Experimental observation of the blob-generation mechanism from interchange waves in a plasma.

چکیده
The mechanism for blob generation in a toroidal magnetized plasma is investigated using time-resolved measurements of two-dimensional structures of electron density, temperature, and plasma potential. The blobs are observed to form from a radially elongated structure that is sheared off by the E x B flow. The structure is generated by an interchange wave that increases in amplitude and extends radially in response to a decrease of the radial pressure scale length. The dependence of the blob amplitude upon the pressure radial scale length is discussed.

A Study of Bit Condition for Generation Rx -Mode Waves: Interaction of Particles with Z/UH-Mode Waves
Interactions of charge particles with electromagnetic waves have important effects (linear and nonlinear) on the propagation of electromagnetic waves, and it can somewhat play a role in generation of the new mode waves. Besides, the particle energies can play an important role in causing instability in plasma. The values of parallel energy of the particles have been calculated so that they can ...
متن کاملA simulation study of RX-mode waves generation in the equatorial plasmasphere
The generation mechanism of RX-mode waves in the equatorial plasmasphere has not been well understood. The Akebono passing through the storm time geomagnetic equator shows the possibility of the local enhancement of RX-mode waves in association with intense Z-mode waves in the equatorial region. We use the initial parameters inferred from observational data from around the plasma-wave generatio...

In this paper, the governing equations of sea waves are analyzed nonlinearly and the energy extraction from the waves in the Lark and Faror islands in the Persian Gulf is determined. According to the data in the last 31 years, the waves of these two islands have the most incidence for the height of 0-0.4 m and 0.4-0.8 m corresponding for the time periodicity of 2.4-3 s and 3-3.6 s, respectively...

A detailed study of blob formation, dynamics, and the associated convective transport in the scrape-off layer sSOLd of tokamak plasmas is presented. Dissipation level in the system, in addition to the blob size, is shown to play an important role in determining whether a blob propagates as a coherent object. Nonlinear SOL interchange/ballooning modes are shown to be capable of creating blobs ne...
