Using electric field induced second harmonic generation (E-FISH), we performed direction-resolved absolute measurements on single-channel streamer discharges in 70 mbar (7 kPa) air with 0.2 mm and 2 ns resolutions. In order to obtain the (local) field, developed a deconvolution method taking into account phase variations of E-FISH. The acquired distribution shows good agreement simulation results under same conditions, direction, magnitude, shape. This is first time that E-FISH applied...
Abstract The electric field is the driving force behind every plasma. Electric induced second harmonic generation (E-FISH) a diagnostic able to obtain with high temporal and spatial resolution, considered non-invasive can be applied almost any type of plasma sensitivity. However, fluence laser beam used as probe in this technique, interact gas induce charges, which subsequenly influence In work, E-FISH on non-thermal pulsed jets N2 flowing into atmospheric air. these jets, ionization fronts...
Higher engineering education programmes increasingly include courses characterised by real-world problems and student collaboration in multidisciplinary teams. Research findings demonstrate that students remain limited perceiving meaningfully bridging disciplinary differences these course contexts. Drawing on the literature boundaries boundary interactions, this study sought to investigate how applied physics mechanical managed their a challenge-based learning course. Using qualitative, case...
In high tech equipment involving voltages, such as switchgear, surface charging of solid dielectrics can significantly affect the performance. A Pockels-effect based technique is proposed a promising diagnostic for its capability to create 2D charge map in real time. However, characterization and comparison performance most commonly used Pockels setup configurations missing existing literature, which makes it difficult choose best configuration specific task. To overcome this limitation,...
Surface charging of solid dielectrics poses challenges in industry. To investigate the dynamics these charges, a tool for quantitative and spatially controlled surface charge deposition is desired. However, existing techniques lack possibility local deposition. This paper presents technique at atmospheric pressure using an X-ray ionizer. A mask introduced to enable charging. The accumulation studied with electrostatic voltmeter. based proves be highly repetitive: only 1 % variation potential...
