Rapid Cross-Field Ion-Transport in a Plasma with Sheared Parallel-Flow

Abstract

Test-particle measurements of plasma cross-field ion transport show a dramatic change associated with the presence of sheared plasma flow parallel to a fixed magnetic field. Experimental conditions for enhanced transport are consistent with a simple model of shear flow instability. Observed modulations in the tagging transfer function suggest a nonlinear model for the ion dynamics, and a spatially varying shift in the ion gyrofrequency. The problem of determining electric fields from test-particle measurements is posed.

Magnetic field

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets.

Active transport

In cellular biology, active transport is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement. There are two types of active transport: primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient.

Ion thruster

An ion thruster, ion drive, or ion engine is a form of electric propulsion used for spacecraft propulsion. It creates thrust by accelerating ions using electricity. An ion thruster ionizes a neutral gas by extracting some electrons out of atoms, creating a cloud of positive ions. Ion thrusters are categorized as either electrostatic or electromagnetic. Electrostatic thruster ions are accelerated by the Coulomb force along the electric field direction.
