The Morphology of Equatorial Plasma Bubbles – a review [PDF]

Journal of Astronomy and Space Sciences, 2015
Plasma bubbles that occur in the equatorial F-region make up one of the most distinguishing phenomena in the ionosphere. Bubbles represent plasma depletions with respect to the background ionosphere, and are the major source of electron density ...

Multibubble Sonoluminescence from a Theoretical Perspective

Molecules, 2021
In the present review, complexity in multibubble sonoluminescence (MBSL) is discussed. At relatively low ultrasonic frequency, a cavitation bubble is filled mostly with water vapor at relatively high acoustic amplitude which results in OH-line emission ...

Bubble Formation in ITER-Grade Tungsten after Exposure to Stationary D/He Plasma and ELM-like Thermal Shocks

Journal of Nuclear Engineering, 2023
Plasma-facing materials (PFMs) in the ITER divertor will be exposed to severe conditions, including exposure to transient heat loads from edge-localized modes (ELMs) and to plasma particles and neutrons.

Flat bubble regime and laminar plasma flow in a plasma wakefield accelerator

Physical Review Accelerators and Beams, 2022
A simple 2D model of the bubble formation in a plasma wakefield accelerator is developed and investigated. We show that in the case of a flat driver, the bubble may consist of two parts.

Effect of magnetic activity on plasma bubbles over equatorial and low-latitude regions in East Asia [PDF]

Annales Geophysicae, 2009
The dependence of plasma bubble occurrence in the eveningside ionosphere, with magnetic activity during the period years 2001–2004, is studied here based on the TEC observations gathered by ground-based GPS receivers which are located in the ...

Polarization and phase control of electron injection and acceleration in the plasma by a self-steepening laser pulse

New Journal of Physics, 2023
We describe an interplay between two injection mechanism of background electrons into an evolving plasma bubble behind an intense laser pulse: one due to the overall bubble expansion, and another due to its periodic undulation.

Cluster and Double Star multipoint observations of a plasma bubble [PDF]

Annales Geophysicae, 2009
Depleted flux tubes, or plasma bubbles, are one possible explanation of bursty bulk flows, which are transient high speed flows thought to be responsible for a large proportion of flux transport in the magnetotail.

Successive Westward Traveling Surges Driven by Sequential Plasma‐Sheet Bubble Injections

Geophysical Research Letters, 2022
The westward traveling surge (WTS) is one of the most notable manifestations of auroral substorms. Using the Rice Convection Model, previous study confirmed that a single plasma‐sheet bubble injection can result in the formation of WTS.

Plasma depletions lasting into daytime during the recovery phase of a geomagnetic storm in May 2017: Analysis and simulation of GPS total electron content observations

Earth and Planetary Physics, 2021
This paper reports that plasma density depletions appearing at middle latitudes near sunrise survived until afternoon on 29 May 2017 during the recovery phase of a geomagnetic storm.

A Study of the Topside Plasma Blob and Adjacent Bubble Near Sunrise in Low-Latitude Ionosphere During the Main Phase of August 2003 Storm

IEEE Access, 2021
In this paper, a plasma blob and an adjacent plasma bubble in low-latitude region at 245°E region near sunrise recorded by the Defense Meteorological Satellite Program (DMSP) F13 satellite around 840 km on 18 August 2003 were presented.
