[Show abstract] [Hide abstract] ABSTRACT: Was discovered the formation of structures consisting from structures of clusters in dusty plasma at a temperature of liquid nitrogen. The dependence of the reduced electric field E/N in the positive column of a discharge from gas temperature was experimentally measured. Depending on the pressure of neon were observed the different structural transitions in the regions of growing current-voltage characteristics at low discharge currents 0.01≤ I ≤ 1 mA. Were determined the three specific regions of structural transitions. In the region 1 there appear the ordered structures with the lattice similar to the hexagonal with 1D, 2D or 3D clusters located in the sites of lattice. The dust particles forming 2D or 3D cluster, in turn, were in the ordered state. The transition from 2D to 3D clusters was observed at the increase of gas pressure. In the region 2 the destruction of crystals consisting of 3D clusters and the destruction of ordered 3D clusters into individual threadlike (1D) clusters was observed. In the region 3 the dense disordered structures consisting from threadlike clusters were observed. It was found that the regions of existence of structured clusters and the regions of structural transitions, were characterized by the higher values of the reduced longitudinal electric field strength than the regions of destruction of ordered structures.
[Show abstract] [Hide abstract] ABSTRACT: form is given. This work considers the dynamics of long filamentary pulse discharge generated along the contact zone of two co-flown gases , basically: hydrocarbon fuel and oxidizer. The effect of the mixing actuation in compressible flow is observed because of the gas
dynamic instability arisen after the discharge generation. The mixing efficiency is examined qualitatively by means of Probe Discharge Breakdown Spectroscopy. An adequate measurement of the mixing efficiency is principally important for this study. The best way for that is to know the concentrations of main components and their spatial distribution. The idea is to realize breakdown of the so-called “probe” discharge that has much less power than the main one at some delay after the main breakdown and to analyze the spectrum of this probe discharge. The temporal resolution of this method is equal to the duration of probe discharge luminescence -
[Show abstract] [Hide abstract] ABSTRACT: form only given. Over the variety of available sensors dedicated to electric (E)-field characterization, the use of antennas constitutes the most widespread technique. While such probes are convenient and provide a good sensitivity, they remain invasive and bandwidth limited. At the opposite, fibered electro-optic transducers1 are fully dielectric, millimeter sized and allow to perform measurements of the E-field vector from DC to several gigahertz and even up to terahertz frequencies using equivalent-time sampling. Furthermore, recent developments lead to a simultaneous characterization of 2 transverse E-field vector components with a single EO probe2. Based on polarization state modulation, the EO transducer is linked to a remote (up to 30 meters) optoelectronic set-up including a ultra low noise laser feeding the probe and a real time optical set-up to manage the modulation treatment. The automated and servo controlled measurement bench is temperature dependent free. The available measurement dynamics exceeds 100 dB, ranging from less than 1 V. m-1. Hz-1/2 up to the breakdown electric field in air.An exhaustive comparison between BO sensors and other technologies will be firstly given during the conference. This analysis will be based on intrinsic sensor properties, such as sensitivity, frequency bandwidth, vectorial selectivity, spatial resolution and induced perturbation on the field to be measured. After recalling the principles of the BO effect, the optical arrangement of the optical probes will be described. The characterization of the BO system will be presented together with experimental results illustrating the potentialities of BO sensors. Among these examples, measurements of pulsed B-field in air (pulsed power), water (specific absorption rate evaluation in pulsed regime) or in plasma (real time evolution of the electrical discharge associated B-field) will be shown.
[Show abstract] [Hide abstract] ABSTRACT: form only given. NOx and associated acids are investigated with regards to their role for biomedical application. NOx are produced by two different plasma sources, a RF kINPen and a μS Plasma gun, both are cold atmospheric pressure plasma jets. The first one is powered by a radio frequency voltage [1, 2] of 1 MHz, the second one is a dielectric barrier discharge powered by a μs pulse voltage [3, 4]. For these two sources, NOx are produced by many complex chemicals reactions occurring in the interaction of the active plume with surrounding air. With the mid infrared quantum cascade laser absorption spectroscopy , we are able to measure the absolute density of NO2 and O3 produced by both plasma sources. Correlating the measurements in situ with optical emission spectroscopy, great differences in the excitation processes of fundamental species such as O, N2, OH, N2 and N2+ can be observed. With a parametrical study, varying the voltage and the pulse repetition frequency, we are able to modulate the NO2 densities production from a few tens to a few hundreds of ppb. Such parametric analysis also shows that large variations in the population of the different molecular bands of the NO gamma system, are associated with the plasma gun operation regime. These physical parameters play a major role in the NOx production and yield vital clues to discriminate major kinetic reactions involved in the NO production and in relation with future numerical simulations.
[Show abstract] [Hide abstract] ABSTRACT: Literature indicates that introduction of Nano fillers into PP films will improve its electrical characteristics, such as the PD resistance, breakdown strength and loss factor . Some dielectric properties of Nano filled polymers have shown remarkable improvements such as permittivity and space charge accumulation . This research work investigates the effect of Nano fillers content on the PD resistance and Breakdown strength of the polypropylene films with 0%, 2% and 6% organoclay Nano fillers when the samples are subjected to Surface Discharges. The degree of erosion is quantified through microscopic and surface profilometer measurements that will help to figure out the resistance of the sample to surface discharges.
[Show abstract] [Hide abstract] ABSTRACT: Non-thermal intense pulsed electric field (PEF) can be a novel physical stress onto organisms. A large number of experiments on inactivating or killing microorganisms by using PEFs have been reported since Sale and Hamilton's experiment in 1960's. Strong fields exceeding 10 kV/cm are likely to damage cell membrane of microorganisms, and their repetitive application leads to the death. Inversely, there have been several studies on activating organisms by the electrical pulses, such as accelerating germination and growth rate , enhancement of proliferation on mammalian cells .
[Show abstract] [Hide abstract] ABSTRACT: Atmospheric pressure plasmas have been developed in the last decades for many material treatment applications such as cleaning and activation of surfaces, interaction with in-vivo and in vitro tissues and, as such, they play an increasing role in disinfection and sterilization of surfaces. Heat sensitive polymers can be plasma treated with the final aim of microbial inactivation: given for granted such a capability for many different atmospheric pressure plasma sources, in this work, we focus on the investigation of the effectiveness of the treatment of a polyethylene (PE) polymer foil commonly used for pharmaceutical packaging by means of a Dielectric Barrier Discharge (DBD) operated on a “large area” at atmospheric pressure in ambient air. For effectiveness of the treatment we considered the uniformity of the variation of water contact angle (WC) induced by the plasma on different positions of the treated area (for example, 160×300 mm) and the capability not to affect negatively the properties of the plasma treated packaging material in terms of weldability (for example, hot plate weldability). The surface of the polymer foil has been characterized by measuring the variation of water contact angle (WCA) in different position on the treated sample; Attenuated Total Reflectance-Fourier Transform Infrared spectroscopy (ATR-FTIR) has been used to investigate the surface oxidation of the treated samples; moreover, polymer weldability after plasma treatment has been tested on a packaging machine that includes a contact hot plate. This procedure allowed correlating surface oxidation with polymer weldability and with plasma treatment parameters. Results show that it is possibile to select geometrical (DBD gap width; for example, 2mm) and generator operating conditions (for example, 12kV, 100Hz) suitable to obtain uniform change in WCA (for example from 98.2° to 55°) while maintaining good weldability for the treated material. Aging- of the treated polymer for what concerns WCA has also been considered, together with treatment time compatible with the final industrial on-line treatment, forming and welding process.
[Show abstract] [Hide abstract] ABSTRACT: form only given. Discontinuous Galerkin finite element methods (DG-FEM) are a powerful solution technique for nonlinear hyperbolic conservation laws, such as those that arise in the modeling of plasma. DG-FEM can be applied to achieve high-order spatial accuracy; however, one drawback of classical DG-FEM with explicit time-stepping is their poor CFL restriction compared to high-order finite difference or finite volume counterparts. In kinetic models of collisionless plasma, i.e. kinetic Vlasov models, this small time step problem is further exacerbated due to the possibility that some particles in the system may travel at moderate to large velocities. In this work, we extend our single dimension, 1D-1V semi-Lagrangian discontinuous Galerkin (SLDG) method1 to 2D-2V, two dimensions for configuration space, and two dimensions for velocity space. The DG representation allows us to capture complicated geometries in configuration space through the use of unstructured grids. Our method uses operator splitting techniques that enable us to apply different time stepping options in each direction. For velocity space, we use the semi-Lagrangian DG method on a structured grid that removes CFL limitations on the electric field. For configuration space, we apply explicit Runge-Kutta time stepping on unstructured grids. In order to mitigate restrictive CFL conditions, each sub-problem is sub-cycled according to a local velocity. Due to the fact that the proposed scheme is mesh-based and high-order accurate, we can compute solutions with much less statistical noise than what is found in traditional particle-in-cell (PIC) solutions of comparable resolution. We present simulation results for the formation of a plasma sheath in a collisionless plasma. We start with a 1D problem, and then demonstrate how the multi-D extension performs on a radially symmetric cylinder. We argue that our high-order mesh based method allows us to simultaneously produce accurate results - or the plasma sheath near the wall as well as the quasi-neutral region.
[Show abstract] [Hide abstract] ABSTRACT: form only given. Pulsed, nanosecond discharges (PNDs) are notable for their large volumes and nonthermal nature. The large volume is attractive for material processing and the nonthermal electron can be used to drive reactions with minimal gas or substrate heating. However, the stochasticity of such plasmas presents a challenge for simulations, while the short time scales and large fields limit experimental diagnostics. This has led to a degree of uncertainty in the electron energetics of PNDs, particularly when nonlocal electron effects become important. This uncertainty also inhibits the predictive capabilities for PNDs. This work examines the population kinetics of a helium PND, and uses them to infer conclusions about the electron energetics. Specifically, the absolute triplet metastable densities are measured with laser-absorption spectroscopy. These densities are used in combination with a global model of a helium plasma to predict plasma emissions. These emissions are compared with the measured plasma emissions. As this method assumes electron locality, the degree of agreement between the two should reflect the accuracy of this assumption. The results are discussed in the context of the electron energetics, and compared to preliminary results of PIC-MCC simulations.
[Show abstract] [Hide abstract] ABSTRACT: form only given. Pulsed inductive plasma devices such as the common theta-pinch have become a standard high energy plasma source in research and industry. Recent pulsed inductive plasmas currently being investigated by the fusion and space propulsion communities utilize deuterium and xenon, respectively, and have provided promising new results. However, little has been done to better understand the energy conversion processes during early plasma formation times (i.e., during the initial inductive coupling). The broad efforts of this research are to elucidate the electric-to-particle energy conversion processes during initial plasma formation over time scales of 10-8 to 10-6 seconds. In this work an analysis of spectral emission data is performed on a theta pinch test article intended for use in field reversed configuration (FRC) studies. Testing is performed on a pulsed xenon plasma at energies of around 80 joules, neutral back-fill pressures of 10-2 Torr, and an RLC discharge frequency of 500 kHz. Efforts are paralleled by magnetic field studies (B-dot probes, flux loops) of the same experiment. Using a collisional-radiative model previously developed for analysis on xenon Hall effect thrusters, line emission intensity ratios are used to approximate electron temperatures independent of plasma density. A Princeton Instruments SP2300i spectrometer with PI-MAX 1024×1024 pixel iCCD camera is used with gate times of 10-9 to 10-8 seconds and variable delay to allow for time-resolved spectral data.
[Show abstract] [Hide abstract] ABSTRACT: form only given. The MTF of the three stages configuration, which is on the way at LANL and Air Force in America, is harassed due to energy loss and instability from long distance transportation, while the MAGO of two stages configuration, which is improving from its old version at All-RRIEP in Russia, is facing the serious impurity washed due to plasma passing the narrow nozzle between two stages. We are proposing one stage of configuration for fusion ignition of magnetized plasma driven by proper pulsed power source. Comparing to two or three stages mentioned above, this configuration can reduce energy loss lower the damage from impurity and ease the instability due to its integrated simple geometry. The two dimensional magneto-hydrodynamic code is developed to simulate the forming process of reversed field configuration target (FRC) in this one stage of configuration. The simulating results show that the proper temperature magnetic field and plasma density can be achieved for further imploding compression, which can get several hundred electron voltage by initial 1-2 electron voltages several Tesla by initial 0.2-0.4 seed field and ten to the seventeenth or eighteenth per centimeters density by initial ten to the fifteenth or sixteenth per centimeters, individually. Based on these simulating results, a device to create the FRC target is proposed and building in China, which is supposed to be finished in next couple of years. Meanwhile, we develop one dimensional radiation magneto-hydrodynamic method for the cylindrical geometry to investigate the process of ignition. The concept of the new mechanism of ignition called the local center ignition (LCI), which is believed from the embedded strong magnetic field is proposed. The analyzing and simulating results from LCI model show that : 1) the embedded magnetic field may play a key important role on the process of ignition, 2) the shaped pulse power including the initial pulse height the pulse width and puls- rising time can affect the process of ignition, and 3) the condition of ignition with the embedded magnetic field is derived and analyzed by means of the simple analytic model and one dimensional model individually, both of them show in agreement with each other, which means that the ignition with one stage configuration in magnetized plasma can be achieved with proper conditions.The simulating results show that the proper temperature. magnetic field and plasma density can be achieved for further imploding compression, which can get several hundred electron voltage by initial 1-2 electron voltages.several Tesla by initial 0.2-0.4 seed field and ten to the seventeenth or eighteenth per centimeters density by initial ten to the fifteenth or sixteenth per centimeters, individually .
