Abstract

В статье изложены задачи входного аналитического контроля в экотехнопарках по обработке, утилизации и обезвреживанию производственных отходов, приведена сравнительная характеристика современных методов определения в них содержания металлов и органических соединений, предложены новые подходы к исследованию химического состава жидких неорганических отходов I и II классов опасности на основе применения вольтамперометрии в смешанных водно-органических средах. The article describes the tasks of input analytical control in ecotechnoparks for processing, recycling and neutralization of industrial waste, provides a comparative description of modern methods for determining the content of metals and organic compounds in waste, and suggests new approaches to the study of the chemical composition of liquid inorganic waste of hazard classes I and II based on the use of voltammetry in mixed water-organic media.

Abstract

Technical solution were presented for a foil spectrometer installed on the Globus-M2 and TUMAN-3M tokamaks for measuring the electron plasma temperature. Measurements have been carried out of the time dependence of the plasma temperature in the central region of tokamaks. Using of integrated photodetectors and unique beryllium foils with a thickness of 14-80 μm made it possible to increase the sensitivity of the spectrometer. An important quality of the foils used were the increased values of strength, plasticity, homogeneity, and the absence of surface and internal defects. The combined use of the spectrometer with Thomson scattering diagnostics made it possible to carry out regular temperature measurements in the Globus-M2 tokamak with a high spatial and temporal resolution. The influence of impurities is estimated on the measurement of the electron temperature of the plasma. Keywords: foil spectrometry, tokamak, plasma, continuum, bremsstrahlung, electron temperature, soft-X-Ray, Si-photodiode.

96. The first application of the HIBP diagnostics for co-NBI plasma potential measurement in the TUMAN-3M tokamak

Abstract

The heavy ion beam probe (HIBP) diagnostics at the TUMAN-3M tokamak was updated to provide measurements in the regime with neutral beam injection co-directed with plasma current (co-NBI). By means of HIBP, plasma potential measurements in the center of plasma were carried out. Plasma potential evolution in the discharge with the LH transition (transition to the improved confinement mode) is in good agreement with the concept of negative radial electric field generation during formation of the transport barrier. Keywords: plasma physics, tokamak, heavy ion beam probe, H-mode, neutral beam injection.
