“…The latter statement was based on the low plasma power applied and the light emission observed 66 . Two parallel and vertically aligned Rogowski electrodes were placed at the bottom of the setup 67 , 68 . A voltage difference between these electrodes created an electric field that accelerated the charged particles in a horizontal direction, from which their charge was deducted.…”

The plasma-induced charge of non-spherical microparticles is a crucial parameter in complex plasma physics, aerosol science and astrophysics. Yet, the literature describes this charge by two competing models, neither of which has been experimentally verified or refuted. Here we offer experimental proof that the charge on a two-particle cluster (doublet) in the spatial afterglow of a low-pressure plasma equals the charge that would be obtained by the smallest enclosing sphere and that it should therefore not be based on its geometrical capacitance but rather on the capacitance of its smallest enclosing sphere. To support this conclusion, the size, mass and charge of single particles (singlets) and doublets are measured with high precision. The measured ratio between the plasma-afterglow-induced charges on doublets and singlets is compared to both models and shows perfect agreement with the predicted ratio using the capacitance of the smallest enclosing sphere, while being significantly dissimilar to the predicted ratio based on the particle’s geometrical capacitance.

Variation of Magnetic Fluid Deformation Related to Nanoparticle Concentration in Steady Electric Field

Today, it is important to know the behaviour of magnetic fluids applied in the power electrical machines, e.g. in power transformers, when exposed to an electric field. Besides their promising applications in high voltage engineering, they are of increasing interest from designed assembly and pattern formation point of view. The structure of such magnetic fluids is easily controllable by external magnetic fields. However, less attention has been paid to structural phenomena in magnetic fluids induced by electric fields. The core of this paper is dedicated to the experimental observation of a magnetic fluid droplet deformation in a steady electric field. The mutual relation between the deformation parameter and magnetic nanoparticles concentration is analysed. Spatio-temporal analysis of the droplet shape is presented in the paper. The phenomena of the droplet deformation were recorded by a camera. The detailed experimental procedure is presented. The method of deformation parameter calculation based on the linear pixel as the smallest-size unit in digital image is written. Finally, the relation between the deformation parameter and the nanoparticle volume concentration, as well as the time and magnitude of the DC field application are thoroughly evaluated. The results show that the deformation parameter decreases with increasing concentration at constant applied steady electric field but increases with increasing applied steady electric field.

“…12 The plates of the Tevatron electrostatic separators were designed to provide a field of 6 MV m −1 at distances of 40-60 mm with a length of about 2.5 m. The transverse profile of the Tevatron separators represents a Rogowski profile. 13 For a specific electrode configuration (i.e., plate separation and height), the surface contour of the electrodes is designed to follow the equipotential lines. Such a profile ensures a high homogeneity of the electric field in the flat region between the deflector plates, and, according to Refs.…”
