Lightning can cause severe damage to aircraft, lightning direct effect test is very important for research of spacecraft material, design of structure of aircraft, but the limitation of the measuring technology and special test apparatus has become the technical bottleneck. Lightning current components for lightning direct effect test consist of component A (initial strode), component B (Intermediate current), component C (Continuing current) and component D (Restrike). Lightning current components A and D can be produced by the type of RLC circuit and crowbar circuit. The efficiency of the conventional RLC circuit in generating long duration time impulse current wave is relative low. To solve this problem, a replaceable electrodes triggered vacuum switch is designed and researched and then a high efficiency crowbar circuit which produces lightning current component A is designed in this paper.

In this paper, the effects of nanosecond pulsed electromagnetic field (NPEMF) on mitochondrial membrane potential were studied. The pulsed electromagnetic field was induced by a pulsed square wave with adjustable frequency of 0∼100Hz. The rise time was less than 10ns and the duration time was 100ns. The testing amplitude of NPEMF was from 0.10mT to 1.30mT, and the frequency was 5Hz, 10 Hz, 30 Hz, 50Hz respectively. It was applied on human prostate cancer cells (PC3) under 23 °C experiment temperature and 2 hours exposed time. When the frequency was 30Hz, the experimental results showed the mitochondrial membrane potential value decreased after irradiation compared to the control group. However the relationship between mitochondrial membrane potential and NPEMF is nonlinear. T he potential was smallest when the amplitude of NPEMF was 0.44mT. When the amplitude of NPEMF is constant, the mitochondrial membrane potential increased with the increase of frequency. The value of exposed group was larger than control group 2(23 C, no irradiation). It showed that the electromagnetic field could reduce the damage caused by low temperature.

Summary form only given. Over the past years cold atmospheric pressure plasma jets (CAPPJ) have received considerable attention due to their unique capabilities and considerable application potentials in various industrial and scientific applications. It has been demonstrated by several research groups that CAPPJs are not continuous jets but discrete fast-moving plasma bullets with supersonic velocities in the order of104–105m/s. However, possible mechanisms responsible for the creation and propagation of plasma bullets still remain essentially open. Presently two explanations for this phenomenon exist. One is the ionization wave model, and the other is the streamer-like model based on photo-ionization.

Summary form only given. The propagation of plasma bullet in a plasma jet is described under the base of fluid theory of plasma diffusion and plasma drift as well as the gas flow. The origin of plasma bullet is analyzed to be the electrostatic plasma diffusion wave propagating in the plasma column of plasma jets. The plasma diffusion waves, electron wave as well as ion wave, propagate as the form of wave-packet modulated to the operation frequency of voltage pulse. The waves have the dispersion relation of ω∼(u d +u b +u n )k where the phase velocity is the addition of fluid such as drift velocity u d , gas blowing velocity u b , and plasma diffusion velocity u n . The waves are modulated to be the wave-packet of dω∼u g dk with the group velocity u g ∼c s 2/u n ∼(104–105) m/s where the acoustic velocity is c s ∼103 m/s and the diffusion velocity is u n ∼(10–102) m/s estimated in a plasma jet device. The plasma diffusion wave propagates resistively against the slope of plasma density gradient1.

Summary form only given. Electron cyclotron emission radiometry is a standard technique on most magnetically confined plasmas to measure the electron temperature profile, usually along the plasma mid plane. By combining heterodyne radiometry with optical imaging techniques it is possible to measure the electron temperature and fluctuations in this quantity in a two-dimensional section of the poloidal plasma plane.

Summary form only given. This paper presents a computational study of point-to-plane atmospheric helium plasma discharge. We employed a two-dimensional, axisymmetric fluid model to investigate the time-dependent characters of the discharge. Helium with small amount of nitrogen (impurity) was used as the working gas. The gap distance between the two electrodes was varied from 1mm to 15mm. The magnitude of the applied voltage's amplitude was in the range of 1kV∼10kV, and the frequency was 10 kHz. The coupled continuity equations for particles and electron energy equation were solved with the Poisson' equation using the finite element method with unstructured grids. Simulation results showed that the plasma needle operated as the corona discharge at low power and the mode transferred to glow discharge as the power surpassed certain critical value, and this value decreased either the frequency increased or the gap distance decreased. Furthermore, the simulation results were compared with the experimental results. The results showed that simulation results were in reasonable agreement with experiments.

Summary form only given. Study of structural phase transitions is of significant interest with fundamental point of view and, at present time, it is a subject of the intensive theoretical and experimental researches in various areas of physics. Such transitions are the phase transformations (of configuration, topology, polymorphic, or solid-liquid transitions) in strongly coupled systems, which consist in a structure reorganization of these systems and, in most cases, lead to a change of their symmetry type. Besides fundamental aspects, study of structural phase transitions is of special interest for development of nano- and micro- technologies, and of covers and materials with the defined properties.

Summary from only given. The study of the discharge in a focused beam of terahertz radiation in argon at pressures close to atmospheric was made. The range of breakdown electric fields and gas pressures at which the discharge occurs was determined. Discharge, had started at the focus of the beam, propagated in the region of weak fields, where the value of the intensity was substantially less than the breakdown one. The investigation of the discharge glow dynamics was made and it was shown that its front had moved towards the radiation with the speed of about 105 cm/sec. The estimation of the plasma density was made on the basis of the terahertz wave transmission coefficient measurements, and the value of the density exceeded the value of 1015 cm-3. The features of the discharge excited by radiation of the terahertz frequency range and its possible applications are discussed.
