Aim
The course provides a substantial introduction to the
interaction of X-rays with matter and its applications, with an
emphasis on diffraction and imaging.
Learning outcomes
Knowledge and understanding
For a passing grade the student must
- be able to explain the interactions of X-rays with matter on an
atomic scale
- be able to describe the principles behind X-ray detectors and
X-ray optics – and common implementations of these
- be able to explain X-ray scattering in non-crystalline and
crystalline materials
- be able to describe the principles for diffraction, and the
relation between the direct and reciprocal lattices
- be able to explain how the interaction of X-rays with matter
can be utilised for various imaging methods.
Competences and skills
For a passing grade the student must
- be able to calculate absorption and scattering of X-rays in
matter
- be able to integrate knowledge acquired from this course in a
scientific discussion.

Examination details
Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)
Assessment: The course consists of lectures, laboratory sessions, Group exercises, and project work. Participation is compulsory in laboratory sessions, project work and associated course components.
The assessment is based on a written exam, written assignments, evaluation of the project report and through the compulsory course components.
The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
Admission
Required prior knowledge: Basic atomic physics, electromagnetism (especially Maxwell's equations, vector analysis and Fourier transforms)and optics.
The number of participants is limited to: No
The course might be cancelled: If the number of applicants is less than 5.
