An experimental stand for studies of electric arc, electrode erosion and insulator degradation processes in high-current circuit breakers and some preliminary experimental data is described. The setup includes a discharge chamber, a capacitive energy storage with capacitance of 0.11 F, voltage up to 10 kV, and all necessary diagnostic techniques. The stand is designed for modeling current pulse with amplitude of 3–150 kA and duration of the first half period of 1.0–3.0  ms during the process of disconnecting the ring and the pin contacts. The arc is cooled by transverse gas blowing at pressure in the chamber of 0.5–3 MPa. Acquired experimental data can be used for verification of the modelling results of the heat transfer processes in the discharge chamber. At the stand, advanced composite materials based on carbon and iron-copper pseudoalloy are studied.

Data Processing Technique

The Pulsed Neutron Source (PNS) experiment on the Fast-thermal Coupled sub-critical core VENUS-1# has been performed in CIAE with 14MeV accelerator neutron source. The preliminary experimental data indicated spatial dependence of prompt neutron attenuation constant α, which is conflict to traditional theories. To re-evaluate the experiment and probe possible special features of the Fast-thermal Coupled core, a Monte-Carlo simulation of PNS experiment has been performed in this paper. Considering Contamination of harmonics mode of prompt neutrons, a data-processing technique, e.g. harmonics filtering, is used to obtain the fundamental mode decay. The simulated results indicate that, the influence of harmonics and external source are mainly in the time region 0∼500μs after pulsed neutron injection; by harmonics filtering, spatially independent α values are obtained and verified. By the method above, the experimental data are re-processed, however, the problem of the spatially dependence of α is not improved at all, the α value indicated by detector R is still quite different from others’. The works performed in this paper suggest that, some future PNS experiments should be deployed to confirm the experimental phenomenon.

In order to investigate interdiffusion in Mo/V multilayers, we present a method that combines both kinetic mean-field simulations and calculations of x-ray scattered intensity with disorder effects. Considering preliminary experimental data obtained on Mo(4nm)/V(2nm) multilayers, we show that the angular shift of spectra observed after annealing, should take place for both Fickian and asymmetric interdiffusion modes. In contrast, clear signatures of the interdiffusion modes are found from the simulation of the peak intensities. These results offer interesting perspectives for a full analysis of the interdiffusion in these systems.

Abstract There is great interest in the search for multifunctional waste-based materials that may be applied as environmentally friendly adsorbents. Iron-rich sludge from ground drinking-water treatment plants may be considered a potential adsorbent for various water contaminants. This material is generated during ground water purification because of the excess of metal ions in water (Fe, Mn). In practice, this sludge is frequently disposed of as waste material and, so far, is not commonly applied as the adsorption base. Our research aims to explore the adsorption potential of iron sludge for selected synthetic dyes, including malachite green, ponceau 4R, and brilliant blue FCF. Experimental data were performed using iron sludge collected from the Groundwater Treatment Plant in Koszalin, Poland, and comparing it with adsorption properties of commercial activated carbons (Norit SA Super and Norit CA 1). The kinetics, adsorption isotherms, and temperature influence on the removal of target dyes were investigated and discussed. Preliminary experimental data have revealed that iron sludge can be considered an adsorbent for the removal of cationic dyes.
