Brief description

The core of the course will cover the essentials of plasma physics, including the nature of a plasma, motion of single charged particles in a magnetic field, magnetohydrodynamics, waves in plasma, and instabilities. The theory will be illustrated by examples from interplanetary space and the magnetosphere.


Occurrence of plasmas, temperature of a plasma, Debye shielding, plasma oscillations.

Motion of a single charged particle in
(a) a homogenous magnetic field; gyro-radius and frequency.
(b) a converging magnetic field; magnetic mirror.
(c) an inhomogenous magnetic field; drift motion.
(d) a magnetic field with a perpendicular electric field.

Magnetohydrodynamics: Maxwell's equations applied to a plasma; diffusion time of magnetic field in a plasma; "frozen-in" fields, magnetic Reynold's number.

Waves in a plasma: electron plasma waves, ion-acoustic waves, MHD waves, shear Alfven waves, fast-mode (compressional) waves.

Types of instability, two-stream instability (simple "doppler-shift" treatment), Rayleigh-Taylor and Kelvin-Helmholtz instabilities (qualitative treatment).
