A novel microplasma device, for the first time, was constructed in a cavity Poly (dimethylsiloxane) (PDMS) chamber with two normal syringe needles serve as both the gas channels and the electrodes. This device employs argon plasma with direct current for molecular fragmentation and excitation. The microplasma is generated at atmospheric pressure in the PDMS chamber of 0.5 mL (5 × 10 × 10 mm(3))...

In this study, a review and discussion has been made on the research work of heat transfer in manifolds previously done. Since it is difficult to determine the heat transfer coefficients in different areas of a suction or discharge chamber by using conventional methods, the mass transfer analogy -sublimation of naphthalene has been used to develop the heat transfer correlations for the four are...

Isolated false tendons excised form dog hearts were mounted in a three-chamber tissue bath. Isotonic sucrose solution was perfused in the central chamber to provide a region of depressed conductivity between the fiber segments in chambers 1 and 3, which were perfused with Tyrode's solution. The electrotonic influence of spontaneous or driven responses evoked in chamber 3 during the first half o...

Much of on-chip storage is devoted to transient, often short-lived, data. Despite this, virtually all on-chip array structures use sixtransistor (6T) static RAM cells that store data indefinitely. In this paper we propose the use of quasi-static four-transistor (4T) RAM cells. Quasi-static 4T cells provide both energy and area savings. These cells have no connection to Vdd thus inherently provi...

Laser initiated, free standing discharge channels offer many attractive advantages for the transport and focusing of intense ion beams [1, 2]. Discharge plasmas can neutralize both current and space charge of such beams, while the azimuthal magnetic field provides strong focusing all the way through the channel. Experiments at GSI have produced 50 cm long stable plasma channels with peak curren...

The object of the research is partial discharges arising in a sample insulation pressboard. In most modern high-voltage direct current transmission schemes based on voltage-source converters six-pulse or twelve-pulse are used. signal waveform voltage side not pure and it has alternating component. Since discharge activity under distorted much different than that voltage, ripples harmonics subje...

A high-power, rectangular discharge chamber is being investigated by the University of Michigan for operation with multiple discharge cathode assemblies (DCAs). The multiple cathode approach attempts to increase thruster lifetime by operating three DCAs sequentially, possibly providing a threefold increase in discharge life. Previous multiplecathode electric propulsion devices, such as the SPT-...

The effect of addition of xenon on the long term homogeneity of discharges in F2 and ArF excimer laser gas mixtures was investigated in a small-volume discharge chamber. The gas mixture in the discharge chamber was preionized by X-rays. A special electrical excitation circuit containing a pulse forming line provided a long, squareshaped current pumping pulse of a predetermined duration to the d...
