Decided by: Education Board B
Date of Decision: 2015-04-16

General Information

Language of instruction: The course will be given in English


The aim of the course is to give deepened knowledge in the physics of accelerators and experience in both calculations and modeling of accelerator systems. In addition the course aims at providing a fundamental understanding of the Free Electron Laser and its accelerator systems.

The course focuses on accelerators for synchrotron radiation production (linear accelerators and synchrotrons), their mode of operation and layout and how their properties connect to different areas of use.
Different components in an accelerator are analyzed (electron guns, linear accelerators, storage rings, diagnostics, problems and solutions). The theory for magnets (dipole, quadrupole and general magnets) and how these are used in beam dynamics (particle optics, focusing, matrix formalism, betatron oscillations, beta functions, betatron tunes, emittance etc.) is described. This is used to build simulation models of accelerators.
The Free Electron Laser (FEL) process and different types of FELs (SASE, cavity FEL, harmonic generation, high gain harmonic generation and seeding) are described and the physics behind amplification is analysed.

Examination details

Grading scale: UV
Assessment: Written examination, passed laboratory excercises and hand-in exercises. Participation in the group and experimental work, study visits, demonstrations and related education and hand-in duties is compulsory. The final grade for the course is determined by the aggregated results of the different parts of the examination.
