Plasma bubble domains: A magnetic bubble analog

Applied Physics Letters, 1982
Results are presented on the discovery of plasma bubble domains (PBD’s), which occur as regular patterns of localized glow discharges formed under ac excitation in an atmospheric pressure inert gas based mixture confined between large-area, closely spaced, plane-parallel, dielectric-covered electrodes.

Bursting Bubbles in a Complex Plasma

IEEE Transactions on Plasma Science, 2011
Time-space plots called “periodgrams” are used to study a complex plasma under the influence of a temperature gradient. The plasma contained microparticles that were illuminated with a laser. The complex plasma spontaneously formed bubbles that induced the movement of particles upward through the discharge chamber.

Energetics in the plasma bubble

Advances in Space Research, 1993
Abstract Energy budget in the plasma bubble is discussed in order to explain the electron temperatures observed at the height of 600 km. From calculations it has been shown that electron temperature profile inside plasma bubble can be basically explained as a function of energy input to the plasma bubble, the ion temperature and on the electron ...

Morphology of equatorial plasma bubbles

Journal of Geophysical Research: Space Physics, 1997
Some occurrence characteristics of plasma bubbles based on data from the ion drift meter aboard the Atmosphere Explorer E satellite are presented. Of 5200 bubbles detected between 250 and 475 km altitude, 65% had ion density depletions of less than 1 order of magnitude below the ambient ion density, and the occurrence frequency decreased with ...

Laser-produced plasma bubble

Physical Review E, 2000
In the aftermath of a plasma in atmospheric density H2 produced by a 6 ns, 600 mJ, 1064 nm, Nd:YAG laser pulse, a bubble develops behind the shock front. Within 2 micros the shock detaches from it, but the bubble persists for 100 micros before it is clearly turbulent.

Plasma in sonoluminescing bubble

Ultrasonics, 2006
With the new accommodation coefficient of water vapor evaluated by molecular dynamics model, the maximum temperature of a sonoluminescing bubble calculated with the full partial differential equations easily reaches few tens of thousands degrees.

Plasma Line Emission during Single-Bubble Cavitation

Physical Review Letters, 2005
Emission lines from transitions between high-energy states of noble-gas atoms (Ne, Ar, Kr, and Xe) and ions (Ar(+), Kr(+), and Xe(+)) formed and excited during single-bubble cavitation in sulfuric acid are reported. The excited states responsible for these emission lines range 8.3 eV (for Xe) to 37.1 eV (for Ar(+)) above the respective ground states ...

Properties of gluon plasma bubbles

Nuclear Physics B - Proceedings Supplements, 1992
The properties of droplets of gluon plasma are studied via Monte Carlo simulation. The finite size of the droplet and the finite interfacial width have large effects on droplet properties, giving rise to a phase diagram in which droplet radius and inner and outer temperatures are important.

Downdrafting plasma flow in equatorial bubbles

Journal of Geophysical Research: Space Physics, 1994
The electric field experiment carried aboard the San Marco D equatorial ionospheric satellite regularly measured updrafting in plasma depletion channels or “equatorial bubbles” which form on the bottomside of the nightside equatorial F region. We report here observations of downdrafting vertical plasma velocities inside such depletion regions in the ...

Plasma formation in underwater gas bubbles

Plasma Sources Science and Technology, 2014
The generation of plasma in underwater gas bubbles offers the potential to produce large volume plasma in water while minimizing electrode erosion. Such attributes are desirable for the design of plasma-based water purification systems. In this work, gas bubbles of diameter 0.4‐0.7mm were trapped in the node of a 26.4kHz underwater acoustic standing ...
