Module aims
The extended nature of the dominant Coulomb force between the particles in a plasma ensures that the behaviour is markedly different to that of gases where the forces are short range. As a result plasma has two distinct dynamic patterns associated with correlated long range motions - collective effects- and collisions. The module seeks to extend student knowledge in high energy density and laser plasma interactions with a view to equipping them for research in these areas. Some of the material will reinforce and revise undergraduate physics topics which may be important for students not proceeding to fusion work.
Module learning outcomes
Subject content:
Students commence the course by developing an understanding of plasma collective effects and collisions. Specifically,the course will enable students to:
Derive the Vlasov equation and understand the need for a collision operator in the context of Debye shielding.
Linearise the Vlasov equation to obtain the plasma dielectric function and understand how the form of the dielectric function gives rise to Landau damping.
Write down the form of the Krook and Fokker-Planck collision operators.
Derive the diffusion coefficients for a magnetised plasma and use this derivation to illustrate the need to close the fluid equations.
Explain the origin of the Braginskii transport relations
Understand the physics of laser interactions with plasmas of different scalelengths and a range of irradiances from 109 Wcm-2 to greater than 1022 Wcm-2
Appreciate the additional plasma physics involving radiation and pressure effects important in high energy density plasmas.
Derive the equivalent equation to the Boltzmann ratio for ionization balance for an equilibrium plasma the Saha equation.
Understand aspects of radiative transfer important in laser-produced plasmas and ICF.
Academic and graduate skills:
Students will obtain an understanding and an ability to apply knowledge in the above topics to research issues.
The topics cover a broad range of physics and so will serve to broaden and revise some undergraduate physics not covered elsewhere in the MSc.
