ED2235 Atomic Physics for Fusion 6.0 credits

Atomfysik för fusion

The research and development of controlled fusion involves knowledge and methods from many different branches of physics, such as electromagnetism, plasma physics, nuclear physics, atomic physics, surface physics and materials physics.

The purpose of this course is to make the student familiar with those aspects of atomic physics that are most important in fusion research. The focus of the course is on basic understanding of atomic collisions and applications in plasma modeling, plasma diagnostics and plasma surface interactions. Much of the course content is applicable also in other contexts in plasma processing and technology, ion implantation and radiation effects.

The examiner may apply another examination format when re-examining individual students.

Other requirements for final grade *

Having followed this course the student should:

·         Understand basic atomic collision physics in terms of the dominating mechanisms in physical processes like elastic collisions, electron impact ionization and excitation, and charge transfer.

·         Be able to exercise intuitive judgment of the relevant orders of magnitude, time scales, energy dependencies and similar in atomic collisions with fusion relevance.

·         Be able to account for the role of atomic collisions in fusion plasma physics and plasma surface interactions.

·         Be familiar with the use of fitting formulae and databases for cross sections, rate coefficients and derived quantities like stopping power or sputtering yield.

·         Be able to use atomic data in numerical modeling.
