Modern X-ray Science: Theory and Applications

Ever since Röntgen showed that X-rays could be used for medical applications, the role of X-rays in probing atomic and molecular level structures has proven invaluable in both materials science and modern medicine. This course showcases the research that 21st century X-ray sources opens up.

Information for admitted students Spring 2021

Congratulations! You have been admitted at Stockholm University and we hope that you will enjoy your studies with us.

In order to ensure that your studies begin as smoothly as possible we have compiled a short checklist for the beginning of the semester.

Follow the instructions on wether you have to reply to your offer or not.


Checklist for admitted students

  1. Activate your university account

    The first step in being able to register and gain access to all the university's IT services.

  2. Register at your department

    Registration can be done in different ways. Read the instructions from your department below.

  3. Read all the information on this page

    Here you will find what you need to know before your course or programme starts.


Your seat may be withdrawn if you do not register according to the instructions provided by your department.

Information from your department

On this page you will shortly find information on registration, learning platform, etc.

Welcome activities

Stockholm University organises a series of welcome activities that stretch over a few weeks at the beginning of each semester. The programme is voluntary (attendance is optional) and includes Arrival Service at the airport and an Orientation Day, see more details about these events below.
Your department may also organise activities for welcoming international students. More information will be provided by your specific department. 

Find your way on campus

Stockholm University's main campus is in the Frescati area, north of the city centre. While most of our departments and offices are located here, there are also campus areas in other parts of the city.

Pre-departure information

New in Sweden

X-ray science has evolved dramatically in the 21st century with the appearance of new generation synchrotron and x-ray free electron lasers (XFEL) sources. Such examples are the new Swedish national laboratory MAXIV in Lund, which is one of the world’s most brilliant synchrotron sources, as well as the novel European XFEL in Hamburg, which can generate ultrashort X-ray pulses and with a brilliance that is a billion times higher than that of the best conventional X-ray radiation sources.

The scope of this course is to give an overview of the x-ray methods that are used currently worldwide, starting from the fundamental theory behind and building up to modern state-of the art techniques. The course will include lectures covering the theory behind each technique, as well as simple model simulations to illustrate the basic principles of the different methods.

The content will follow the multidisciplinary character of the field by including examples from physics, material science, biology and chemistry. In addition, the participants will present a topic from a collection of research highlights. The course content includes x-ray diffraction applications from crystalline and non-crystalline materials, small-angle x-ray scattering (SAXS), wide-angle x-ray scattering (WAXS), x-ray spectroscopy (XAS, XES, EXAFS, ARPES), magnetic interactions (XMCD) and coherent diffraction (Imaging, Holography, XPCS).

Teaching during the spring semester 2021

During the spring semester 2021, lectures will be given remotely.  The course is examined through homework assignments and written and oral presentations of projects.

The course is using the learning platform Athena.

  • Course structure

    This is a second cycle course given at half speed during daytime and in every odd year. It can also be taken as a third-cycle course.

    Teaching format

    The teaching consists of lectures, group education, and laboratory exercises.


    The course is examined through written and oral project presentations, and through continual assessment of home exercises.
