Surface plasma oscillations in bubble

Solid State Communications, 1969
Abstract The case of surface plasmons in a particle is extended to a bubble with the semi-classical method.

Plasma conditions during single bubble sonoluminescence.

The Journal of the Acoustical Society of America, 2009
There is a remarkable lack of experimental data on the conditions created during cavitation bubble collapse. Indeed, only recently has strong evidence of plasma formation been obtained during single bubble cavitation. Here we have determined for the first time the plasma electron density and the ion broadening parameter during single-bubble ...

Oscillating plasma bubbles. II. Pulsed experiments

Physics of Plasmas, 2012
Time-dependent phenomena have been investigated in plasma bubbles which are created by inserting spherical grids into an ambient plasma and letting electrons and ions form a plasma of different parameters than the ambient one. There are no plasma sources inside the bubble. The grid bias controls the particle flux. There are sheaths on both sides of the

Plasma Bubble in an RF Reactor

IEEE Transactions on Plasma Science, 2008
A pronounced local enhancement of the argon plasma of the capacitively coupled reactor PULVA-INP is generated by applying an additional RF voltage at the central pixel (CP) of its adaptive electrode. This enhancement is observed by a large increase of the light-emission intensity.

Scalings for radiation from plasma bubbles

Physics of Plasmas, 2010
In this paper, electron trajectories are studied analytically in the rest frame of a plasma bubble using nonevolving, linear, radial electric and azimuthal magnetic fields in a spherical structure. The electron motion is broken into two distinct periods; one where it orbits around the periphery to the rear of the bubble, and one where it performs ...

Microwave excitation of submerged plasma bubbles

Journal of Physics D: Applied Physics, 2012
Abstract Steady-state models were formulated for spherical plasma bubbles, excited in water by an external microwave radiation source. The bubbles were assumed to be at rest relative to the surrounding water, and the energy absorbed by the plasma was balanced by energy loss through thermal conductance and convection to the surrounding ...

Tonks-Dattner resonances in a quantum plasma bubble

Physical Review E, 2016
We establish the spectrum of Tonks-Dattner mode resonances in a quantum plasma bubble and consider the spectral changes associated with plasma quenching and plasma expansion. The quantum corrections associated with the mode spectrum are specified, which can be used as a diagnostic tool to identify the quantum regime.

Equatorial F-Region Plasma Bubbles Studies

5th International Congress of the Brazilian Geophysical Society, 1997
Equatorial ionospheric plasma bubbles associated with equatorial range-type spread F, are regions where the plasma densities are much lower than the ambient plasma density and are aligned along the earth's magnetic field lines . The plasma bubbles can be observed by both the radio wave (e.g. ionosonde, radar, scintillation etc.) and optical techniques (
