    A new algorithm to analyze Langmuir probe (LP) data has been developed with Daubechies (DWT) and bi-orthogonal wavelet transforms (BWT), which remove the noise from the raw data without losing important information. The first derivative of the LP signal is processed using BWT and its result readily provides the peak value, which corresponds to the plasma potential. The LP data processed using DWT provides the saturation current lines directly, which corresponds to the electron and ion saturation currents. The region required to obtain the electron temperature can be automatically determined from the plasma potential to the end of the ion saturation current line so that the input from the analyzer is not required to continue the analysis. The plasma density can be obtained from the electron saturation current and the electron temperature. Accuracy tests of the algorithm are carried out with simulation probe data containing various levels of random noise. The results show that the algorithm based on the wavelet transforms removes noise effectively and that the plasma parameters are obtained accurately. View full abstract»

    Energetic electrons trapped in the radiation belts undergo bounce motion about the geomagnetic equator. The behaviors of the trajectories of these electrons interacting with a large amplitude whistler wave are explored, with the electron energy and wave amplitude as variable parameters. A surface of section technique is used to examine the chaoticity of the system graphically. The wave amplitude required causing an electron trajectory to become chaotic decreases with increasing electron energy. Once the trajectory of an electron becomes chaotic, it can wander into the loss cone and subsequently precipitates into the ionosphere and/or the upper atmosphere. This chaotic scattering process requires a threshold field for the commencement of chaotic behavior in the electron trajectories. Therefore, a loss-cone negative mass instability process to amplify whistler waves by electrons in the bulk of the energy distribution is also studied. The numerical results show that the injected whistler waves can be amplified by more than 20 dB, agreeing with the experimental results. This amplification process reduces considerably the required field intensity of injected whistler wave for the purpose of precipitating those tail electrons in the megaelectronvolt range.

    New arguments supporting the supposition that the ozone is transported along a corona discharge radical shower (CDRS) reactor by the electrohydrodynamic (EHD) flow are presented. The arguments are based on the analysis of the corona discharge, which is a precursor of the EHD flow in the CDRS reactor, and on the measurements of velocity field of the EHD flow in the CDRS reactor by the particle image velocimetry (PIV). The obtained velocity flow structures and the possible causes of the ozone transport in the CDRS, i.e., diffusion, additional gas flow, EHD flow, and convection by the main flow, were discussed basing on the conservation equations for the EHD flow. The discussion showed that the EHD flow plays a dominant role in the ozone transport. This is also supported by the results of a simple phenomenological model for one-dimensional description of EHD-induced ozone transport in the CDRS reactor. The results of the computer simulation based on this model explained the main features of the measured ozone distribution in the CDRS reactor, establishing the EHD flow as the main cause of the ozone transport from the discharge region upstream, i.e., against the main flow.

    A new method of plasma production at atmospheric pressure, capacity-coupled multidischarge (CCMD), is proposed. The discharge gaps in the CCMD consist of a common electrode and a number of compact electrodes (CCE) which are directly coupled with small capacitors for quenching the discharge. A simple CCE structure is provided by a cylindrical capacitor, the inner conductor of which is used as a gap electrode. A short pulse discharge is observed to appear homogeneously at each CCE. A charge transfer for the single pulsed discharge is 10-100 times as large as that of the conventional dielectric barrier discharge. In the CCMD using O2 gas, a high efficiency of ozone production has been obtained. A device configuration of the CCMD is quite flexible with respect to its geometrical shape and size. The CCMD could be used to produce plasmas for various kinds of industrial applications at atmospheric pressure. View full abstract»

    An efficient grid-free numerical method is developed for particle simulations in plasma dynamics. The method relies on a treecode algorithm to solve the Poisson equation for interacting charged particles. Such algorithms have been extensively used in astrophysics, fluid dynamics, and molecular dynamics, and our aim is to assess their capability in plasma dynamics in comparison with traditional mesh-based methods such as particle-in-cell (PIC). It is well-known that PIC simulations have difficulty resolving local particle interactions within a grid cell, and we expect the grid-free treecode algorithm to have an advantage for problems involving small-scale features and highly nonuniform particle distributions. To illustrate this point we apply direct summation, treecode, and PIC methods to simulate a virtual cathode in one dimension. The treecode and PIC methods are found to be much faster than direct summation, but the treecode yields the correct solution while spurious features are present in the PIC results. The present work treats a one-dimensional problem, but the treecode algorithm generalizes directly to higher dimensions. View full abstract»

    As the scale of semiconductors shrinks and the interconnect layer develops to tens level, the resistance-capacitance ( RC) delay of signals through interconnection materials becomes a big obstacle for high-speed operation of integrated circuits. In order to reduce the RC delay, low-k materials will be used for intermetal dielectric (IMD) materials. As a result, new etching conditions must be developed to match the material properties. We present the modeling results of a two-frequency capacitively coupled plasma (2f-CCP) with N2-H2 gas mixture, which is known as a promising one for organic low-k materials etching. We have developed a self-consistent simulation tool which includes neutral-species transport model, based on the relaxation continuum (RCT) model. Not only the plasma transport and spatial distribution, but also those of neutrals are important issues for the etching process. For the etching of low-k materials by N2-H2 plasma, N and H atoms have a big influence on the materials. Moreover, the distributions of excited neutral species influence the plasma density and profile. Therefore, we include the neutral transport model as well as plasma one in the calculation. The plasma and neutrals are calculated self-consistently by iterating the simulation of both species until a spatiotemporal steady-state profile could be obtained. In the simulation of neutral species, the interactions of excited states and vibrational levels of both N2 and H2 molecules are considered too. The profiles of periodic steady-state plasma and neutrals species in the 2f-CCP system is discussed. View full abstract»

    This paper proposes a methodology reducing the number of RF cycles necessary to reach time periodic steady-state solutions for efficient simulations of a three-moment plasma model. Our methodology employs a feedback control approach in conjunction with an implicit time integration scheme. Feedback gains are rigorously estimated by taking into account plasma responses during simulation. Through the one-dimensional simulation of a parallel plate capacitively coupled RF argon plasma, the proposed feedback control approach demonstrates its capability to dramatically reduce the number of RF cycles required to reach the time periodic steady state, resulting in several factors of speedup in simulation time. The simulation result showed that electrons emitted in a temporary cathodic sheath could acquire supersonic velocities and shocks could form near the corresponding sheath boundary as they enter a bulk plasma region.

    Formation of carbon particles due to plasma surface interaction has been studied using an electron cyclotron resonance (ECR) plasma device. The interaction produces two sizes of groups: small spherical ones of 2-25 nm in size and large particles of irregular shape and above 100 nm in size. The latter are considered to be flakes peeled from carbon films deposited on the reactor wall. The total amount and average size of small particles tends to decrease with increasing the sheath voltage Vs between plasma and the carbon fiber composite (CFC) wall from 14 to 214 V. Optical emission intensities of CH and C as well as gas absorption rate to the CFC wall also decrease with increasing Vs. These results suggest that the carbon-containing species emitted from the CFC wall contribute to formation of small particles. View full abstract»

    A simple derivation of the new scaling of Child-Langmuir law in the quantum regime is presented. Based on a dimensional argument of the Schrodinger equation and the Poisson equation, the limiting current in the deeply quantum regime is found to be proportional to the square root of the gap voltage and to the inverse fourth power of gap spacing. The importance of electron exchange-correlation interactions in the quantum regime is discussed. View full abstract»

    The feasibility of manufacturing a 2-MW CW coaxial cavity gyrotron at 170 GHz has been demonstrated and data required for fabrication of an industrial tube have been obtained. An engineering design of a prototype started recently with the goal to provide gyrotrons with 2-MW microwave output power for International Thermonuclear Experimental Reactor (ITER). The design of critical components of the prototype tube as electron gun, cavity and RF output system will be verified under realistic conditions at short pulses using the experimental coaxial gyrotron at Forschungszentrum Karlsruhe.

    This paper describes experimental and theoretical studies of nonstationary processes in a relativistic X-band gyrotron with delayed feedback. For the first time, the chaotic self-modulation regimes were realized with the power level exceeding 2 MW and efficiency up to 17%. The full particle-in-cell simulations of the self-modulation regimes have been carried out. The period-doubling pattern of the transition from the periodic to chaotic self-modulation regimes have been observed both in experiment and simulations. View full abstract»

    The disturbance resulting from the presence of a positively biased Langmuir probe at an equilibrium steady-state ion sheath boundary in the drifting plasma is simulated by the two-dimensional particle-in-cell (PIC) method in rectangular coordinates. The positive potential of the probe was found to shield electrons on the side of the probe away from the sample surface from the negative potential of the sample surface and thereby cause an increase in the electron current drawn by the probe. The drifting ions on the same side of the probe are slowed by it and thereby raising the ion density in front of the probe. The electron currents of the probe are calculated at different probe positions from the sample surface. It is found that the sheath boundary as defined by the probe current is wider than the unperturbed boundary. The widening of the sheath boundary agrees well with experimental sheath boundary measurements. View full abstract»

  • Emittance growth of high-energy electrons produced from the laser wakefield acceleration

    When a laser wake field passes a sharp downward plasma density transition, a significant amount of plasma electrons are trapped and accelerated to relativistic high energies over a distance of the plasma wavelength. Phase space area of the plasma electrons remains constant during acceleration in the ion channel, but it was found that the phase space area, which is related with emittance, increases rapidly by the nonlinear space-charge field when the electron beam moves out of the plasma. As a result, the emittance of the accelerated electron beam grows severely during propagation in free space, and ultimately this limits the beam intensity. The emittance growth problem is investigated with two-dimensional particle-in-cell simulations, and several methods are suggested to suppress such a rapid emittance growth. View full abstract»

    The effect of ion mass and charge state on plasma transport through a 90°-curved magnetic filter is experimentally investigated using a pulsed cathodic arc source. Graphite, copper, and tungsten were selected as test materials. The filter was a bent copper coil biased via the voltage drop across a low-ohm, "self-bias" resistor. Ion transport is accomplished via a guiding electric field, whose potential forms a "trough" shaped by the magnetic guiding field of the filter coil. Evaluation was done by measuring the filtered ion current and determination of the particle system coefficient, which can be defined as the ratio of filtered ion current, divided by the mean ion charge state, to the arc current. It was found that the ion current and particle system coefficient decreased as the mass-to-charge ratio of ions increased. This result can be qualitatively interpreted by a very simple model of ion transport that is based on compensation of the centrifugal force by the electric force associated with the guiding potential trough.

    A stability analysis of a propagating ion beam through a plasma medium is carried out in terms of transverse conductivity of the background plasma. Coupled eigenvalue equations are obtained for the flat-top density profiles of beam ions and plasma electrons. The dispersion relation of the transverse instability in an intense ion beam propagating through the background plasma is derived, including the plasma conductivity (4πσ/ω), the magnetic decay time τd and fractional charge neutralization f. It is shown that the obtained dispersion relation recovers the previous one of the electron-ion two-stream instability in the limit of σ→0. On the other hand, the dispersion relation of the resistive-hose instability is recovered when σ→∞. Influence of the finite transverse conductivity σ on the resistive hose stability properties are investigated for the ion beam propagating through a plasma channel. The growth rate of the resistive hose instability decreases considerably as the transverse conductivity 4πσ/ω decreases from infinity. View full abstract»

    The 3.3-kJ dense plasma focus (DPF) device is used to deposit diamond-like carbon thin films by ablating the high purity graphite fitted to the top of the anode. The plasma focus dynamics was observed using shadowgraphic method to confirm the symmetrical current sheath dynamics and to outline the thin-film deposition process in DPF device. Shadowgraphic results showed that the profile of current sheath remains symmetrical in axial as well as radial collapse phase even for the graphite fitted anode. The ablation of the graphite top was found to start about 50-70 ns after the first peak on voltage probe signal and continued for more that 1 μs. The deposited films have been analyzed for their structure, composition and bonding characteristics. The effect of number of DPF shots and angular position of the substrate on Raman spectra of deposited films was analyzed in terms of Raman peak intensities and positions. The surface composition of the deposited films was obtained using X-ray photoelectron spectroscopy and is explained on the basis of film deposited conditions and ion emission characteristics of the plasma focus device.

    As semiconductor devices continue to shrink in size, demands for the formation of ultra-shallow junctions (USJ) are increasing. Pulsed plasma doping (P2LAD) has emerged as a scaleable and cost effective solution to dopant delivery, since it is capable of high dose rates at ultra-low energies (0.02-20 kV). In P2LAD, a pulsed plasma is generated adjacent to the silicon wafer using pulsed biases. Typical pulse widths range between 5 and 50 μs, and pulse repetition rates are between 100 and 10000 Hz. Time-resolved Langmuir probe measurements showed that cold plasma is present during the afterglow period, which may play an important role in process control. Probe measurements also showed the presence of primary electron and electron beams during the initial pulse-on stage in both Ar and BF3 plasmas. Ion mass and energy analysis indicated that BF2+ is the dominant ion species in the BF3 plasmas, with BF+ as the second-most abundant ion species. View full abstract»

    The paper is concerned with numerical modeling of an electric arc in the plasma torch with combined stabilization of arc by gas and water vortex. The axisymmetric model includes the arc discharge area between the outlet nozzle for argon and the outlet nozzle of the hybrid plasma torch. It is proved that the addition of argon increases the plasma velocity but does not influence substantially the plasma temperature. The outlet velocities exhibit the maximum difference up to 3000 ms-1 for 500 A, regarding a water-stabilized plasma torch. Transition to supersonic flow in the axial discharge region near the outlet occurs as a result of higher velocity and lower temperature for 500 A. The calculated velocities, temperature, and electron concentration profiles exhibit good agreement with experiments. View full abstract»

    The geometrical effects of an anode nozzle in a nontransferred plasma torch on air entrainment are examined by measurements of plasma composition using a quadruple mass spectrometry. In addition, the radial and axial distributions of plasma enthalpy, temperature, and velocity are measured by using an enthalpy probe method. Two types of anode nozzle geometry, i.e., cylindrical and stepped nozzles, are employed for the torch in this experiment. As a result of gas composition measurements, the new stepped nozzle turns out to produce a thermal plasma jet having lower air content in it compared with the conventional cylindrical nozzle. The plasma jet produced by the stepped nozzle exhibits higher enthalpy and temperature, especially around the core of the plasma flame, due to less intrusion of ambient air. Furthermore, the axial velocity distribution with a slowly changing variation is observed in the stepped nozzle case because of the plasma flow less disturbed by air entrainment. From these experimental results of thermal plasma characteristics and nozzle geometry effects on air entrainment, a high quality of coating products are expected in plasma spraying by using the stepped nozzle due to higher plasma enthalpy and temperature and lower velocity drop along the plasma jet.

    A three-dimensional (3-D) transient numerical model has been developed to investigate the arc root rotation driven by an external magnetic field and its influences on the thermal plasma characteristics in the nontransferred plasma torches with rod-type cathode (RTC) and well-type cathode (WTC). The 3-D distributions of electric current density are obtained from a current continuity equation along with the generalized Ohm's law, while the magnetic fields induced by the arc, superimposed on the external field, are calculated by a magnetic vector potential equation. The coupled interactions between the arc and the plasma flow are described in the framework of time-dependent magnetohydrodynamic (MHD) equations in conjunction with a K-ε turbulence model. Numerical simulations have been focused on finding the magnetically driven rotating velocities of the anode arc root for the RTC torch and the cathode arc root for the WTC torch, respectively. The external application of magnetic field turns out to be a practical method for rotating the arc root rapidly to reduce the electrode erosion in the typical torch operation. The 3-D simulations also reveal that a large swirling motion is induced by the external magnetic field, thereby the distribution of plasma temperature is helically distorted. In addition, it is shown for the RTC torch that the rotation velocity of arc root rises in proportion to the square root of external field strength and that it increases with input current but decreases with gas flow rate.

    The firing and sustaining characteristics in an AC microdischarge cell with three electrodes are examined based on varying the distances between the three electrodes. In particular, the breakdown voltage and the sustaining voltage are measured as a parameter of the width of the discharge gap between the three electrodes. It is found that the firing and sustaining conditions vary according to the distance between the three electrodes and the discharge characteristics strongly depend on the voltage applied on the three electrode, especially with a wide discharge gap structure.

    This paper describes the experimental study of indoor air control by the plasma catalytic hybrid system. The basic characteristics of the ammonia and toluene decomposition were investigated as a model of the deodorizing process. It was found that the application of plasma discharge without catalyst can be dangerous for humans due to the ozone and carbon monoxide (CO) formation. The catalyst, which was applied to the plasma unit, decreases the ozone concentration more than ten times and the CO amount up to five times. Catalyst decreases a little bit the ions generated by the discharge but the catalyst application in the plasma treatment was recognized as necessary. The plasma catalytic hybrid system can be a promising method of the indoor air ionization and deodorization. View full abstract»
