    In an electrical circuit with plasma generation, the resistance and reactance components on the circuit cause a phase difference between the applied voltage and the power supplied current. The resistance and reactance components are determined by the dielectric, working gas, and plasma that make up the circuit. While each component of the dielectric and working gas is constant, the plasma component varies depending on its properties. As a result, the resonant frequency in the circuit varies depending on the plasma properties. In a configuration where plasma is emitted from a quartz tube and irradiated onto a copper disk, the reactance component is inductive when the plasma is generated in a single shot. When the intensity of the dynamic electric field generated by the plasma charging on the copper disk exceeds the intensity of the dynamic electric field formed by the power supplied electrode, the reactance component is capacitive because the plasma reciprocates between the electrode and the copper disk.

    <jats:p>For the plasma generated as a stationary wave in a vacuum vessel, the propagation velocity of the plasma was derived by a simple composite analysis consisting of a plasma emission image and a time fluctuation of the plasma current. The propagation wavelength of the plasma was derived from the shading interval length of the plasma emission intensity obtained by the digital camera in the visual analysis, and the propagation frequency of the plasma was derived from the time variation of the plasma current measured by a current probe in the electrical analysis. © 2022 Institute of Electrical Engineers of Japan.

    Two-dimensional (2D) turbulence measurement by using microwave imaging reflectometry (MIR) has been performed in the reversed field pinch (RFP) plasma in TPE-RX. In this work, the maximum entropy method (MEM) is used to estimate the 2D k-spectrum. The turbulences between the pulsed poloidal current drive (PPCD) and the high Θ plasmas are studied. The m = 1 modes are dominant in PPCD plasma, while in high Θ plasma the k spectrum expands to the high k range and the turbulence propagates in the electron drift direction. The preliminary result shows that PPCD plasma switches off the turbulence, and the high Θ plasma has strong turbulence.

    A high poloidal beta, β<sub>p</sub>, was achieved using pulsed poloidal current drive (PPCD) in a toroidal pinch experiment-RX (TPE-RX). The plasma electron density and temperature increased, hence improving β<sub>p</sub> from 5 to 30% during PPCD. β<sub>p</sub> is almost equal to the total beta in the reversed-field pinch (RFP). D-alpha emission from recycling deuterium by the plasma-wall interaction decreased during the PPCD. An improved particle confinement time was indicated by a ten fold increase in the ratio of the total number of particles to the D-alpha emission. Single pellet injection into the good particle confinement plasma, achieved by the PPCD, produced high density plasma with high beta values. The plasma electron density rapidly increased to triple that of standard plasma, and high density was maintained till the end of the PPCD period. The electron temperature was lower than that of PPCD without ice pellet injection, but β<sub>p</sub> remained almost the same because the plasma electron density was higher with pellet injection.

    We have measured fast magnetic fluctuations (> 10 kHz) using a complex edge probe in the edge region of TPE-RX reversed-field pinch plasma. We observed that the frequency of magnetic fluctuation at the peak power in the frequency spectrum varies with time, and this frequency variation is determined by the values of pinch and reversed parameters, although the amplitude of the fast magnetic fluctuations are almost independent of those parameter values.

    Microwave imaging reflectometry (MIR) was developed in TPE-RX, one of the world's largest reversed field pinch (RFP) devices. The system optics are made of aluminum mirrors, Teflon lenses, and Plexiglas plates in order to reduce size. In this system, frequencies are stabilized so that noise can be reduced using narrow bandpass filters. A 4×4 2-D mixer array and phase detection system have also been developed. With this system, density fluctuations in the high-Θ RFP plasma, pulsed poloidal current drive (PPCD) plasma, and quasi-single helicity (QSH) plasma are observed in TPE-RX. This is the first MIR experiment in an RFP device.

    A very high beta value was obtained during pulsed poloidal current drive (PPCD) operation in a reversed-field pinch (RFP) plasma during a TPE-RX experiment. Poloidal beta is almost equal to total beta in the RFP, and is as high as 30% near the end of PPCD operation. During the PPCD operation, the magnetic fluctuation associated with the dynamo effect is reduced, and improved confinement is realized, which results in this high beta value.

    The energy distribution of neutral particles emitted from STP-3(M) reversed field pinch (RFP) plasma has been investigated by a neutral particle analyzer (NPA) using a two-channel energy detector with the time resolution of 0.5μs over the whole duration of the discharge. NPA data show a high energy tail as well as the bulk ion distribution. It is found that the ion temperatures of bulk and high energy tail component have reached to the maximum before reversed magnetic field configuration, and that the tail temperature increases in the quiet period (QP). Furthermore, we found that the high energy ion density increases in both the relaxation period and the QP. The ion energy confinement time evaluated from magnetic reconnection model and the obtained ion energy spectrum is found to be about 720μs much longer than the electron energy confinement time 60-100μs, when ion heating mechanisms are discussed.

    In this study, the novel analysis method for electron and ion temperature was investigated by experiment in non-thermal equilibrium plasma. Since the masses of the electrons and ions in plasma are different, the electron temperature is different from the ion temperature with non-thermal equilibrium state. Utilizing the fact that the electron and ion temperatures are different, a method to analytically derive the electron and ion temperatures was investigated. The measured time average temperature is linearly proportional to the frequency of plasma generation. The slope of the line indicates the difference between the electron and ion temperatures, and the intercept indicates the ion temperature. From the experimental results, it was shown that the electron and ion temperatures of non-thermal equilibrium plasma can be derived, and the validity of the measurement was confirmed by comparison with other measurement.

    A new method to determine the arbitrary electron energy distribution function (EEDF) from the optical emission spectroscopic measurement in atmospheric-pressure plasma is introduced. The optical emission spectroscopy (OES) continuum emission spectrum, dominated by electron-neutral bremsstrahlung radiation, is analyzed to inspect the usefulness of the conventional OES measurement range for EEDF determination. The EEDF is reconstructed from the OES continuum radiation spectrum by applying machine learning to solve the bremsstrahlung emissivity equation inversely. Through iterative statistical analysis, the presented genetic algorithm can locate the EEDF reliably. Preliminary experimental EEDF results of an argon dielectric barrier discharge (DBD) OES measurement are given. The electron energy range and resolution of the determined EEDF are discussed. The results showed potential for accurate determination of the arbitrary EEDF in atmospheric-pressure plasma using simple OES equipment.

    We found that the low temperature plasma (LTP) treatment with the helium plasma jet could induce protein aggregation, and turned erythrocytes to be a source for clot via hemolysis. As an essential point in our system is that the clot formation is extended to red blood cells and serum proteins, we proposed whole blood clots formation as a new process linked with LTP treatment.
    At the end of this project, we feel that suitable equipment-independent parameters are we still needed to understand the observed effects and be clear the concept of hemostasis by LTP treatment. Nevertheless, we successfully reached to propose a new concept that LTP treatment is a tissue processing technology keeping homeostatic balance as analogous application as semiconductor fabrication, from the viewpoint of applied physics and pathology.

  • Study on Broadband Pulsed Surface Wave Oscillator with Double-Corrugation

    Broadband pulsed surface wave oscillators with slow-wave structure composed of double-corrugation are examined. The dispersion characteristics of surface wave can be controlled by the corrugation parameters. The surface waves in the range from 20GHz to 40GHz are examined numerically and experimentally. Weakly relativistic electron beams are generated by a disk type cold cathode, not by a hot cathode. By injecting the beam into the double-corrugation, an intense surface wave excitation and a frequency tunability of about 20 percent are demonstrated based on the double-corrugation. And high frequency operation based on the higher order modes of double-corrugation are examined numerically and relatively strong radiations of higher order mode are demonstrated experimentally. Moreover, the intense surface wave excitation is extended up to 170GHz-band. The higher order and extended surface wave operations are of considerable interest for an intense broadband terahertz wave source.
