Study on Seasonal Variations of Plasma Bubble Occurrence over Hong Kong Area Using GNSS Observations

Remote Sensing, 2020
In this study, the characteristics and causes of the seasonal variations in plasma bubble occurrence over the Hong Kong area were investigated using the local Global Navigation Satellite System (GNSS) network. Generally, the occurrences of plasma bubbles

Generation of equatorial plasma bubble after the 2022 Tonga volcanic eruption. [PDF]

Sci Rep, 2023
Equatorial plasma bubbles are a phenomenon of plasma density depletion with small-scale density irregularities, normally observed in the equatorial ionosphere.

First Observation of Ionospheric Plasma Bubble Signatures by Ca+ Lidar at Low Latitude

Geophysical Research Letters
Ionospheric plasma bubbles refer to density depletion structures in the ionosphere, which are usually seen in the electron density profiles observed by radar, and have never been observed in the density profiles of metallic ions.

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 ...

GOLD plasma bubble observations comparison with geolocation of plasma irregularities by back propagation of the high-rate FORMOSA7/COSMIC 2 scintillation data

Frontiers in Astronomy and Space Sciences
Using the high-rate phase and amplitude scintillation data from FORMOSA7/COSMIC two mission and back-propagation method, we geolocate plasma irregularities that cause scintillations.

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 ...

Subfemtosecond Wakefield Injector and Accelerator Based on an Undulating Plasma Bubble Controlled by a Laser Phase. [PDF]

Physical Review Letters, 2021
We demonstrate that a long-propagating plasma bubble executing undulatory motion can be produced in the wake of two copropagating laser pulses: a near-single-cycle injector and a multicycle driver.

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.

Severe L-band scintillation over low-to-mid latitudes caused by an extreme equatorial plasma bubble: joint observations from ground-based monitors and GOLD

Earth, Planets and Space, 2023
The occurrence of plasma irregularities and ionospheric scintillation over the Caribbean region have been reported in previous studies, but a better understanding of the source and conditions leading to these events is still needed.

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 ...
