Plasma is sometimes described as "the fourth state of matter" and it has been said that most of the matter in the Universe is in the form of plasma. Plasma is present on, around and beyond the Earth. Plasma is produced artificially in gas discharges and in thermonuclear reactors. Natural plasma includes the interior of stars like the Sun, ionised gas clouds in space, and the Universe, in its first moments, was a very high-density plasma. The Earth's upper atmosphere is a plasma; this allowed Marconi to transmit radio signals across the Atlantic in 1901, which is a hazard for spacecraft, and is sometimes rendered visible as auroral displays. This module will describe the properties and study of plasma, in both Physics and Astrophysics contexts. Note that there is little or no overlap between this module, and "Physics of Fluids", "Atmospheric Physics" and "Particles, Accelerators and Reactor Physics".
Aims
To provide an introduction to the properties and study of plasmas in Physics and Astrophysics contexts. To illustrate the application of fundamental physics (especially electromagnetic theory) to Physical and Astrophysical plasmas. To develop students' problem solving skills. To develop students' literature researching and writing skills.

Description of Module Assessment
1: Problem Sheets weighted 15%Three problem sheetsThree problem sheets, each consisting of four problems based on the lecture material.
2: Essay weighted 15%1500 word essay1500 word essay (including 50-word abstract, figure and table captions, and references) on a topic of current interest in plasma physics. Students select their own titles, which will have a Physics or Astrophysics perspective depending on students' programme. Titles are subject to approval.
3: Unseen Exam weighted 70%Two hour written examinationUnseen examination using the standard format of 3 questions out of 5. Questions will be sectioned, and will test a mix of factual knowledge (book-work), unseen problem-solving requiring mathematical and/or numerical calculations, and descriptive answers.
