Block Course

Accelerators and Synchrotron Radiation for Materials Research with Tutorials and a Practical Training

The KIT Light Source (KLS) with the Research accelerator KARA is an electron synchrotron that produces brilliant synchrotron radiation, such as in the x-ray range for a wide range of applications. A portfolio of experimental end stations is provided by several institutes at KIT to perform cutting-edge sample analysis.

Aim of the course is to make the KIT light source accessible to students and to let them benefit from the unique availability of this large-scale infrastructure. Synchrotron radiation is a central tool for materials analysis, but a systematic practical training in generation, properties and its use is demanded. Within 2 weeks the attendees acquire a basic knowledge in accelerator science, generation of synchrotron radiation, x-ray methods and the use of large-scale facility setups not only in lectures, but especially with a particular focus on the hands-on training.

lectures on:

basics of accelerator physics: accelerator types and applications, beam optics, measurement of beam parameters
generation of synchrotron radiation and its properties,
in situ and operando characterization on thin films, nanostructures, biological objects, energy-related materials
applications of different x-ray methods (Spectroscopy, Imaging, Scattering)

tutorials on:

deflection of charged particle beams at the example of a cathode ray tube
beam diagnostics devices using synchrotron radiation
KLS controls and diagnostics,
practical imaging and computed tomography analysis,
x-ray spectroscopy analysis
thin film analysis by x-ray reflectivity and scattering

Experiments and hands-on on synchrotron dynamics and diagnostics, selected x-ray experiments at KLS beamlines:

Beam optics simulation in MAD-X:	Learn how a model of a particle accelerator is set up and its beam optics is calculated. Based on that model you will explore the beam dynamics of an electron storage ring.
Beam characterization at the VLD port:	Using synchrotron radiation you will learn to use a set of diagnostics devices that will allow you to do a full 3D characterization of an electron bucnh in the KARA storage ring.
X-ray Imaging:	Learn how to set up an imaging beamline, how to choose the appropriate conditions for the beam, acquiring a CT scan, analysing the data
X-ray spectroscopy:	Learn to use the x-ray wavelength as an element- and chemically sensitive tool, map elemental content of samples, understand the information on chemical and local state of targeted elements
X-ray scattering:	Learn how to use x-ray scattering and reflectometry to characterize the crystal structure and morphology of functional thin films
