the optical properties of an analyzer. The Omega(x, y, epsilon) function is calculated from the computed trajectories of ions emitted from different points of the target plane. The influence of spherical aberrations to the error in the energy measurement is determined experimentally. The experimental results agree very well with the results obtained using the numerical simulations as well as, with the results obtained by means of the second order analytical approach. The optical properties are analyzed for different electrode potential configurations i.e. for different deflection voltage modes defined according to the potentials of the inner and the outer electrode. The applied deflection voltage mode does not change Omega(x,y,epsilon) significantly. However, there is an important influence of the deflection voltage mode to the analyzer constant due to the acceleration of ions traversing along the optical axis of the analyzer. The knowledge of Omega(x, y, epsilon) can be used to determine the dependence of the energy spectra on the optical properties of the analyzer as well as, on the primary beam profile. This is of particular interest in the analysis of LEIS spectra, because deviation of spectra caused by the optics of the analyzer can be a source of significant errors in quantitative surface composition analysis.

AB  - A new concept of a multipurpose device for the investigation of a low energy in beam interactions with solid state surfaces is realized in an apparatus for surface analysis by means of low energy ion scattering (LEIS), direct recoil spectrometry (DRS), mass spectrometry of recoil ions (MRSI), and secondary-ion mass spectrometry (SIMS). This device provides broad alkali ion beams, homogeneous and much more intense than in standard commercial realizations available, as well as various high quality intense gas ion beams. A long tube with a magnetic quadrupole triplet is introduced. This construction disjoins the high vacuum from the ultrahigh vacuum (UHV) parts of the system and makes possible low cost differential pumping. The use of an UHV broad alkali ion beam in SIMS experiments should importantly decrease crater effect problems without use of rastering and electrical gating systems. In order to demonstrate the possibilities and the advantages of the proposed concept, we present the results of experimental analysis of primary ion beam characteristics, as well as LEIS and DRS experimental results obtained by use of gas ion beams scattered from silver polycrystalline surfaces. This design concept results in a simple and low cost device with operating characteristics comparable to those of high quality devices of similar type. (C) 2000 American Institute of Physics.

AB  - A new broad-beam ion source of alkali (K+) ions for use in ultra high vacuum was designed, built and tested. The basic principles used have advantages over gas-fed broad-beam ion sources, because there is no need for differential pumping, and because an intrinsically pure ion beam obviates the necessity for charge-to-mass analysis. The source is based on the effect of thermionic emission of K+ ions from solid potassium aluminosilicate (K2O . Al2O3 . 2SiO(2)) emitter. An ion beam current of 0.4 mA has been achieved at an extraction voltage of 3.5 kV with 1.5 cm beam diameter. The degassed broad-beam ion source in operation does not appreciably influence the background pressure in the ultra high vacuum system.
