[en] One of the most attractive applications of Auger electron spectroscopy (AES) at solid surfaces is the combination of elemental analysis with high lateral resolution. Thus, a solid surface can be imaged in the 'light' of electrons originating via the Auger effect from a distinct kind of atoms with characteristic kinetic energies determined by the individual atomic energy levels involved in the excitation process. Laterally resolved AES may also deliver information about the variation of chemical binding states across the sample surface via a 'chemical shift' of the respective atomic energy levels.

[en] During high power transmission in waveguides (P=1 - 10kW/cm²) of radio frequency waves, strong outgassing may be observed. This outgassing can be due to breakdowns or, for long pulse shots, to a thermal baking of the waveguide walls provided by the RF losses. Breakdowns depend strongly on surface state, namely on secondary electron emission coefficient and also on adsorbed molecules coverage. During the conditioning phase, outgassing flux varies between 10^-3T.l/s and 10^-1 T.l/s per breakdown. RF losses-induced outgassing may be very large for long pulses (t_RF>30 s): for a 63 s pulse, ultimate outgassing rate laies between 10^-8T.l.s^-1 cm^-2 and 10^-5T.l.s^-1.cm^-2. These strong variations are related to initial treatment and RF conditioning. The 'global' activation energy is found to be relatively constant after a few RF shots (near 23 kcal/mole)

[en] A systematic investigation of the influence of base-alloy composition on the corrosion fatigue life, cyclic strength, thermal fatigue life and thermal stabilities of PVD metal and metal-ceramic coatings has been conducted for a series of Ni-base superalloys differing in their phase composition. The coatings were evaluated by optical and microprobe analyses. Microhardness tests were also conducted to characterize the hardness and mechanical integrity of various coating layers.

[en] Auger-electron spectroscopy (AES) is one of the most widely used techniques for surface characterization. There are two principal areas of applications. The first application area (and by far the largest use) of AES is in the measurement of the near-surface composition of solids. The second application area involves the use of AES for probing the electronic structure of surfaces. This article is a brief overview of how AES is employed in these two applications.

[en] The paper examines the influence of surface area, materials, chemical cleaning and baking on outgassing of large vessel (i.e. over 1 cu. m and well over 1 sq. m) used for cyclotrons, Tokamak, etc

[en] Auger first experiences in 1923 and thesis in 1926 on photoelectrons with a Wilson chamber are shortly presented. The two related techniques, Siegbahn XPS (X-ray Photoelectron Analysis) and Auger AES (Auger Electron Spectroscopy), are compared for surfaces analysis with advantages and disadvantages.

[en] Recently the PCVD process for a-B/C:H films was successfully used in the nuclear fusion devices for protection their inner walls from hydrogen plasma erosion. In this paper we describe the PCVD process for analogous films but not from toxic, explosive or selfignitional gaseous mixtures used before. We suggest as the safe precursor the vapours of the solids and in this case there is no necessity in special safety precautions. The composition, structure and properties of such films are characterized properly by different methods. The accessibility of new method which is similar in many features to that for a-C:H coatings and promising combination of properties point out the perspectives for using the a-B/C:H films in different thin film technologies
