A | Autumn Term 2021-22 |
A plasma is an ionised gas containing free electrons and ions. The freedom of the electrical charges to move in response to electric and magnetic fields couples the charged particles so that they respond collectively to external fields. Plasmas are common place around the universe and have many important technological and biomedical applications on Earth, so the topic of plasma physics is important in many branches of science, linking to medicine, materials, fusion, particle acceleration and astrophysics. This course aims to introduce the basic plasma physics principles through a combination of physical pictures and mathematical analyses, often using examples of research activities at York to provide specific applications. The course will introduce aspects of plasma science and technology across magnetic confinement fusion, laser plasma interactions and low temperature plasma research activity at York.
Describe, both through physical pictures and mathematics, the orbits of individual particles in magnetic and electric fields: the cyclotron frequency, the guiding centre, the ExB drift, the gradB and curvature drifts and the polarisation drift.
Describe the physics of Debye shielding and be able to derive the Debye length mathematically. Write down the definitions of a plasma.
Demonstrate an understanding of the distribution function and how to derive plasma density and flux by integrating over velocity space.
Describe the physics of a plasma sheath and be able to drive plasma sheath parameters using a simplified sheath model.
Without rigorous mathematical derivation, describe how plasma fluid equations can be obtained from the kinetic equations for plasma evolution. Given the fluid equations, describe the physics of the individual terms.
Recall the requirements and criteria to obtain fusion and outline two confinement strategies for fusion plasmas.
Discuss weakly ionised plasmas and plasma breakdown and electron transport in dc electric fields
Recall the requirements and criteria to obtain fusion and outline two confinement strategies for fusion plasmas.
