The generation and application of micro discharge plasmas

IEEE Conference Record - Abstracts. 1999 IEEE International Conference on Plasma Science. 26th IEEE International Conference (Cat. No.99CH36297), 2003
Summary form only given. The dielectric barrier discharge lamp has been developed and commercially supplied as a tunable UV light source. However, a high-voltage (over several tens of kilovolts) is required to drive the device. We have attempted to reduce the driving voltages without reducing the light intensity by using new types of micro discharge ...

Ionization coefficients for argon in a micro-discharge

Plasma Sources Science and Technology, 2013
Ionization coefficients are measured for electrons in a dc micro-discharge in argon from optical emission profiles. The micro-discharge is operated in the Townsend regime between two parallel-plate electrodes. Axial profiles of emission are obtained with sufficient resolution to provide spatial ionization coefficients.

Micro-discharge and electric breakdown in a micro-gap

Journal of Micromechanics and Microengineering, 2000
Very weak light emission due to micro-discharges in the micro-gap of an electrostatic actuator under a high electric field can be imaged using a highly sensitive CCD camera. In this paper, we focus, in particular, on the relation between the micro-discharge and the electric field breakdown.

Rapid measurement of micro discharging gap

SPIE Proceedings, 2011
There is micro discharging gap to be measured between negative electrode and positive electrode in precise micro electrical discharging machining. The state of the discharging gap is complex and variable. There are many factors which have effects on the state.

An Ultrahigh Current Density Micro Discharge

IEEE Transactions on Plasma Science, 2011
At atmospheric pressure, a micro thin-cathode discharge operates in a self-pulsing mode with a peak current density of several 105 A/cm2. The V-I characteristic of the discharge indicates that the self-pulsing is due to a periodic ignition of a spark discharge. In the self-pulsing mode, the plasma emission was observed by a CCD camera. The camera image

Numerical study of electrical characteristics in RF micro discharge

2015 4th International Conference on Systems and Control (ICSC), 2015
In this paper, a numerical study of electrical characteristics is investigated for a argon micro discharge generated by a radio- frequency excitation (13.56 MHz) at high pressure (100Torr) and low voltage (150V). The results show that the rf voltage is responsible for the increase of plasma potential. Moreover, we found that the rise of gas temperature

Influence of water conductivity on micro-discharges from raindrops in strong electric fields

Atmospheric Research, 2005
The influence of water conductivity on micro-discharges from raindrops has been studied by submitting water drops of different conductivities, falling at terminal velocity, to strong horizontal electric fields.

Plasma display panel with micro-discharge array

Optoelectronics Letters, 2005
A novel discharge device is designed on the basis of the configuration of micro-hollow cathode discharge (MHCD). By using many MHCDs in parallel connection, a micro-discharge array can be constructed. With the micro-discharge array, a high-pressure high-current density glow discharge plasmas can be formed to make a plasma display panel (PDP).
