[en] An equipment has been designed to extend the scope of control of ion beam flux for an intensive ion beam source used for plasma injection in magnetic vessels. The control equipment is connected to the electromagnet power supply. A consumption regulator is fitted in the operating gas supply to the hollow cathode of the ion source. A circuit is also included for discharge voltage maintenance consisting of a control element and a discharge voltage pick-up. (M.D.). 1 fig

Ar⁺ and Xe⁺ ion beams treatment of Ni- and Fe-base structural alloys

Grigoryan, V.G.; Dal'skij, A.A.; Pastukhov, K.M.; Sulima, A.M.; Yagodkin, Yu.D.1990

AbstractAbstract

[en] Methods of electron Auger-spectroscopy, secondary ion mass-spectrometry, scanning electron microscopy and x-ray structural analysis as measurements of the surface roughness have been employed to study the surface layer state of Ni- and Fe-base structural alloys before and after the Ar⁺ and Xe⁺ ions irradiation with energy of 0.4-1.5 keV with the ion current density j=0.1-1 mA/cm². It is found that the irradiation decreases drastically the surface layer depth with an altered (as compared with the bulk) chemical composition, favours relaxation of residual technological stresses. The surface topography obtained as a result of the irradition depends on the structure of the treated material and the irradiation regimes

Estimation of the average response on spectra of strong earthquakes based on empirical data

Grigoryan, V.G.2021

AbstractAbstract

[en] The previously obtained correlation equations between the response spectra and the focal parameters of strong earthquakes made it possible to construct the average (standard) spectra of impacts for the given values of magnitudes and ranges of epicentral distances. The obtained average (standard) spectra [RA] can be considered preliminary design models of seismic event. Having made further possible refinements and corrections based on regional characteristics, it will be possible to use the latter as basic models of expected seismic impacts for direct use
