Radio-frequency plasma transducer for use in harsh environments

Review of Scientific Instruments, 2007
We describe a compact transducer used to generate and modulate low-intensity radio-frequency atmospheric pressure plasma (RF-APP) for high temperature gap measurement and generation of air-coupled ultrasound. The new transducer consists of a quarter-wave transmission line where the ground return path is a coaxial solenoid winding.

Operating a radio-frequency plasma source on water vapor

Review of Scientific Instruments, 2009
A magnetically enhanced radio-frequency (rf) plasma source operating on water vapor has an extensive list of potential applications. In this work, the use of a rf plasma source to dissociate water vapor for hydrogen production is investigated. This paper describes a rf plasma source operated on water vapor and characterizes its plasma properties using ...

Charged-species profiles in electronegative radio-frequency plasmas

Physical Review E, 1995
The negative ion density profile in a low pressure oxygen rf plasma has been measured by a photodetachment technique. At an rf power of 10 W and a neutral pressure of 10 mTorr, a parabolic negative ion density profile is obtained with a peak density of 8\ifmmode\times\else\texttimes\fi{}${10}^{15}$ ${\mathrm{m}}^{\mathrm{\ensuremath{-}}3}$ and a ...

Radio frequency discharge with control of plasma potential distribution

Review of Scientific Instruments, 2012
A RF discharge plasma generator with additional electrodes for independent control of plasma potential distribution is proposed. With positive biasing of this ring electrode relative end flanges and longitudinal magnetic field a confinement of fast electrons in the discharge will be improved for reliable triggering of pulsed RF discharge at low gas ...

Radio-frequency opacity of a nonuniform plasma

Journal of Quantitative Spectroscopy and Radiative Transfer, 1965
Abstract The validity of a radiative transfer model applied to radio wave propagation in a nonuniform plasma is investigated with Maxwell field correlation functions. It is found that Oster's quasi-particle model of photon propagation in a general dispersive medium yields a different dependence of the absorption coefficient on refractive index than ...
